Provided by the 20-channel GOES-8 and -10 sounders. Channels 10 through 12 are sensitive to lower to mid and upper tropospheric moisture. Channels 6 and 7 are slightly sensitive to atmospheric moisture and used to infer lower tropospheric moisture). The horizontal resolution is 10 km (at nadir), and the vertical resolution is about 3 km.

Provided by the 20-channel GOES-8 and -10 sounders. Channels 1 through 5 and 13 through 16 are sensitive to atmospheric temperature. Channels 7, 8, 17, and 18 are atmospheric window channels and used to infer surface temperature. The horizontal resolution is 10 km (at nadir) and the vertical resolution is about 3 km.

The 5-channel Advanced Microwave Sounding Unit-B (AMSU-B) and the 22-GHz channel (1) data from the AMSU-A provide microwave moisture data. Channels 2 through 5 of the AMSU-B are sensitive to atmospheric moisture. The horizontal resolution for the AMSU-B is 16 km (at nadir) and the vertical resolution is about 1.5 km. Channel 1 of the AMSU-A is sensitive to total atmospheric moisture, with a horizontal resolution of 48 km and a vertical resolution of about 5 km.

The 15-channel Advanced Microwave Sounding Unit-A (AMSU-A) provides temperature sounding. Channels 4 through 14 are sensitive to atmospheric temperature. The horizontal resolution is 48 km (at nadir), and the vertical resolution is about 3.5 km.

Infrared moisture data are provided by the 20-channel High-Resolution Infrared Radiation Sounder (HIRS). Channels 10 through 12 are sensitive to atmospheric moisture; channels 6 and 7 are slightly sensitive to atmospheric moisture. The horizontal resolution is 18 km (at nadir) and the vertical resolution is about 3 km.

Infrared temperature data are provided by the 20-channel High-Resolution Infrared Radiation Sounder (HIRS). Channels 1 through 7 and 13 through 17 are sensitive to atmospheric temperature. The horizontal resolution is 18 km (at nadir) and the vertical resolution is about 3 km.
