NRT AMSR2 DAILY L3 12.5 KM TB AND SEA ICE CONCENTRATION POLAR GRIDS V0

Version 0 NRT
  • Abstract
    The Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument on the Global Change Observation Mission - Water 1 (GCOM-W1) provides global passive microwave measurements of terrestrial, oceanic, and atmospheric parameters for the investigation of global water and energy cycles. Near real-time (NRT) products are generated within 3 hours of the last observations in the file, by the Land Atmosphere Near real-time Capability for EOS (LANCE) at the AMSR Science Investigator-led Processing System (AMSR SIPS), which is collocated with the Global Hydrology Resource Center (GHRC) DAAC. The NRT AMSR2 Daily Level-3 gridded 12.5 km sea ice product includes brightness temperatures at 18.7 through 89.0 GHz and sea ice concentration. Data are mapped to a polar stereographic grid at 12.5 km spatial resolution. Sea ice concentration and brightness temperatures include daily ascending averages, daily descending averages, and daily averages. Data are stored in HDF-EOS5 format and are available via HTTP from the EOSDIS LANCE system at https://lance.nsstc.nasa.gov/amsr2-science/data/level3/seaice12. If data latency is not a primary concern, please consider using science quality products. Science products are created using the best available ancillary, calibration and ephemeris information. Science quality products are an internally consistent, well-calibrated record of the Earth's geophysical properties to support science. The AMSR SIPS plans to start producing initial AMSR2 standard science quality data products in 2016 and they will be available from the NSIDC DAAC. Discontinuation Notice: The Version 0 LANCE AMSR2 Sea Ice datasets are being replaced with LANCE AMSR2 Sea Ice Version 1 datasets that use the latest AMSR-U2 Sea Ice algorithms. Please transition to using these new version 1 datasets. We will discontinue the product generation of Version 0 LANCE AMSR2 Sea Ice data on October 31, 2018.
