Advanced Very High Resolution Radiometer (AVHRR)

A sensor carried on board NOAA satellites used in meteorology and oceanography for measurements of cloud cover and sea surface temperature.

The sampling rate is 2048 pixels per scan, with a scan angle of 55.4° off nadir and a pixel resolution of 1.1 km over five spectral bands. The spectral windows of the five AVHRR channels are:
Channel 1: 580–680 nm

Channel 2: 725–1100 nm

Channel 3: 3550–3930 nm

Channel 4: 10.3–11.3 μm

Channel 5: 11.4–12.4 μm.
