Wind Motions around the Tropical Cirrus Using Simultaneous Radar and Lidar Observations over Gadanki (13.45°N, 79.18°E), India

Comparison of aerosol extinction between lidar and SAGE II over Gadanki, a tropical station in India

An extensive comparison of aerosol extinction has been performed using lidar and Stratospheric Aerosol and Gas Experiment (SAGE) II data over Gadanki (13.5 N, 79.2 E), a tropical station in India, following coincident criteria during volcanically quiescent conditions from 1998 to 2005. The aerosol extinctions derived from lidar are higher than SAGE II during all seasons in the upper troposphere...

MST radar and polarization lindar observations of tropical cirrus

Significant gaps in our understanding of global cirrus effects on the climate system involve the role of frequently occurring tropical cirrus. Much of the cirrus in the atmosphere is largely due to frequent cumulus and convective activity in the tropics. In the Indian sub-tropical region, the deep convective activity is very prominent from April to December, which is a favorable period for the ...

Long-term trend analysis and climatology of tropical cirrus clouds using 16 years of lidar data set over Southern India

Sixteen-year (1998–2013) climatology of cirrus clouds and their macrophysical (base height, top height and geometrical thickness) and optical properties (cloud optical thickness) observed using a ground-based lidar over Gadanki (13.5 N, 79.2 E), India, is presented. The climatology obtained from the ground-based lidar is compared with the climatology obtained from 7 and a half years (June 2006–...

Tropical Composition, Cloud and Climate Coupling Experiment Validation for Cirrus Cloud Profiling Retrieval Using Cloudsat Radar and CALIPSO lidar

VHF/UHF radar observations of tropical mesoscale convective systems over southern India

Several campaigns have been carried out to study the convective systems over Gadanki (13.5 N, 79.2 E), a tropical station in India, using VHF and UHF radars. The height-time sections of several convective systems are investigated in detail to study reflectivity, turbulence and vertical velocity structure. Structure and dynamics of the convective systems are the main objectives of these campaign...
