Description

The product description in this landing page is designed to provide information about the AVHRR Top-of-Atmosphere Reflectance Daily L3 Global 0.05 Deg. Climate Modeling Grid, version 6.0 product from the Advanced Very-High-Resolution Radiometer (AVHRR) instrument on-board the ESA/EUMETSAT's MetOp-B satellite platform.

The Long-Term Data Record (LTDR) is a NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) project at the LAADS DAAC that produces and distributes a set of land surface climate data records (CDR). CDRs provide a 40+ years' time-series of well-calibrated, consistent set of daily measurements that are used to analyze and understand global climate variability and change. The LTDR project serves as an important bridge in that it helps connect data derived from the NOAA and European Space Agency's Advanced Very-High-Resolution Radiometer (AVHRR) to the EOS Moderate resolution Imaging Spectroradiometer (MODIS), the Suomi National Polar-orbiting Partnership (SNPP) Visible Infrared Imaging Radiometer Suite (VIIRS), and Joint Polar Satellite System (JPSS) VIIRS missions.

The AVHRR Top-of-Atmosphere Reflectance Daily L3 Global 0.05 Deg CMG product provides the following measurements: Top-of-atmosphere reflectance for band-1 (640 nm) and band-2 (860 nm), Brightness temperatures for band-3 (3.75 µ), band-4 (11.0 µ), band-5 (12.0 µ) besides quality assurance (QA) information and angle information for Solar Zenith, View Zenith, and Relative Azimuth angles. It also provides the scan timeframes as well.

The LTDR v6.0 AVH02C1 collection's record is available for the following timespans for each satellite-instrument source:

  • MetOp-B: 2013-016 to present [Launched in September 2012]
  • NOAA-19: 2009-151 to 2022-143 [Launched in February 2009]
  • NOAA-18: 2005-182 to 2009-365 [Launched in May 2005]
  • NOAA-16: 2000-306 to 2007-365 [Launched in September 2000]
  • NOAA-14: 1995-001 to 2000-305 [Launched in December 1994]
  • NOAA-11: 1988-313 to 1994-365 [Launched in September 1988]
  • NOAA-09: 1985-004 to 1988-312 [Launched in December 1984]
  • NOAA-07: 1981-175 to 1985-033 [Launched in June 1981]
