GHRC News

On Monday, 5/7/2018, Deborah Smith and Tammy Smith of GHRC presented the GHRC data recipes and micro articles, online content available to users that connect information and data. They described the design process used to develop new types of micro articles and the iterative process that occurs between designer and outreach team members.

GHRC has published the GPM Ground Validation National Mosaic and Multi-Sensor QPE (NMQ) System IFloodS (http://dx.doi.org/10.5067/GPMGV/IFLOODS/NMQ/DATA101). This dataset contains quality control products, real time rain rate estimates, hourly precipitation rate estimates, and three-dimensional reflectivity products. These data products are also referred to as Multi-Radar Multi-Sensor Precipitation Reanalysis for Satellite Validation (MRMS) product and were created using the NOAA NMQ System which ingests Weather Surveillance Radar 88 Doppler (WSR-88D) radar data, Rapid Update Cycle (RUC) model analysis fields, and Hydrometeorological Automated Data Systems (HADS) gauge data. The files provided in this dataset are from the NMQ system output obtained during the GPM Iowa Flood Studies (IFloodS) field campaign that occurred throughout Iowa. These data are available in ASCII, netCDF-4, and binary formats for the dates between April 1, 2013 through June 30, 2013.

The GHRC published the GPM Ground Validation Snow Depth Monitoring System OLYMPEX dataset (http://dx.doi.org/10.5067/GPMGV/OLYMPEX/SNOWTUBE/DATA101). This dataset consists of snow depth, temperature, and relative humidity measurements which were collected using snow depth poles, time lapse cameras, temperature/relative humidity sensors, and manual snow surveys.  This dataset was collected during the GPM Ground Validation Olympic Mountain Experiment (OLYMPEX) held on the Olympic Peninsula in the Pacific Northwest of the United States. The analyzed data files are available in netCDF-3 data format.  The dataset includes the individual camera photos of snow poles taken hourly during the field campaign, provided as JPG images.  There are up to 3 cameras/poles per study site location.  In addition, a Microsoft Excel data file contains results of a manual snow survey taken on the specific days of the Airborne Snow Observatory OLYMPEX overflights.  In total, measurements contained in this dataset extend from September 5, 2014 through August 20, 2016, but the primary field campaign data were collected during the fall 2015 to spring 2016 time period.

The GHRC published the GPM Ground Validation Airborne Snow Observatory (ASO) OLYMPEX dataset (http://dx.doi.org/10.5067/GPMGV/OLYMPEX/LIDAR/DATA101). This dataset consists of snow depth, bare earth surface, land surface classification and a Red, Green, Blue (RGB) composite  image, provided at 3 m spatial resolution during the GPM Ground Validation Olympic Mountains Experiment (OLYMPEX) field campaign held in the Pacific Northwest. These data were collected by a Riegl Q1560 scanning LiDAR and an ITRES CASI-1500 imaging spectrometer, both part of the NASA Airborne Snow Observatory (ASO), during two separate periods, February 8-9, 2016 and March 29-30, 2016.  A previous September 2014 flight was used to obtain no-snow measurements used for deriving snow depth. The data are provided in GeoTIFF format.

 
The GHRC published the GPM Ground Validation NASA S-Band Dual-Polarimetric (NPOL) Doppler Radar Wallops Flight Facility (WFF) dataset (http://dx.doi.org/10.5067/GPMGV/WFF/NPOL/DATA101). This dataset consists of rain rate, reflectivity, Doppler velocity, and other radar measurements obtained from the NPOL doppler radar positioned at the Wallops Flight Facility (WFF) in support of the Global Precipitation Mission (GPM). NPOL was developed by  scientists at WFF and is a fully transportable and self-contained S-band (10 cm), scanning dual-polarimetric Doppler research radar that was placed near Newark, Maryland between GPM GV missions. Data files are available from December 6, 2013 thru April 28, 2017 in Universal Format (UF), with browse files in PNG format containing images of corrected radar reflectivity, differential reflectivity, specific differential phase, co-polar correlation, and Doppler velocity images.  Data are tarred into daily collections of files and zipped for storage and quick download. It should be noted that this dataset does not have continuous data. Data are missing for various dates that are listed in the user guide.
