GES DISC

NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) completed ingest of the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) Cross-track Infrared Sounder (CrIS) Level 1B (L1B) Full Spectral Resolution product, which was produced by the Atmospheres Science Investigator-led Processing Systems and provided to GES DISC for distribution to the wider user community, albeit as a provisional release. In addition, Suomi NPP CrIS and Advanced Technology Microwave Sounder (ATMS) L1 data have been produced for 2014 to present and are ready for release pending receipt of dataset documentation from the provider. Data production for the entire record (2012-2016) continues.

NSIDC DAAC

NASA's National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has released Version 2 of Making Earth Science Records for Use in Research Environments (MEaSUREs) interferometric synthetic aperture radar (InSAR)-Based Antarctica Ice Velocity Map. Major updates to the dataset include data from 2011-2016 acquired from multiple International satellites. Landsat-8 optical imagery also was integrated into the data to improve coverage. The mosaicking method was updated to make best use of the large number of scenes used for the mosaic. In addition, several new parameters are included for assessing the quality of the data: the standard deviation of vx and vy for each pixel and count of scenes used for each pixel. Coverage increased from 95.1% to 99.6% and a reduction in error was achieved due to the utilization of more data.

ORNL DAAC

NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) released the collection 6 version of the Moderate Resolution Imaging Spectroradiometer (MODIS) subsetting and visualization tools https://modis.ornl.gov/cgi-bin/MODIS/global/subset.pl. Several new features have been added to this version of the tool:

• 14 MODIS Collection 6 land products offered
• Earthdata login implemented
• User order history (with Earthdata login)
• Improved performance
• Updated visualizations

PO.DAAC

NASA's Physical Oceanography DAAC (PO.DAAC) announced the release of the version 7.0.1 WindSat Level 3U (uncollated) Sea Surface Temperature dataset from Remote Sensing Systems. This dataset contains global near daily-coverage Level 3U SST with 25 km spatial resolution.
