Data Quality

Quality Assessment Files

For all AMSR-E products, each HDF-EOS file is accompanied by a Quality Assessment (QA) file. The QA files can be accessed through HTTPS or Earthdata Search. The contents of each QA file is unique to the product. The quality assessment is performed during standard product generation at the Global Hydrology and Climate Center (GHCC) - Science Investigator-led Processing System (SIPS). Should a product fail the assessment, the file is quarantined and the Team Leader Science Computing Facility is notified. After corrective action is taken, the file is reprocessed and forwarded to NSIDC for archive and distribution.
