AVHRR Radiances - NASA

This dataset provides advanced scientific researchers a high quality Climate Data Record (CDR) of multiple radiance and reflective properties.

The Advanced Very High Resolution Radiometer (AVHRR) visible gains and offsets convert global area coverage (GAC) pixel level counts to radiances and are provided for each visible band encompassing TIROS-N, NOAA-6 through NOAA-19 and Metop-A and B platforms. The visible calibration coefficients are designed for cloud and land use; as well as radiation-imager-retrieval algorithms provide a consistent 35+-year climate quality sampling over time and across satellite platforms. The satellite-based visible calibration uncertainties provided, for use as a quality indicator of the calibration coefficients. The calibration coefficients reference to the Aqua-MODIS band 1 and 2 absolute calibration. Furthermore, the visible calibration coefficients derived, utilized regions over deep convective clouds, Sahara and Arabian Desert sites, as well as the Dome-C and Greenland pseudo invariant targets to compensate for individual site stability fluctuations over satellite lifetimes.
