Multi-satellite rainfall estimates (IPHEx campaign)

GPM Ground Validation TRMM Multi-satellite Precipitation Analysis (TMPA) IPHEx V7
atmosphere NASA GHRC_DAAC Level 3 netCDF-4
In plain English

What it measures. Maps of precipitation every three hours during a 2014 field campaign in North Carolina's mountains, showing how much rain fell across complex terrain.

How it's made. A slice of the TMPA product, which merges microwave and infrared satellite data with ground rain-gauge readings and other rain products like TRMM's precipitation radar.

How & where you'd use it. Helped researchers study mountain rainfall and how it drives water flow through the landscape, and serves as a reference for comparing rainfall estimates.

Official description

This GPM Ground Validation TRMM Multi-satellite Precipitation Analysis (TMPA) IPHEx dataset is a subset of the TMPA 3B42RT gridded precipitation product selected for the time period of the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) held in North Carolina during May 1, 2014 to June 15, 2014. The goal of IPHEx was to characterize warm season orographic precipitation regimes and the relationship between precipitation regimes and hydrologic processes in regions of complex terrain. This dataset contains 3-hourly, 0.25 degree maps of precipitation derived using microwave (MW), infra-red (IR), surface precipitation gauge measurements, and other rain products that include the TRMM Precipitation Radar (PR) data. The IPHEx TMPA product is available in netCDF-4 and binary formats.
