EOSDIS Data News: February 16, 2018
NASA's National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has published the dataset MEaSUREs Greenland Quarterly Ice Sheet Velocity Mosaics from SAR and Landsat, Version 1. This dataset, part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, contains quarterly ice velocity mosaics for the Greenland Ice Sheet derived from Synthetic Aperture Radar (SAR) data obtained by TerraSAR-X/TanDEM-X (TSX/TDX) and Copernicus Sentinel-1A and -1B satellites, and from Landsat 8 optical imagery for years 2015 and 2016.
NSIDC DAAC has published the dataset MEaSUREs Greenland Monthly Ice Sheet Velocity Mosaics from SAR and Landsat, Version 1. This dataset contains monthly ice velocity mosaics for the Greenland Ice Sheet derived from Synthetic Aperture Radar (SAR) data obtained by TerraSAR-X/TanDEM-X (TSX/TDX) and Copernicus Sentinel-1A and -1B satellites, and from Landsat 8 optical imagery for years 2015 and 2016.
NSIDC DAAC has published data from December 2017 for the dataset MEaSUREs Greenland Image Mosaics from Sentinel-1A and 1B, Version 2. This dataset is part of the MEaSUREs Program.
NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the Atmospheric Carbon and Transport - America dataset (ACT-America): L2 In Situ CO2, CO, and CH4 Concentrations from Towers, Eastern USA. This dataset provides atmospheric carbon dioxide (CO2), carbon monoxide (CO), and methane (CH4) concentrations as measured on a network of 9 instrumented communications towers operated by the ACT-America project. Tower-based measurements began in early 2016 and are continuously collecting CO2, CO, and CH4 data to characterize ground-level (>100 m) carbon background conditions to support the periodic airborne measurement campaigns and transport modeling conducted by ACT-America.
ORNL DAAC published the Vegetation Collection dataset PhenoCam Dataset v1.0: Digital Camera Imagery from the PhenoCam Network, 2000-2015. This dataset provides a time series of visible-wavelength digital camera imagery collected through the PhenoCam Network at each of 133 sites in North America and Europe from 2000-2015. The raw imagery was used to derive information on phenology, including time series of vegetation color, canopy greenness, and phenology transition dates for the PhenoCam Dataset v1.0.
NASA's Physical Oceanography DAAC (PO.DAAC) ingestion testing was completed in preparation for release of a new dataset for Version 2.0 Rapidscat Level 2B Climate Ocean Wind Vectors dataset in 12.5km Footprints with sample data from the year 2016.
