Satellite rainfall maps checked against floods (IFloodS campaign)

GPM Ground Validation Global Satellite Mapping of Precipitation (GSMaP) IFloodS V1
atmosphere NASA GHRC_DAAC Level 4 netCDF-4Binary
In plain English

What it measures. Hourly maps of how hard it was raining around the world during spring 2013, expressed as rainfall rate. It was gathered to support a flood-study field campaign in Iowa.

How it's made. Produced by the GSMaP project, which blends microwave readings from several satellites with infrared data from weather satellites to estimate rainfall.

How & where you'd use it. Used to study floods and to check how well satellite rainfall estimates match what actually happened on the ground during the IFloodS campaign.

Official description

The GPM Ground Validation Global Satellite Mapping of Precipitation (GSMaP) IFloodS dataset consists of rainfall rate estimates from the GSMaP project. The GSMaP global rain rate maps are derived by a collection of algorithms that utilize microwave (MW) radiometer data and geostationary Infrared (IR) data. The GSMaP Precipitation data product is provided on a 0.1 degree spatial resolution every hour and was made available for use during the Global Precipitation Measurement (GPM) Ground Validation Iowa Flood Studies (IFloodS) field campaign. These data are available in netCDF-4 and binary formats from April 22, 2013 through June 30, 2013. The near real-time GSMaP data can be obtained from the JAXA GSMaP web page.
