Great Lakes CoastWatch visible reflectance products are produced using two types of Advanced Very High Resolution Radiometer (AVHRR) satellite data. AVHRR channel 2 (reflected infrared at frequency 0.725-1.0 µm) and channel 1 (visible light at frequency 0.58-0.68 µm) from daytime passes of NOAA polar orbiting satellites are used to produce this data, which is useful in the detection of suspended solids and algal blooms in the Great Lakes.
