The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Reference Rainfall Data Product IFloodS dataset. This dataset contains hourly rainfall accumulation estimates over central and northeastern Iowa for the period of 1 May to 16 June, 2013. This product is created by combining ground-based radar estimates collected for the Iowa Flood Studies (IFloodS) campaign. The goals of the IFloodS campaign were to collect detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars and to simultaneously collect data from satellites passing overhead. The data are available in gzipped ASCII files.
The NASA Global Hydrology Resource Center (GHRC) DAAC published the Hurricane and Severe Storm Sentinel (HS3) Statistical Hurricane Intensity Prediction Scheme (SHIPS) Intensity dataset. This dataset was obtained from March 18, 2014 through September 30, 2014 during the Hurricane and Severe Storm Sentinel (HS3) field campaign. Goals for the HS3 field campaign included assessing the relative roles of large-scale environment and storm-scale internal processes, addressing the controversial role of the Saharan Air Layer (SAL) in tropical storm formation and intensification, and the role of deep convection in the inner-core region of storms. The SHIPS model provides tropical storm intensity forecasts for the Atlantic Ocean and the eastern and central North Pacific Ocean storms and invest areas.  SHIPS uses GOES infrared imagery as input to the systems.  These SHIPS data are available in ASCII format.

The NASA Global Hydrology Resource Center (GHRC) DAAC just published a new ESRI Story Map titled ‘Dizzy the Disdrometer: A story of how Dizzy the Disdrometer participated in the Global Precipitation Measurement (GPM) Ground Validation field campaigns’. This story map is a fun and interactive way to learn about the disdrometer instrument, the GPM Ground Validation project, GHRC, the different field campaigns performed during the project, and where the reader can find these data. This story map can be found at

Leigh Sinclair and Rebecca Kollmeter from the Global Hydrology Resource Center (GHRC) DAAC participated in the University of Alabama in Huntsville’s (UAH) Week of Welcome, where they described the DAAC and handed out materials for the interested students. The UAH students enjoyed the lightning visualization from the GHRC DAAC. 



DOW at OLYMPEXThe NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Doppler on Wheels (DOW) OLYMPEX V2 dataset. This dataset was obtained by a dual-polarization and dual-frequency X-band mobile radar operated by the Center for Severe Weather Research (CSWR) during the Olympic Mountain Experiment (OLYMPEX) campaign. The DOW was deployed in the Chehalis Valley for the OLYMPEX field campaign with the goal of obtaining radar reflectivity and Doppler velocity observations in order to better understand the orographic enhancement of precipitation during frontal passages over mountain ranges. The DOW radar uses two 250 kW transmitters with a measurement range of roughly 60 km. These data are available in CFradial netCDF-4 format from November 6, 2015 through January 15, 2016. It should be noted that this new version of DOW OLYMPEX data was created due to a discrepancy between DOW and the NASA S-Band Dual Polarimetric Doppler radar (NPOL), which was also used in the OLYMPEX field campaign. A new and more appropriate calibration method was determined and the data were reprocessed.
