Atmospheric Sciences
The anthropogenic impact on climate in the present era alarmingly exceeds due to known changes in natural processes, such as in solar radiation and volcanic eruptions. Increasing atmospheric source of GHGs due to burning of fossil fuels are strong agents in alterations of global climate. Agriculture, forestry, land use practices, industrial activities, waste disposal and transportation, have also altered the terrestrial, coastal and ocean ecosystems; thus affecting the biological productivity, water resources, and chemistry of global atmosphere. Certain fundamental changes are also evident in terms of decline in stratospheric ozone content, acid precipitation, melting of polar ice cover, shift in natural vegetation, manifestations of extreme weather conditions, etc.
ISRO, with strong constellation of geostationary and polar orbiting satellites, has been actively studying this phenomena related to climate research with a focus on specific indicators, like, glacier melt, desertification, land use and land cover change and agents, like, GHGs, aerosols, etc. A number of products are generated and being disseminated through NICES portal as shown in the below table.
