I have more than 8 years of experience in the field of ABL explorations and hydrological cycle processes using ground-based Microwave Radiometer Profiler (MRP), radiosonde observations, data from meteorological sensors, satellite, and reanalysis. I am competent in operating the radiometer, balloon-borne radiosonde and meteorological sensors and can carry out lab and field experiments using them. I am also adept in handling and analysing data from these instruments including their quality control procedures. I have worked on various observational campaigns as briefed in my resume which has given me the confidence and comfort to work independently as well as part of a team. I have great experience in analysing huge data (both instrumental and satellite). Since I have extensively investigated the land atmosphere interactions using ground based remote sensing techniques and in-situ observations, I strongly believe that I can carry out the research work in the advertised field and provide immediate and meaningful contribution at your lab.

Along with instrumental and field expertise, I have also experience in model simulations using AR-WRF and I am strong in programming using MATLAB, and am familiar with Python. I am well-versed in the Windows operating system and have also worked in the Linux (Ubuntu) platform.

Research Highlights

  • Multi-frequency microwave remote sensing of the Earth’s atmosphere for temperature, humidity, clouds and precipitation.

  • Evolution of the Atmospheric Boundary Layer (ABL) at diurnal and seasonal scales at different geographical locations that include coastal, complex terrains, and continental and the forcing mechanisms responsible for the variations.
