Evaluation of Snowfall Retrieval Performance of GPM Constellation Radiometers Relative to Spaceborne Radars

Several current and former ESSIC/CISESS scientists are co-authors on a new paper in Journal of Hydrometeorology titled “Evaluation of Snowfall Retrieval Performance of GPM Constellation Radiometers Relative to Spaceborne Radars”. Former ESSIC scientist Yalei You was first author on the paper. Current ESSIC/CISESS scientists on the paper are Veljko Petkovic, Lisa Milani, John Yang, and Guojun Gu.

Observed Variability and Trends in Global Precipitation During the Satellite Era

ESSIC/CISESS scientists Guojun Gu and Robert Adler have a new article in Climate Dynamics that examines changes in global precipitation during the satellite (post-1979) era using the Global Precipitation Climatology Project (GPCP) V2.3 monthly precipitation analysis. They compared GPCP data with results from the Coupled Model Intercomparison Project phase 6 (CMIP6) and the Atmospheric Model Intercomparison Project (AMIP5) with the goal of improving current understanding of the effects of major physical mechanisms on precipitation change. They also aimed to assess the skills of current climate models and discover some clues for diagnosing possible limitations in observed precipitation.

ESSIC Scientists Contribute to State of the Climate Report

Several ESSIC/CISESS scientists have contributed to State of the Climate, the annual peer-reviewed summary of the global climate published by the American Meteorological Society. The recently-released State of the Climate in 2021 is the 32nd issue and features six chapters authored by dozens of international scientists. ESSIC/CISESS scientists Bob Adler, Jeannette Wild, Alexey Mishonov, Chelsea Parker, and Sinead Farrell contributed to the chapters “Global Climate”, “Global Ocean”, and “The Arctic”.
