Observed GPCP precipitation trend (mm day-1 per decade) during (a) 1979-2014 and (b) 1979-2020. (c) AMIP6 and (d) CMIP6 historical full forcing simulated precipitation trend (mm day-1 per decade) during 1979-2014.

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.

Florida Flood Maps for Hurricane Ian

Hurricane Ian made landfall in Florida on the afternoon of 9/28/2022 as a massive Category 4 storm and brought record-setting winds. As of 10/4/2022, at least 105 people have been reported as casualties of Hurricane Ian, 55 of which in Lee County, Florida. Even more people are without power or their home. The NOAA STAR Flood team has produced VIIRS Flood maps, Sentinel-1 SAR Flood maps, and blended Flood maps to report the flood extent due to Hurricane Ian.
