EOSDIS Data News - 08/10/2018


NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published the Ground Precipitation Measurement mission Ground Validation (GPM-GV) Doppler on Wheels (DOW) Olympic Mountain Experiment (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 OLYMPEX campaign. The DOW was deployed in the Chehalis Valley of the Olympic Peninsula, Washington, 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. These data are available in the radial RADAR CFradial netCDF-4 format from November 6, 2015 through January 15, 2016. Note that this new version of DOW OLYMPEX data was created to resolve a discrepancy between DOW and the NASA S-Band Dual Polarimetric Doppler radar (NPOL), which was also used in the OLYMPEX field campaign. A new and more appropriate calibration method was determined and the data reprocessed. Version-1 data were retired.


NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC) published the Advanced Microwave Scanning Radiometer for EOS (AMSR-E)/AMSR2 Unified Level 3 daily 6.25 km polar gridded 89 GHz brightness temperature dataset. This dataset uses the Japan Aerospace Exploration Agency AMSR2 Level-1R input brightness temperatures that are calibrated (unified) across the AMSR-E and AMSR2 Level-1R products. Data are mapped to a polar stereographic grid at 6.25 km spatial resolution and are available from 2 July 2012 through the present.

NSIDC DAAC published data through December 2017 for the dataset Making Earth System Data Records for Use in Research Environments (MEaSUREs) Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR, Version 1. This dataset, part of the MEaSUREs Program, provides velocity estimates determined from Interferometric Synthetic Aperture Radar (InSAR) data for major glacier outlet areas in Greenland beginning 1 January 2009. The InSAR Selected Glacier Site Velocity Maps are produced from the German Aerospace Center’s TerraSAR-X/TanDEM-X (TSX/TDX) image pairs.


NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) revised the North American Carbon Program (NACP) dataset NACP Multi-scale Synthesis and Terrestrial Model Intercomparison Project (MsTMIP): Global 0.5-degree Model Outputs in Standard Format, Version 1.0.This dataset provides global gridded estimates of carbon, energy, and hydrologic fluxes between the land and atmosphere from 15 Terrestrial Biosphere Models (TBMs) in a standard format. Model estimates are at monthly and yearly time steps for the period 1900 to 2010, with a spatial resolution of 0.5 degree x 0.5 degree globally, excluding Antarctica.

ORNL DAAC published “Observed and GEOS-5 Simulated CO Concentrations with Tagged Tracers for ATom-1”. The manuscript DOI in support of Strobe et al is at: http://doi.org/10.3334/ORNLDAAC/1604. Also, documentation and reviews are in progress for two additional Atmospheric Tomography Mission (ATom) manuscript datasets.
