GOES Sounder
radiometer for producing atmospheric vertical profiles
The GOES Sounder is a 19-channel discrete-filter radiometer
covering the spectral range from the visible channel wavelengths
to 15 microns. It is designed to provide data from which
atmospheric temperature and moisture profiles, surface and
cloud-top temperatures and pressures, and ozone distribution can be deduced
by mathematical analysis.

GOES Mission Overview
It operates independently of and
simultaneously with the Imager,
using a similarly flexible
scanning system.
The sounder's multi-element detector array assemblies simultaneously sample
four separate fields or atmospheric columns.
A rotating filter wheel, which brings spectral filters into the
optical path of the detector array, provides the infrared channel definition.
