Satellite Instruments
The AMSU-B is a crosstrack, continuous line scanning, total power radiometer and provides measurements of scene radiance in five channels. The instrument has an IFOV of 1.1° (at the half power points). Spatial resolution at nadir is nominally 16 km (9.94 mi).The antenna provides a crosstrack scan, scanning ±48.95° from nadir with a total of 90 Earth fields-of-view per scan line. The instrument completes one scan every 2.66 seconds. The AMSU-B is designed to allow the calculation of the vertical water vapor profiles from the Earth’s surface to about a 200-millibar pressure altitude (12 km or 7.5 mi). The AMSU-B has also proven useful for the retrieval of ice water path (IWP) and ice effective diameter (De), which in turn are useful in providing information on rain rates.

REMARKS
Note that AMSU-B was replaced by MHS starting with NOAA-18 (similar instrument but with some minor differences) and AMSU-A and MHS fly on the METOP-A satellite
