Research Activities in Atmospheric Sciences Group are oriented towards better understanding of complex processes (physical, chemical, and dynamical) those are governing in Earth’s atmosphere. The atmospheric research group was established in year 2002 with a humble beginning of aerosols optical depth’s observations. Following this, observations of BC, ozone, CO, NOy, CH₄, SO₂ , NMHCs, CO₂, N₂O and the boundary layer meteorology (tower based) are also initiated. ARIES has also setup a facility of wind profiling using stratosphere troposphere radar (ST Radar), Lidar and balloon-borne observations of ozone.

Research Programs

Trace Gases: Surface observations of several trace gases, including greenhouse gases are being observed. Vertical distribution of ozone and meteorological parameters are being measured using balloon-borne sensors.

Boundary Layer Meteorology: ARIES hosts a meteorological tower for extensive observations of the boundary layer studies.

Dynamics: ARIES ST Radar and balloon-borne GPS radiosonde are being used.

Aerosols: Different physical, optical and chemical properties of aerosols are being observed. Aerosols scattering properties (Nephelometer) and aerodynamic particle size (APS) are being observed.
