Description 238-244
An indigenously designed High Energy Pulse LIDAR (HEPL) system was re-integrated and installed at ARIES, Nainital,
for probing the atmosphere and to analyse the Mie scatterers. After the characterization of the Photomultiplier tube and
Discriminator, about 50 quality checked valid measurements were investigated. Reasonably good signals were obtained upto
~2.5 km for 30 m altitude resolution, ~5 km for 150 m, and ~8 km for 300 m resolutions in the vertical, which were utilized
to investigate the aerosol and cloud profiles. The system was able to capture the clouds at various altitudes under different
atmospheric conditions. Elevated aerosol layers were also detected at about 3 and 3.5 km over the observation site. Such
unique measurements from the data void complex Himalayan terrain highlight the need for continuous monitoring of the
aerosol loading caused by transport of pollutants from continental locations and far-off distances that affect the air quality
and Himalayan glaciers as well.
