The NASA Global Hydrology Resource Center (GHRC) DAAC published a new Micro Article about the Olympic Mountains Experiment (OLYMPEX) field campaign. A micro article is a short, interesting document that brings together data and key science concepts. The OLYMPEX was a Global Precipitation Measurement (GPM) ground validation field campaign that  consisted of a wide variety of ground instrumentation, radars, and multiple aircrafts all which monitored the weather conditions and rainfall dropped by oceanic storm systems as they approached and traversed the Peninsula and the Olympic Mountains. The intensive observing period took...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the Tropical Cyclone Intensity (TCI) Hurricane Imaging Radiometer (HIRAD) dataset. This dataset was created for the TCI field campaign from August 30, 2015 through October 23, 2015. The goal of the TCI field campaign was to improve the prediction of tropical cyclone (TC) intensity and structure change. The specific focus was to have an improved understanding of TC upper-level outflow layer processes and dynamics. These Hurricane Imaging Radiometer (HIRAD) data were obtained from the instrument onboard the NASA WB-57 aircraft flow...

The NASA Global Hydrology Resource Center (GHRC) DAAC now has the Lightning Imaging Sensor (LIS) on TRMM Science Data and the LIS on TRMM Backgrounds datasets available in netCDF/CF format, as well as the historical HDF-4 format.  TRMM LIS was used to detect the distribution and variability of total lightning occurring in the Earth’s tropical and subtropical regions. The LIS Science Data consist of lightning and lightning density measurements and are used for severe storm detection and analysis, as well as for lightning-atmosphere interaction studies. The LIS instrument makes measurements during both day...

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Naval Research Laboratory (NRL) Near-Real Time Rain Rates IFloodS dataset. This data product was created for the GPM Iowa Flood Studies (IFloodS) field campaign from April 23, 2013 through June 30, 2013. The IFloodS field campaign was a ground measurement campaign that took place in eastern Iowa. The goals of the 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. This NRL real time rain rates data product was produced using the Probability Matching Method with rain gauge, Defense Meteorological Satellite Program (DMSP) F15 Special Sensor...

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...

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...

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...
