The group aims to study and diagnose the atmosphere through accurate, long-term, and comprehensive sensing using radio and optical waves both by active and passive means. Interests and fields of research of the group includes, study of Middle Atmospheric Dynamics with special emphasis on tropospheric and lower stratospheric structure and dynamics and on mesosphere and lower thermosphere. The group interests are in the study of   regional and global atmospheric boundary layer characteristics, global distribution of tropospheric water vapor, Indian Summer Monsoon, local, seasonal and global variability of gravity and planetary waves with special focus on source mechanisms, its impact on tropopause, low latitude mesospheric dynamics  with emphasis on mesospheric echo source mechanism, long term variability of background winds and temperature structure, mesospheric temperature inversion and the role of gravity wave-tidal interaction, to study long-term variability of the atmosphere, and interactions between waves at different time scales.
 
The group is also involved in the studies of Changes in middle atmospheric thermal structure and circulation due to major sudden stratospheric warming events, Relation among Sporadic sodium, Sporadic E, Field Aligned irregularities, and neutral winds, study of the characteristics of generation as well as the vertical propagation of internal atmospheric gravity waves in the lower and middle atmosphere

The group operates, maintains the following systems/ instruments and provides data (both raw data and analysed) to interested scientists.

ASDG utilizes both ground based systems mentioned above along with spaceborne measurements and has a plan to build Rayleigh Doppler lidar and an MF Radar to meet its scientific objectives. The group is actively involved in NARL’s SAFAR programme.

The group addresses the research problems with its band of five Scientists/Engineers :

The group has four research students right now. Qualified and interested candidates may approach for carrying out research in relevant fields.
