Definition of Processing Levels

Level Contents
Level-1A Granule scene radiance data with the following information
  • Geolocation
  • Radiometric correction
  • Data quality including packet loss
Level-0 data are embeded so that the reprocessing of Level-1A from Level-1A is enabled
Level-1B Granule scene radiance data after the following processing
  • Radiometric correction
  • Geometric correction and resampling to Level-1B reference coordinates
In addition, geometric information for every spectral bands and calibration information are attached.
Level-2 Granule scene and global (tile) data of geophysical parameters derived from Level-1B or Level-2 products including global and tiled mosaic products with 250m, 1km, 4km (1/24deg.) spatial resolution
Level-3 Spatially and temporally averaged data of geophysical parameters derived from Level-2 and Level-3 products with the spatial resolutions of 1/24 and 1/12 degrees and temporal resolution of daily, 8-day, and 1-month
