The GHRC DAAC’s Leigh Sinclair conducted a webinar titled “Striking New Spatial Bounds Using ISS LIS Data” on March 7, 2018. This webinar provided an overview of the ISS LIS Near Real-Time and Science Data, which allows for the study of lightning in hazardous weather over much of the Earth, highlighted ISS LIS lightning observations during the 2017 Atlantic Hurricane Season, and included a short demonstration on how these new ISS LIS data products can be plotted using Python. Dr. Michael Peterson, a Post-Doctoral Associate with the Earth System Science Interdisciplinary Center (ESSC) at the University of Maryland, also participated in this webinar describing how he uses these ISS LIS data.

The Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published a Python-based data recipe enabling users to generate vertical time-height plots of radar reflectivity measured by the High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) instrument during the Hurricane and Severe Storm Sentinel (HS3) airborne field campaign. The data recipe and associated code on the GHRC GitHub may be accessed here: https://ghrc.nsstc.nasa.gov/home/data-recipes/hs3-hiwrap-radar-reflectivity-profile-quick-view.

The NASA Global Hydrology Resource Center (GHRC) DAAC published a Micro Article about the Two-Dimensional Video Disdrometer (2DVD) instrument. A disdrometer is an optical device situated on a stationary ground station platform that measures properties of different hydrometeor (precipitation) types such as raindrops, snowflakes, and hail. This Micro Article and associated datasets at the NASA GHRC DAAC may be accessed here:https://ghrc.nsstc.nasa.gov/home/micro-articles/instrument-2dvd-disdrometer

 

The Global Hydrology Resource Center (GHRC) DAAC has published all four of the GPM Ground Validation NEXRAD Level III IFloodS datasets. The purpose of the IFloodS campaign was to help support the ground validation of the Global Precipitation Measurement (GPM). NEXt Generation Weather RADar system (NEXRAD) Level-II data were previously published.  These Level-III NEXRAD precipitation products were gathered from Unidata for four NEXRAD stations in the vicinity of the IFloodS campaign during March 29, 2013 through June 18, 2013. These datasets contain data files of digital instantaneous precipitation rate (DPR) and storm total accumulation estimates (DTA) in NIDS binary format. For a complete archive of data from each station beyond the IFloodS time period, please utilize the NOAA archives at Amazon Web Services and Open Common Consortium. See the NOAA website at https://www.ncdc.noaa.gov/data-access/radar-data/noaa-big-data-project for more information.

 

GHRC DAAC has published the NOXP IPHEx dataset: http://dx.doi.org/10.5067/GPMGV/IPHEX/NOXP/DATA101

The GPM Ground Validation NOAA X-band dual-Polarimetric radar (NOXP) IPHEx dataset consists of differential reflectivity, differential phase shift, co-polar cross correlation, radial Doppler velocity, spectrum width, signal index, melting layer index, reflectivity, drop size distribution, and rainfall rate observations, as well as other radar parameters, collected by NOXP mobile radar during the GPM Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign. The IPHEx field campaign occurred in the Southern Appalachians, spanning into the Piedmont and Coastal Plain regions of North Carolina. The NOXP radar, operated by the NOAA National Severe Storm Laboratory (NSSL), was positioned in the Pigeon River basin of the Great Smoky Mountains of North Carolina. NOXP data are available in netCDF-3 format for dates between April 21, 2014 through June 15, 2014. The dataset includes weather condition photos taken at the NOXP radar site in JPG format.
