GOES Sounder Water Vapor (Upper, Middle, and Lower-Level)

Upper-Level Water Vapor

The central wavelength for this water vapor channel is at 6.5 µm, with a vertical weighting function peak at about 300 hPa, the highest of the three Sounder water vapor channels.

GOES Sounder Middle-Level Water Vapor

The central wavelength for this water vapor channel is at 7.0 µm, with a vertical weighting function peak at about 500 hPa, the middle of the three Sounder water vapor channels.

GOES Sounder Lower-Level Water Vapor

The central wavelength for this water vapor channel is at 7.4 µm, with a vertical weighting function peak at about 700 hPa, the lowest of the three Sounder water vapor channels.
