The Advanced Microwave Sounding Unit-A (AMSU-A) is a 15-channel cross- track, stepped-line scanning, total power microwave radiometer. The instrument has an instantaneous field-of-view of 3.3° at the half-power points providing a nominal spatial resolution at nadir of 48 km (29.8 mi). The antenna provides a cross-track scan, scanning ±48.3° from nadir with a total of 30 Earth fields-of-view per scan line. This instrument completes one scan every 8 seconds.
