The NASA Global Hydrology Resource Center (GHRC) DAAC updated the GPM Ground Validation McGill Vertical Pointing X-Band (VertiX) Radar GCPEx dataset by adding GIF imagery. This dataset consists of radar reflectivity and Doppler velocity data collected by the Vertically Pointing X-band (VertiX) radar during the Global Precipitation Measurement (GPM) mission Cold-season Precipitation Experiment (GCPEx) field campaign in Ontario, Canada during the 2011-2012 winter season. VertiX can detect all precipitation targets and some ice clouds, as well as measure the Doppler velocity of precipitation targets. These measurements contributed to the overarching goal of GCPEx to collect various snowfall data for the improvement of GPM satellite winter precipitation estimates. These data files are...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GOES-R PLT Surface Radiance Ivanpah dataset. This dataset consists of surface reflectance and total optical depth data measured at Ivanpah Playa, Nevada during the GOES-R Post Launch Test (PLT) field campaign. The atmospheric measurements were made using an Automated Solar Radiometer (ASR), which tracks the sun throughout the day. Surface reflectance measurements were made using an ASD portable spectroradiometer and Spectralon reference panel. The GOES-R PLT field campaign took place from March to May of 2017 in support of...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Autonomous Parsivel Unit (APU) ICE POP dataset. This dataset was collected during the International Collaborative Experiments for Pyeongchang 2018 Olympic and Paralympic Winter Games (ICE POP) field campaign in South Korea. The two major objectives of ICE POP were to study severe winter weather events in regions of complex terrain and improve the short-term forecasting of such events. These data contributed to Global Precipitation Measurements mission Ground Validation (GPM GV) campaign efforts to improve satellite estimates...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Reference Precipitation IPHEx dataset. This dataset consists of 10 years (December 31, 2007-December 31, 2017) of hourly rainfall intensity at 1 km2 resolution over the core region of the Integrated Precipitation and Hydrology Experiment (IPHEx), that is centered in the Pigeon River Basin in North Carolina. The goal of the IPHEx field campaign was to evaluate the accuracy of satellite precipitation measurements and use the collected data for hydrology models in the region. Data files are available in ASCII format.

The NASA Global Hydrology Resource Center (GHRC) DAAC published the TCSP ER-2 Navigation Data. This dataset contains information recorded by the on-board navigation and data collection systems of the NASA ER-2 high-altitude research aircraft. In addition to typical navigation data (e.g., date, time, latitude/longitude, and altitude) it contains outside meteorological parameters such as wind speed, wind direction, and temperature. These data were collected during the Tropical Cloud Systems and Processes (TCSP) field campaign in July 2005, with flights based out of Juan Santamaria Airport in San Jose, Costa Rica. The main goal...
