The Campaign

The Integrated Precipitation and Hydrology Experiment (IPHEx) was a NASA-funded Global Precipitation Measurement (GPM) program Ground Validation (GPM GV) field campaign aimed at studying the relationship between warm season precipitation regimes and hydrologic processes in regions of complex terrain. The goal of IPHEx was to evaluate how well precipitation-monitoring satellite observations match the best estimate of the true precipitation measured at ground level and how that precipitation is distributed in clouds. The IPHEx deployment took place in the southern Appalachian mountains during May and June 2014 and utilized both ground and airborne instruments in complex terrain. The campaign also included a hydrologic applications component focused on Quantitative Precipitation Estimation (QPE) evaluations and impacts on hydrologic and water resources forecasts. Models were used to predict the quantity of water for rivers and aquifers, resource management, and flood and landslide prediction in the Upper Tennessee, Catawba-Santee, Yadkin-Pee Dee and Savannah river basins.

Additional Notes

OLYMPEX is one of the GPM Ground Validation field campaigns. OLYMPEX benefited from a collaboration with the NASA Aerosols/Clouds/Ecosystem (A/C/E) Radar Definition Experiment (RADEX)
