Due to a lack of sounding data in the Himalayan region, we are using the Global Navigation Satellite System-Radio Occultation (GNSS-RO) to understand changes in vertical profile during extreme events—validation and data assimilation of RO data for high-resolution model simulation over the mountain terrain of the Himalayas.
Analysis of long-term solar weather and changes in the geomagnetic observation over the Indian region at the Indian Institute of Geomagnetism.
Precipitation variability on different time scales exhibits recurring patterns and quasi-oscillatory phenomena. Climate ENSO oscillations to precipitation have been analyzed over India and China (Asian Monsoon).
Study of carbonaceous aerosol (CA) emissions from open biomass burning over South Asia; Vertical and horizontal distribution of CAs from open biomass burning; Impact of CAs on radiative forcing and meteorological parameters quantified
The model can capture the seasonal trend over coasts and plains with the same parameterization and emission inventory set. In contrast, central Himalayan cities show an inverted trend during pre-monsoon and monsoon.
Under the Surat Clean Air Action Plan at WRI-India, we worked along with a construction data set to understand the emissions related to various types of construction in the Gujarat state of India.
