METOP-B AVHRR Top-of-Atmosphere Reflectance Daily L3 Global 0.05 Deg. CMG
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/avhrr/m1_avh02c1.006
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.
Description
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.
