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.

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.

• Derivation of climatology of rainfall based on 8-10 years Radar data at one or more location in India.
• Weather radars provide surface rainfall intensity estimates based on Marshal Palmer relation, these estimates have high spatial and temporal resolution in comparison to surface observation network. Hence, an attempt to derive climatology of rainfall based on weather radar past 8-10 yrs data is being made. This work serves two purposes: first namely derivation of climatology of rainfall based on Doppler weather radar 8-10 yrs data. Second is to prepare climatology for extreme weather events associated with Western Disturbance such as hailstorm, thunderstorm which impacts northern India during winter months mainly.
OBJECTIVES
• It would be useful for IMD (India Meteorological Department) to have a catalogue of climatology of rainfall events over a particular area.
• Climatology of radar rainfall could be utilised for climatological application such as estimation of probabilities of extreme rainfall which is used for design purposes in water management.
• Climatology of extreme weather events along with hydrometeor details could be utilised by forecasters and academics & designers associated with water management.

Atmospheric Pollution and Himalayas
The Himalayas and Tibetan Plateau are referred as the Third Pole (TP). The Himalayas are a massive about 2,500-kilometres arc-shaped stretch of lofty mountains with an average elevation over 4000 m extending across Pakistan, China, India, Nepal, and Bhutan. This third pole region is the home to about 1,000,000 km2 of glaciers, containing the largest volumes of ice outside the polar regions, and the origin of 10 largest rivers of Asia, making it the “Water Tower of Asia.”
Due to the high altitude and larger area, the region plays a significant role in Earth's climate system and water cycle with unique and complex interaction of atmospheric, cryospheric, hydrological, geological and environmental process. However, the water tower of Asia is now in danger due to rapid warming and noted for its higher rates of glacier melt, and the associated hydrological shifts that affect water supplies over 1.4 billion people in Asia and contribute to global sea-level rise.
Studies shows that the atmospheric pollutants contribute to climatic and cryospheric changes through their effects on solar radiation and the albedos of snow and ice surfaces. The atmospheric pollution, climate change and cryospheric changes are closely related and necessary to be investigated in a coupled and integrated framework is our prime interest. The air quality impacts the entire region through the summer monsoon and winter westerlies, which can transport pollution such as black carbon and other aerosols over long distances. The Hindu Kush Himalayas (HKH) are sensitive to climate change. The air pollutants originating within and near the HKH region magnify the effects of greenhouse gases and accelerate the melting of the cryosphere through the deposition of black carbon and dust that effect the circulation of the monsoon, and the distribution of rainfall over Asia. Emission sources in this region also vary in different countries, in terms of magnitude as well as source factors and need to be investigated separately.
Our interest is on five primary pollutants (CO, NOx, SO2, BC, and PM2.5). Different pollutants may be emitted by the same source, while many of them are chemically transformed in the atmosphere, forming secondary pollutants, such as secondary aerosols (both organic and inorganic, nitrates and sulphates) and tropospheric O3. In addition, the HKH receives trans-boundary pollution from other parts of Asia. The air pollution in this region not only effect human health, but also the climate, the cryosphere, monsoon patterns, water availability, and agriculture product. With its unique geographic and atmospheric structure, the TP play an important role in regional climate. The basic atmospheric and land, thermal and dynamic characteristics over the TP, as well as their relationships with the Asian monsoon based on recently available datasets, are the important subject of our research.
OBJECTIVES
• The study of tropospheric ozone change driven by climate change across the Third Pole region.
• Study of the potential radiative effect of Black Carbon (BC) over the southern part Himalayan region.
• Study of the contribution of transboundary pollution to total loading of atmospheric pollution in the TP region.
SOCIETAL IMPORTANCE
The TP region is fresh water tower of Asia. To protect it is our responsibility. The main issues of air pollution in this region is a transboundary issue and has impacts on the region-wide weather, climate, and agriculture, as well as socioeconomic sectors. Regional coordination and collaboration is important to enhance the mitigation at the local and national and regional levels.

Long-Term Changes in Winter Blooms in the Arabian Sea: Characteristics and Physical Forcing
The Winter bloom in the Arabian sea, which is in conjunction with the North Easterly winds had been subjected to spatio-temporal changes during the last decade. Our research interests are focused on the role of oceanic and atmospheric forcings in influencing the bloom characteristics. We use reanalysis, observation, and numerical models to understand the process that drives the bloom.
OBJECTIVES
• Long-term changes in winter bloom of Arabian Sea
• The drivers of winter bloom and its temporal changes
SOCIETAL IMPORTANCE
Phytoplanktons form the base of the marine food web and recent changes in the ocean condition and plankton composition in the Arabian Sea had adverse effect on the Net Primary Productivity, carbon budget and marine fisheries. Scholarly attention in plankton blooms especially HABs and hypoxia followed by it helps to lessen the harm done to the ocean ecosystem and to the human environment.

Vegetation dynamics and climate – vegetation interactions
One of the most discussed as well as debated topic among contemporary researchers is climate change. The changes in terrestrial vegetation serves as one of the major indicators for climate change and variability. In recent decades, land use change and climate variability have been affecting the terrestrial biosphere through changing the energy balance. Continuous monitoring of vegetation dynamics is crucial for understanding the biogeochemical processes and its possible effect on our climate system.
From atmosphere to ocean to soils and even in the Earth’s crust, carbon is distributed everywhere. The terrestrial biosphere includes carbon in plants, both dead and alive, animals, soil and the microorganisms. The carbon cycle plays a key role in regulating the earth’s climate by controlling the concentration of carbon dioxide in the atmosphere. Carbon dioxide is one of the main greenhouse gases, contributing to the global warming. Primary productivity is a key component of carbon cycle and are important to understand sink and source capacity of the terrestrial ecosystems.
Remote sensing image analysis and modelling provides the estimation of photosynthetic and productivity trends along with their seasonal as well as decadal variations for providing better insights in understanding of climate changes, carbon cycle and energy exchanges between vegetation and atmosphere.
OBJECTIVES
• Computation of Photosynthetic trends in the last 2 decades.
• Computation of Productivity trends in the last 2 decades
• Exploration the relation of vegetation and climate variability.
SOCIETAL IMPORTANCE
• The study brings into light the regions which requires increase of green cover for maintaining the balance in the terrestrial carbon cycle and maintaining an ambient environmental and atmospheric conditions.
• The impact of anthropogenic activities and intrusions on terrestrial carbon cycle and inducing climate change is also perceived.

07/2021 - Present : Junior Research Assistant, Accuracy Estimation of INSAT 3D/3DR Temperature, Ozone and Water Vapour measurements: Application to Air Sea Interaction Studies
Air-sea interactions of Ozone, Temperature and Water Vapour
Ozone and water vapour are two important climate relevant trace gases in the atmosphere, and temperature is one of the most significant climate parameters. Therefore, careful and consistent monitoring of these gases and temperature is essential for understanding temporal and spatial changes of these parameters in the past and thus, predicting expected changes of climate in future.
Long-term monitoring of trace gases also demands novel techniques and new sensors for continued environmental surveillance. The INSAT-3D/3DR instruments are the contributions of India towards understanding temporal evolution and spatial variability of these traces gases, and their connection with climate.
Since it is necessary to validate new measurements prior to their scientific use, we propose the validation and accuracy estimation of ozone, temperature and water vapour retrievals of the INSAT- 3D/3DR measurements. These validated measurements then will be used for the studies on Monsoon Inversion over the north Indian Ocean region and ozone-ENSO relationships in the tropics.
OBJECTIVES
• Comprehensive validation, error estimation and drift analysis of INSAT ozone, temperature and water vapour retrievals.
• Assessment of differences between INSAT-3D and 3DR measurements
• Analysis of variability and trends (supplemented by other data sets) in ozone, temperature and water vapour over Indian regions as observed by INSAT and other satellite measurements
