  • MEaSUREs Greenland Ice Sheet Velocity Map from InSAR Data V002

    https://cmr.earthdata.nasa.gov/search/concepts/C3291179132-NSIDC_CPRD.xml
    Description:

    This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains seasonal (winter) ice sheet-wide velocity maps for Greenland. The maps are derived from Interferometric Synthetic Aperture Radar (InSAR) data obtained by the Canadian Space Agency's (CSA) RADARSAT-1, the Japan Aerospace Exploration Agency's (JAXA) Advanced Land Observation Satellite (ALOS), and the German Aerospace Center's (DLR) TerraSAR-X/TanDEM-X (TSX/TDX) satellites, as well as from the European Space Agency's (ESA) C-band Synthetic Aperture Radar data from Copernicus Sentinel-1A and -1B. See <a href="http://nsidc.org/data/measures/gimp">Greenland Ice Mapping Project (GIMP)</a> for related data.

  • MEaSUREs InSAR-Based Antarctica Ice Velocity Map V002

    https://cmr.earthdata.nasa.gov/search/concepts/C3291177469-NSIDC_CPRD.xml
    Description:

    This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, provides the first comprehensive, high-resolution, digital mosaics of ice motion in Antarctica assembled from multiple satellite interferometric, synthetic-aperture radar systems. Data were largely acquired during the International Polar Years 2007 to 2009, as well as between 2013 and 2016. Additional data acquired between 1996 and 2016 were used as needed to maximize coverage.

  • ESA Biomass Climate Change Initiative (Biomass_cci): Global datasets of forest above-ground biomass for the years 2010, 2017 and 2018, v2

    https://cmr.earthdata.nasa.gov/search/concepts/C2548142753-FEDEO.xml
    Description:

    This dataset comprises estimates of forest above-ground biomass for the years 2010, 2017 and 2018. They are derived from a combination of Earth observation data, depending on the year, from the Copernicus Sentinel-1 mission, Envisat’s ASAR instrument and JAXA’s Advanced Land Observing Satellite (ALOS-1 and ALOS-2), along with additional information from Earth observation sources. The data has been produced as part of the European Space Agency's (ESA's) Climate Change Initiative (CCI) programme by the Biomass CCI team. The data products consist of two (2) global layers that include estimates of:1) above ground biomass (AGB, unit: tons/ha i.e., Mg/ha) (raster dataset). This is defined as the mass, expressed as oven-dry weight of the woody parts (stem, bark, branches and twigs) of all living trees excluding stump and roots2) per-pixel estimates of above-ground biomass uncertainty expressed as the standard deviation in Mg/ha (raster dataset)This release of the data is version 2, with data provided in both netcdf and geotiff format. The quantification of AGB changes by taking the difference of two maps is strongly discouraged due to local biases and uncertainties. Version 3 maps will ensure a more realistic representation of AGB changes.

    https://cmr.earthdata.nasa.gov/search/concepts/C2548143582-FEDEO.xml
    Description:

    This dataset contains a time series of ice velocities for the Greenland margin from the PALSAR instrument on the ALOS satellite. It has been produced by the ESA Greenland Ice Sheet Climate Change Initiative (CCI) project. This dataset consists of a time series of ice velocity with yearly sampling, derived from intensity tracking of PALSAR data acquired between 20-12-2016 and 17-03-2011. It provides components of the ice velocity and the magnitude of the velocity. The data are provided on a polar stereographic grid (EPSG3413: Latitude of true scale 70N, Reference Longitude 45E). The horizontal velocity is provided in true meters per day, towards the EASTING(x) and NORTHING(y) directions of the grid; the vertical displacement (z), derived from a digital elevation model, is also provided. Please note that the previous versions of this product provided the horizontal velocities as true East and North velocities.Both a single NetCDF file (including all measurements and annotation), and separate geotiff files with the velocity components are provided. The product was generated by GEUS. For further details, please consult the Product User Guide (v2.0)Please note - this product was released on the Greenland Ice Sheets download page in June 2016, but an earlier product (also accidentally labelled v1.1) was available through the CCI Open Data Portal and the CEDA archive until 29th November 2016. Please now use the later v1.1 product.

  • ABoVE: Soil Drainage Maps from L-band SAR across Four Sites in Alaska and Canada

    https://cmr.earthdata.nasa.gov/search/concepts/C4289567589-ORNL_CLOUD.xml
    Description:

    This dataset provides four prototype soil drainage maps (relative soil drainage classes) across four study sites in Alaska and Canada including Bonanza Creek, AK; Hay River, Northwest Territories; Delta Junction, AK; and the Red Earth Creek, Alberta. The relative soil drainage classes were produced from an input time series of L-band HH-polarization SAR imagery from the ALOS-PALSAR or ALOS-2 PALSAR-2 (acquired via a JAXA data grant used for the Red Earth Creek Alberta site). The study sites had at least five ALOS-1/2 PALSAR growing season images and coincident in situ moisture data for multiple locations the scenes. Each map is relative based on different input months/years (dates and number of dates). The input data were acquired from repeat orbit/frames, radiometrically terrain corrected and stacked by site before applying a functional principal component analysis (FPCA). The scikit-FDA package in Python was used to apply FPCA to each time series of L-band SAR data. The outputs were coefficients and scores for the FPCA. Field data were used to test the coefficients and scores against in situ soil moisture. The second coefficient, was found to be significantly related to the coefficient of variation (CoV) of in situ soil moisture and was used to produce the maps. Once the relationships were established between the CoV of field plot data and the FPCA coefficient, the designated FPCA coefficient layers were used with a quantile classification of seven classes to output relative soil drainage. The data are provided in GeoTIFF format.
