GHRC and the NASA GPM GV program

GPM-GV Field Campaigns

The NASA Global Precipitation Measurement Mission (GPMGround Validation (GV) program, as a member of the broader NASA Precipitation Measurement Mission, is providing ground and airborne precipitation datasets supporting physical validation of satellite-based precipitation retrieval algorithms.

Field research campaigns are essential for observing and measuring actual Earth system phenomena and validating computer models that simulate Earth systems. Ultimately, field data help improve the nation's ability to predict climate change and its impacts. The collaborative effort between Earth Scientists at the Global Hydrology and Resource Center (GHRC) and IT researchers has resulted in unique solutions to the collection, archive, management and dissemination of science data.

Focus on the measurement, physics, and improved prediction of heavy orographic snow in the PyeongChang region of South Korea. February - March 2018.

Hydrologic validation in extreme coastal and topographic gradients. Washington's Olympic Peninsula, Nov 2015-Feb 2016.

Characterized warm season orographic precipitation regimes, and the relationship between precipitation regimes and hydrologic processes in regions of complex terrain. North Carolina, Apr-June, 2014.

Studied characteristics, variability, and roles of rain and rainfall and other factors in flood genesis. Northeast Iowa, April-June 2013.

HyMeX aimed to improve the understanding, quantifying, and modeling of the hydrological cycle in the Mediterranean, with an emphasis on the predictability and evolution of extreme weather events, inter-annual to decadal (10 years) variability of the Mediterranean coupled system, and associated trends in the context of global change. NASA GPM-GV participation: Italy and France, Sept-Nov 2012.

Collaborative effort between the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility and NASA's GPM-GV program, to provide complete characterization of convective cloud systems, precipitation, and the environment. Ponca City, OK, April-May, 2011, partnered with DOE-ARM.

Addressed shortcomings in GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. Ontario, Canada, Jan-Feb. 2012, partnered with Environment Canada.

Collected microphysical properties, associated remote sensing observations, and coordinated model simulations of high latitude precipitation systems. Helsinki, Finland, fall-winter 2010, partnered with CloudSat.

The Canadian CloudSat/CALIPSO Validation Project (C3VP) is part of the international CloudSat program. With C3VP, the Meteorological Service of Canada (MSC), Environment Canada, has been performing extensive validation of the satellite products in the context of the Canadian climate. October 2006 - April 2007.
