  • CMS: Terrestrial Carbon Stocks, Emissions, and Fluxes for Conterminous US, 2001-2016

    https://cmr.earthdata.nasa.gov/search/concepts/C2082200618-ORNL_DAAC.xml
    Description:

    This dataset provides estimates of carbon pools, fluxes, and associated uncertainties across the contiguous USA (CONUS) at 0.5-degree resolution for all terrestrial land cover types. Carbon pools include labile carbon, foliar carbon, fine root, woody carbon, litter carbon, and soil organic carbon. Carbon fluxes include gross primary production (GPP), net primary production (NPP), net biome exchange, autotrophic respiration, and heterotrophic respiration. The modeled estimates are provided as monthly averages over the 16-year period, 2001 through 2016. The data were derived from the CARbon DAta MOdel fraMework (CARDAMOM) that included climate data, and above and below ground biomass maps of CONUS for the years 2005, 2010, 2015 and 2016 as input data sources to this model-data fusion framework. The input data were integrated into the CARDAMOM model to constrain on the terrestrial carbon and to specifically attribute changes of forest carbon stocks and spatial distributions of carbon emissions and removals across forested lands. United States Forest Service's Forest Inventory and Analysis (FIA) plot data were used to train models for the prediction of forest above-ground biomass (AGB).

  • Level 1.1 of PALSAR-2 (ALOS-2) Data Processing

    https://cmr.earthdata.nasa.gov/search/concepts/C1214561086-JAXA.xml
    Description:

    The state-of-the-art L-band Synthetic Aperture Radar (PALSAR-2) aboard ALOS-2 will have enhanced performance compared to ALOS/PALSAR. The PALSAR-2 is capable of observing day and night, and in all weather conditions. The ALOS-2 was launched by the H-IIA Launch Vehicle on May 24, 2014. Range and single look azimuth compressed data is represented by complex I and Q channels to preserve the magnitude and phase information. Range coordinate is in slant range. In the case of ScanSAR mode, an image file is generated per each scan. Resolution (m) Splotlight: 3*1 (Rg*Az) Ultrafine: 3 High sensitive: 6 Fine: 10 ScanSAR (Normal): 100 (3 looks) ScanSAR (Wide): 60

    Description:

    The state-of-the-art L-band Synthetic Aperture Radar (PALSAR-2) aboard ALOS-2 will have enhanced performance compared to ALOS/PALSAR. The PALSAR-2 is capable of observing day and night, and in all weather conditions. The ALOS-2 was launched by the H-IIA Launch Vehicle on May 24, 2014. Range and multi-look azimuth compressed data is represented by amplitude data. Range coordinate is converted from slant range to ground range, and map projection is performed.

  • Level 2.1 of PALSAR-2 (ALOS-2) Data Processing

    https://cmr.earthdata.nasa.gov/search/concepts/C1214561111-JAXA.xml
    Description:

    The state-of-the-art L-band Synthetic Aperture Radar (PALSAR-2) aboard ALOS-2 will have enhanced performance compared to ALOS/PALSAR. The PALSAR-2 is capable of observing day and night, and in all weather conditions. The ALOS-2 was launched by the H-IIA Launch Vehicle on May 24, 2014. Level 2.1 data is orthorectified from level 1.1 data by using digital elevation model. Pixel spacing is selectable depending on observation modes. Image coordinate in map projection is geocoded.

  • MEaSUREs Phase-Based Antarctica Ice Velocity Map V001

    https://cmr.earthdata.nasa.gov/search/concepts/C1699753973-NSIDC_ECS.xml
    Description:

    This data set, as part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, combines interferometric phases from multiple satellite interferometric synthetic-aperture radar systems to derive the first comprehensive phase-based map of Antarctic ice velocity. The precision in ice speed and flow direction over 80% of Antarctica is better than prior mappings based on feature and speckle tracking by a factor of 10. Phase-derived velocity mostly covers the years between 2007 and 2018, while tracking-derived velocity (for regions along the coasts) is mostly found in the years from 2013 to 2017. Additional data acquired between 1996 and 2018 were used as needed to maximize coverage. See <a href="https://nsidc.org/data/measures/aiv">Antarctic Ice Sheet Velocity and Mapping Data</a> for related data.
