Atmospheric aerosols are an important entity and are the subject for research in current scenario due to their diverse physical and optical properties. In my thesis work, we have reported the findings on the intriguing aspects of boundary layer and wave induced aerosol dynamics over a high altitude site in central Himalayan region. We have used the Doppler Lidar (DL) and other collocated instruments along with satellite datasets during Ganges valley aerosols experiment (GVAX) 2011-2012 to understand the morphological characteristics of aerosols, long-range trasnport and associated dynamics over the site. Also, we have estimated cloud base height over this site for the first time using Doppler lidar and other collocated instruments and found reasonably good correlation of cloud base heights estimated with different methods and instruments.

Now, we would like to extend our work by validating the ground based instruments (Doppler Lidar, Ceilometer etc) with different satellite datasets (space borne Lidar satellite (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO)), MODIS, AIRS, CLOUDSAT) over a complex topographic region in the central Himalayan region. During my doctoral work, we have also attempted to understand the short period and long period modulations which could provide a clue of understanding additional heating rates in the atmosphere in episodic events. Now, we will also take long term datasets of different ground based and also global datasets to understand the affect of planetary scale wave modulations over our region. Apart from this, a ST-Radar facility is also coming up at ARIES which will provide high vertical and temporal resolution tropospheric wind measurements which will be used to understand lower tropospheric dynamics over Central Himalayan region.
