Snow Microphysics image

The GHRC DAAC staff released the GPM Ground Validation GCPEX Snow Microphysics Case Study, a curated “virtual collection” dataset (DOI: This dataset represents a “golden case” from the GPM Ground Validation field campaigns — it comprises observations of a specific weather event from several different ground-based and airborne instruments. The data in this case study collection characterize the 3-D microphysical evolution and...

The GHRC DAAC published the GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) IPHEX dataset (doi: 10.5067/GPMGV/IPHEX/D3R/DATA101). This data was collected from May 3, 2014 to June 15, 2014 during the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) held in North Carolina. The D3R is a fully polarimetric, scanning weather radar system operating at the nominal frequencies of 13.91 GHz and 35.56 GHz covering a maximum range of 30 km. The GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) IPHEx dataset is available in netCDF format.

The GHRC DAAC has published dataset revisions for two merged satellite products from the DISCOVER MEaSUREs project:

RSS Monthly 1-deg Merged Wind Climatology netCDF V7R01

RSS Monthly 1-deg Microwave Total Precipitable Water netCDF V7R01

These data sets contain one-degree grids of monthly means, a 20-year climatology file, and a trend file containing the cumulative global trend map on a one degree grid and the time-latitude plot.  They...
