RESEARCH ACTIVITIES UNDER THE ATRF BRANCH

Trace gases

• In-situ measurements of the spatio-temporal characteristics of atmospheric trace gases O₃, NO_x, CO and trace gases CH₄ and CO₂ over Indian landmass and adjoining marine environments, using on-line gas analysers
• Balloon-based altitude profiling of Ozone
• Satellite-data based studies on the tropospheric distribution of trace gases and their variations over indian region
• Investigations on the role of mesoscale and synoptic scale meteorology on spatio-temporal distribution of trace gases
• Delineation of photochemistry and transport
• Model simulations of observed spatio- temporal features of trace gases
• Quantification of natural and anthropogenic contributions
• Assessment of radiative impact
