  1. The Advanced Very High Resolution Radiometer (AVHRR) The AVHRR sensor measures radiance from the earth in five bands or channels with 1.1 km resolution at nadir. http://newton.gso.uri.edu/coastwatch/realtime_avhrr.html

  2. AVHRR Wavelengths

  3. How is SST Computed? • Convert radiance measured in the infrared channels to brightness temperature. • Use a multichannel technique to calculate SST to within ±0.5°C. • Cloud identification masks are created using visible and infrared channels with a series of spectral gradient, difference, and threshold tests.
