Spectral ranges for the GOES-8 (top bars) and
GOES-M (bottom bars) Imagers. The GOES-8 bars
also represent GOES-9 through GOES-11, while the
GOES-M bars represent the imagers through GOES-P.
A sample high spectral-resolution earth emitted
spectra is also plotted.

GOES-12 Imager comparisons
The improved spatial resolution on the water
vapor images from GOES-12 are evident (4 km
detectors, as opposed to the 8 km detectors).
After accounting for spectral response
differences, the imager brightness temperatures
are similar to those from operational satellites.

Average satellite brightness temperatures
measured over the mountain wave signature region
were about 3 degrees K warmer on GOES-12 than on
GOES-10 or GOES-08. Similarly, using the GOES-12,
GOES-10 and GOES-08 weighting functions
calculated from the 19 September 0000 UTC
Albuquerque NM rawinsonde profile, the
theoretical water vapor channel brightness
temperatures at that point should have been about
3.5 degrees warmer on GOES-12 than on GOES-10 or
GOES-08.
