GHRC News

The NASA Global Hydrology Resource Center (GHRC) DAAC published the AMSU/MSU Day/Month Temperature Anomalies and Annual Cycle V6 datasets. These datasets consist of temperature anomalies and annual cycle temperatures derived from the Microwave Sounding Unit (MSU) and the Advanced Microwave Sounding Unit-A (AMSU-A) radiance data since January 1978. All products are derived for four bulk layers of the atmosphere: the lower stratosphere, tropopause, mid-troposphere, and lower troposphere. The datasets begin on January 1, 1978, and are still currently ongoing. The data are available in netCDF-4 and ASCII formats. In addition, the AMSU/MSU Day/Month Temperature Anomalies and Annual Cycle V5 datasets have been retired. Please now refer to the V6 datasets for the most up-to-date and accurate data.

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation CXSI Radar Imagery OLYMPEX dataset. This dataset contains radar reflectivity and precipitation rate images obtained from Environment and Climate Change Canada (ECCC)’s weather radar network during the GPM Ground Validation Olympic Mountain Experiment (OLYMPEX), which was conducted to validate rain and snow measurements in mid latitude frontal systems as they move from ocean to coast to mountains and to determine how remotely sensed measurements of precipitation by GPM can be applied to a range of hydrologic, weather forecasting, and climate data. These data are available as GIF images for November 19, 2015 through December 31, 2015.

Hurricane Michael is clearly visible in Worldview using LANCE NRT AMSR2 data. Please visit Worldview to follow Hurricane Michael and other storms using NRT AMSR2 data.

The NASA Global Hydrology Resource Center (GHRC) DAAC published the Hurricane and Severe Storm Sentinel (HS3) Cooperative Institute for Meteorological Satellite Studies (CIMSS) Tropical Overshooting Tops dataset. This dataset contains browse only data showing tropical overshooting tops derived from METEOSAT and GOES satellites for 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 browse only data files are available for dates between August 14, 2014 and October 3, 2014 at 15 minutes intervals in KML format. 

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 place during November 2015 through February 2016.
