The workshop is expected to focus on the present status and future prospects of the subject of climate change and Aerosols in the national and global context, scientific and technical challenges; identification of thrust areas, and the way forward. The workshop aims to identify some broad sub-themes, potential groups of investigators and institutions who could actively and meaningfully participate in the proposed National Network Programme on Climate Change and Aerosols.




Four thematic areas are identified where inter-disciplinary research is required to advance the existing knowledge in order to understand and quantify aerosol impacts on Earth system (ecology, environment, weather, climate and health).

1. Aerosol-Cloud-Precipitation Interactions with special focus on Himalayas

This is the largest uncertainty in climate models. Though CAIPEEX and CTCZ have provided some valuable data of aerosol and cloud parameters, still various issues remain unknown.


2. Aerosol-Cryosphere River system Interactions and their impacts on Himalayan ecosystem


Large aerosol load over India and its transport to the Himalayan region is reality. There is a need to understand how aerosols interact with cryosphere and also with the river systems when they are deposited.


3. Aerosol-Biogeochemical Feedback


Terrestrial biosphere is a key regulator of the Earth’s climate. There is evidence that dust particles can trigger phytoplankton bloom by providing the necessary nutrients. Aerosols impact biogeochemistry in two ways:

(1) directly by influencing the exchange of nutrients through atmosphere and

(2) indirectly by modifying the climate.


4. Organic Aerosol (OA) and Bio Aerosols Processes: Measurements and Modelling


Organic aerosols contribute ~20-50% of the fine aerosol load. Yet poor knowledge exists for organic aerosol processes and its representation in climate models.

Bio-aerosols, directly released from the biosphere, are least understood amongst all types of aerosols. They play important role in modulating the Earth’s climate directly and indirectly by serving as CCN and IN and also have impacts on human health. In India, very few studies exist.
