PROFESSIONAL EXPERIENCE

Agricultural Emissions

My research area includes emissions studies from the agriculture sector. We work on quantifications of hotspots of different atmospheric gases such as NH3 and Greenhouse gases (GHG). A greenhouse gas (GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect on planets.

The primary greenhouse gases in Earth's atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). I am working on CO2 and CH4 as a part of my doctoral thesis. Over the last fifty years, the increase in agricultural production to meet the food demand of a growing population has resulted in a near doubling of GHG emissions from agriculture, forestry and fisheries. Globally, agriculture faces the triple challenge of increasing production to meet the growing food demand, adapting to changing climatic conditions and reducing agricultural emissions from the fields. Agricultural emissions basically constitute greenhouse gases (GHG) and non-greenhouse gases emissions coming from large land areas.

The changes in climate that can be expected as a result of the ongoing emissions of greenhouse gases could have large, harmful impacts on both plants and animals by making them more vulnerable to the attacks of insects/pests and diseases. Moreover, CO2 and CH4 are the topmost two gases that contribute to the greenhouse gases (GHG) emissions at a global level. This growth in agriculture and associated emissions will occur mostly in Asian and African countries, where a large percentage of the population depends on agriculture and allied sectors for their livelihoods. As per EDGAR v 4.3.2 database report of 2016, total global GHG continued to increase at the rate of 0.5% annually reaching up to 49.3 Gigatons of CO2 equivalent.

My study region is the whole of India. Since, India is the third-largest emitter of greenhouse gases (GHG) in the world after the USA and China, therefore, to reduce the emissions at the global level, India has a vital role to play. The agricultural sector is responsible for 18% of gross national GHG emissions in India too mainly through rice cultivation, livestock production, fertilizer use and burning of crop residues. Continued emissions of greenhouse gases will lead to further climate changes. Future changes are expected to include a warmer atmosphere, a warmer and more acidic ocean, higher sea levels, and larger changes in precipitation patterns. The extent of future climate change depends on what we do now to reduce greenhouse gas emissions. The more we emit, the larger future changes will be.

Greenhouse gas concentrations in the atmosphere will continue to increase unless the billions of tons of our annual emissions decrease substantially. Increased concentrations are expected to increase the earth’s average temperature, influence the patterns and amounts of precipitation, reduce ice and snow cover. It will raise the sea level, increase the acidity of the oceans, increase the frequency, intensity or duration of extreme events, shift ecosystem characteristics, and also increase threats to human health. These changes will impact our food supply, water resources, infrastructure, ecosystems, and even our own health.

Many greenhouse gases stay in the atmosphere for long periods of time. As a result, even if emissions stopped increasing, atmospheric greenhouse gas concentrations would continue to increase and remain elevated for hundreds of years. Moreover, if we stabilized concentrations and the composition of today's atmosphere remained steady (which would require a dramatic reduction in current greenhouse gas emissions), surface air temperatures would continue to warm.

OBJECTIVES

• To analyze the spatial and temporal variability of ammonia using satellite data and exposing its agriculture sources.
• To identify and quantify the connection of particulate matter with ammonia and its effect on agriculture.
• To identify relation of wet deposition of NH3 and temporal variability of methane over Indian regions.
• To analyze the spatial and temporal variability of carbon dioxide and methane and it’s offset over croplands in India.

SOCIETAL IMPORTANCE

• My work focus on identification of major agricultural emission hotspots in India, this will help in making a road map to reduce these emissions.
• Our work also suggests the methods and strategies to mitigate the agricultural emissions.

Carbon Sequestration

I work on sustainability science (environmental sustainability) with an emphasis on food and nutritional security in climate change context. My current affiliation is with Centre for Oceans, River, Atmosphere and land Sciences (CORAL), Indian Institute of Technology, Kharagpur, India, as a doctoral candidate and working as a visiting scholar at ICRISAT Hyderabad. My research focuses on the comparative assessments of conventional and new flanged concepts to sequester carbon in soil and analysing its effect on soil carbon fractions, crop production, soil fertility and potential emissions arising from chemical fertilizer use in soil.

Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites. My research integrates scientific principles from soil science, agronomy, biology, and chemistry to elucidate how soils provide essential ecosystem services. My research also provides an understanding of how soil properties relate to and can be managed for optimal agricultural production, and agro-waste disposal and management. I address nutrient management, sustainable agriculture, soil biogeochemical cycles and climate change.

We build on soil as well as with it and in it. Soil plays a vital role in the Earth's ecosystem. I also work on designing and production of biochar based on the need of soil. Being an agricultural systems researcher by training my focus is on agroecology and environmental footprints of agriculture. I have experience of working with crop simulation models on DSSAT platform and DNDC. Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.

As our awareness of the value of natural and managed ecosystems services grows, new biodiversity, carbon, and water markets are emerging, such as the Chicago Climate Exchange, and the nutrient trading programs under the new executive order on the Protection and Restoration of the Chesapeake Bay. These markets place an economic value on management practices which increase those ecosystem services, producing goods that enhance human and environmental health.

OBJECTIVES

• Preparation, characterization and comparative evaluation of biochar with compost for soil nutrient dynamics
• Effect of biochar biofertilizer as compared to conventional organic and inorganic nutrient management in rice and maize
• Evaluation of residual effect of biochar and compost fertilizers on legume yield

SOCIETAL IMPORTANCE

• To improve soil organic carbon and soil fertility for food security
• To promote use of agro-residues and avoid their wasteful burning

Tropospheric Ozone In Antarctica

With severe impacts on human health and agricultural output (crop damage in India upto 3.5 million tonnes a year, tropospheric ozone is a prominent air pollutant and greenhouse gas in spite of being only 10% of total column amount.

However, Ozone is not only a greenhouse gas and biological irritant but also an atmospheric cleansing agent which rids the atmosphere off hazardous gases through production of hydroxyl radicals and is beneficial if it is present in the stratosphere in abundant amount as it prevents harmful sun rays from penetrating through the troposphere to the Earth’s surface. Ozone exerts considerable radiative forcing too with recent estimate being 360 mW/m2 which is 25% of the same exerted by CO2.

Climate variabilities ranging from interannual to decadal scales like El Niño and the Southern Oscillation (ENSO), Pacific–North American teleconnection (PNA), North Atlantic Oscillation (NAO), Antarctic Oscillation (AAO), Pacific Decadal Oscillation (PDO) etc. has been reported to influence the tropospheric ozone at remote locations.

Despite of having tremendous climatic, agricultural, compositional and health repercussions, variability of ozone (tropospheric in particular) vis-a-vis circulation changes (due to climate change and stratospheric ozone hole recovery) is still poorly understood.

Given this background, it is imperative to ask the following relevant questions:

o How is the ozone in the Antarctic distributed both vertically and spatially?

o Is the ozone hole in the stratosphere healing? If yes, how confident are we about our analysis showing the recovery trends?

o Is there any evidence of recovery in atmospheric layers which experience near complete destruction of ozone i.e. ozone loss saturation layers?

o How is the recovery affecting the tropospheric ozone trends?

o How do O3 profiles cluster for various regions, each of which are known to exhibit differing O 3 distributions?

o What are the links among the O3 profile clusters, meteorology, and chemistry, and how do they depend on latitude or region?

o How do the ozone recovery in the stratosphere and trends in tropospheric ozone affect the surface climate in the Antarctic and how is it correlated with the increasing greenhouse gases?

I’ll be using state of the art Physical models and Causal Discovery and Inference methods based on Artificial Intelligence to answer these questions.

OBJECTIVES

• Evaluation of ozone recovery in Antarctic loss saturation layer.
• Investigation of the tropospheric ozone trends and their climatic implications.
• Examination of the spatial heterogeneity in Antarctic ozone distribution using Artificial Intelligence (AI) based new methodology developed during the study

SOCIETAL IMPORTANCE

• Tropospheric ozone is a greenhouse gas and an air pollutant having serious adverse effects on human health and agricultural production. Changes in tropospheric ozone in Antarctica would have a profound impact on the future climate.
• Tools developed during the study will be open sourced and can be used by others too.

Tropical cyclone and climate Change.

Tropical cyclones are one of the most devastating storms. Though it is
disastrous, it also has some positive effects such as bringing rainfall, decreasing
pollutants etc. Our North Indian Ocean which has Bay of Bengal and Arabian
Sea is home to tropical cyclones and also it is warmest of all oceans. In the
context of climate of climate change, it is important to consider the impact of
tropical cyclones on it. In the recent years, there is an increase in the number of
tropical cyclones and 2019 being an anomalous year as far 2019 is concerned.
Therefore, the effects of tropical cyclones on climate change has to be
understood.

OBJECTIVES

The impact of climate change on tropical cyclones in the NIO

The impact of tropical cyclones on upper ocean dynamics: Cold wakes

The impact of tropical cyclones on precipitation, particulates and trace gas
distribution

SOCIETAL IMPORTANCE

Tropical cyclones are increasing and has major adverse effects on the society and
therefore the work is significant with respect to changing environment.

Atmospheric CO2 and Air-Sea exchange

I work with atmospheric CO2 and its exchanges between the atmosphere and the ocean under the guidance of Prof. Jayanarayanan Kuttippurath at the Centre for Ocean, Rivers, Atmosphere, and Land Sciences (CORAL), Indian Institute of Technology Kharagpur.

As part of the project O-MASCOT sponsored by INCOIS Hyderabad, we deal with the customization of an ocean-atmosphere coupled model to study the nutrient exchanges between the atmosphere and the ocean. The ocean is the largest carbon sink, and literature estimates about 40% of the carbon get stored in the oceans since industrialization.

My research concentrates on the increasing trend of CO2 in the atmosphere and its impact on the marine ecosystem, especially in the Indian Ocean, analyzed using satellite measurements and numerical models.

OBJECTIVES

• Development of an ocean-atmosphere coupled model.
• Study on the impact of atmospheric pollution/aerosol on the biogeochemistry of Bay of Bengal.
• Study on the impact of atmospheric deposition in the Bay of Bengal on regional Climate.

SOCIETAL IMPORTANCE

• The changing behaviour of the ocean in absorbing and releasing carbon affects the marine environment. The physical and chemical changes of the seawater resulting from unbalanced carbon exchanges will have a drastic effect on flora and fauna.

Ocean-biogeochemistry in an atmospheric input perspective

Oceans are the basis of life. It is major source of oxygen and are also a reservoir for Carbon Dioxide. Ocean form 70 % of the earth. While earth comprises of Hydrosphere, Atmosphere, Biosphere and Geosphere, Atmosphere and Ocean are of major importance.

Ocean together with atmosphere gives rise to air sea interactions which causes weather and climate. These climatic aspects not only refers to physical ones, but also the biological ones. We are all very much aware of the climate change and the associated changes in the physical parameters (eg SST increase, sea level rise).

It is also important to consider the effect of anthropogenic activities which also affects marine and coastal ecosystems. Through my research I look into the effects of atmopsheric pollution on the oceanic biogeochemistry.

I would be making use of coupled ocean atmospheric chemistry ocean biogeochemistry model for this purpose to incorporate the effects of atmospheric chemistry on the ocean biogeochemistry.

OBJECTIVES

• To identify the general trend of Chlorophyll in North Indian Ocean and some special cases such as Cyclones using satellite derived datasets and estimate the same using ROMS-BGC model.
• To estimate the trend of chlorophyll in the coupled models with and without chemistry input from Atmospheric Model

• To estimate the Net Primary Productivity in NIO using the satellite measurements and also from the model simulated Chlorophyll.

• To estimate the Nitrate cycling using coupled model.

SOCIETAL IMPORTANCE

• It helps to understand the impact of pollution on the marine ecosystems which is also the effect of anthropogenic activities and long term climate change

ATMOSPHERIC WATER VAPOR MEASUREMENTS AND CLIMATE CHANGE

I am working on the broader aspects of atmospheric water vapor measurements and its effect on climate change. As far as now we are working on the trends over indian region for precipitable water vapor in the tropospheric water vapor level and trying to figure out its effect on climate change over the whole indian region and also over its several regions.

We will also give our focus onto figuring out a solid understanding of the mechanism by which precipitable water vapor and its changes over time influences atmospheric processes. Then we will try to figure out about the precise knowledge of its concentration in the stratospheric region and also about the understanding of mechanisms by which it influences atmospheric processes. We will also try to figure out the solid reason behind the stratospheric water vapor change which is assumed to be caused by climate feedback or some internal variability and also see the long term trends of it.

Overall our point of purpose will be developing a solid understanding of the mechanism by which water vapor influences other atmospheric phenomena, look over long term trends which are somehow till now less available and through which develop a picture of the factors controlling the water vapor and vice versa.

OBJECTIVES

SOCIETAL IMPORTANCE

This will help to develop a certain level of understanding about the mechanism by which water vapor influences some atmospheric processes and also about some factors which controls the
water vapor amount in atmosphere. The long term trends over time of precipitable water vapor will help us to have depth of knowledge about those region’s particular climate change patterns and also its effects on socio-cultural processes.

Ozone and Chlorine Chemistry in the Stratosphere

Ozone has been vital for sustaining life and making earth habitable. Without Ozone
life on earth would be restricted only to the oceans. Ozone provided the shield and
allowed life to leave ocean and populate land.

Anthropogenic activities during the
Industrial revolution led to emissions of certain ozone destructing gases such as
CFCs and other chlorine and bromine containing species in the atmosphere.
Results were significant decrease in stratospheric ozone levels, especially over
Antarctic during spring.

My research explores the chemistry and dynamics of
stratospheric ozone layer. I am examining long-term changes in the Earth’s ozone
layer and how such changes may influence climate. I analyse different satellite and
ground based observations seeking for signs of recovery in ozone levels. My
research focus is on estimation and attribution of long-term trends of stratospheric
trace species like O3, HCl, ClO measured from various satellite observations.

I am closely investigating chlorine as an ozone destructing species, as well. This is
because a single chlorine atom has the capacity to destroy thousands of ozone
molecules.

OBJECTIVES

My vision is to gain an understanding on the science of ozone evolution during the “ Anthropocene” and when it is expected to recover to pre- industrial levels. I hope to understand present and future of ozone during our times.

SOCIETAL IMPORTANCE

Humans have altered the composition of the atmosphere. Human-induced changes
in the global climate system and in stratospheric ozone pose a range of health risks.
Stratospheric ozone changes can impact climate by changing the large-scale
atmospheric state. Stratospheric ozone acts as a sponge, absorbing the very harmful
UV rays from Sun.

Changes in ozone means change in the amount of UV radiation
that reaches the surface, both impacting surface temperatures and biogenic
processes. Thirty years after the worldwide ban on Ozone depleting substances
(ODSs) following the Montreal Protocol 1987, it is important to
ensure that the International agreement and its subsequent revisions are still
accomplishing their objectives. My focus is on understanding the current status of
this protective shield of the atmosphere. Also, I am motivated to understand the
major factors expected to control stratospheric ozone in the rest of this century.

Hopefully through my research, I can contribute to the scientific community and
every living species on planet Earth.

Study of Cyclone Activity and Air-Sea Interaction Over Bay of Bengal Region Using Data and Numerical Model

Currently I am working on “ Influence of Madden Julian oscillation (MJO)on tropical cyclone genesis over the North Indian Ocean (NIO)”. The study includes the analysis of influences caused by the propagation of MJO on genesis of tropical cyclones in the NIO region during the post monsoon region. The active phase of MJO is occurring frequently in October, November, and December, because of that our period of study is focused on these months.

My second objective includes simulation of cyclones using coupled model COAWST and to study the effect of BLT and MLD. The third objective consists of mid tropospheric warming effects within the cyclone and the final objective to retrieve the ocean currents using maximum cross correlation method

OBJECTIVES

● Study MJO intraseasonal oscillation with cyclone
● Cyclone simulation in BOB and study the effect of BLT, and MLD with cyclone
● Mid tropospheric warming effects within cyclone
● Study on Ocean currents retrieval by Maximum Cross Correlation method

SOCIETAL IMPORTANCE

● Coastal zone of India is vulnerable and highly-susceptible to tropical cyclones and storms.
According to national disaster management authority (NDMA) out of 7516 km long coastline
about 5700 km is prone to cyclones and Tsunamis, so study of tropical cyclones is highly significant.
