AVHRR Surface Reflectance

Sample image of NOAA CDR AVHRR Surface Reflectance product; it depicts land indications in shades of white and green across the globe.

This dataset provides scientific researchers a high quality Climate Data Record (CDR) of land surface reflectance.

Surface Reflectance provides a measure of the fraction of incoming solar radiation that is reflected from Earth's surface in two spectral ranges of the Advanced Very High Resolution Radiometer (AVHRR) sensors: red (around 640 nm) and the near infrared (around 860 nm). As a key variable, Surface Reflectance supplies the primary input for essentially all higher-level land surface geophysical parameters. The Surface Reflectance CDR delivers valuable surface information dating back to 1981 as a daily product on a 0.05° by 0.05° grid.
