    I am a Research Scientist with USRA working at NASA Goddard Space Flight Center. My work focuses on the development of the Integrated Multi-satellitE Retrievals for GPM (IMERG) gridded global precipitation product from the Global Precipitation Measurement (GPM) mission.

    Current Projects

    Improving the Lagrangian Interpolation Scheme in IMERG

    The Integrated Multi-satellitE Retrievals for GPM (IMERG) dataset is the gridded product from the NASA/JAXA Global Precipitation Measurement (GPM) mission. To achieve precipitation estimates globally at 0.1° every half-hour, IMERG combines intercalibrated precipitation retrievals from the GPM constellation of microwave sensors and uses Lagrangian interpolation and infrared observations to fill in the gaps.

    This project seeks to improve upon the Lagrangian interpolation method, first implemented in the CMORPH algorithm from NOAA/CPC, through data sources other than geostationary infrared observations.
