# Satellite Instrument/Band

GOES-10 consists of a Sounder and Imager. The Sounder has 18 infrared spectral channels and the Imager has 4.

# Atmosphere

There are four atmospheric profiles used to calculate weighting functions here. They represent different temperatures and total column ozone and water vapor. Each profile consists of temperature, ozone, and mixing ratio at 101 pressure levels.

# Zenith Angle

Satellite viewing angle is varied in increments of 5 degrees. The default 0 value is a nadir view. Given the same atmospheric profile, the brightness temperature measured by a satellite will vary by zenith angle (colder or warmer, depending on the band).

# Column Moisture %

Each of the four atmospheres used in these examples has a certain amount of total column water vapor. By default this is left unaltered (100%) but it can be seen decreased in increments of 10% all the way down to 0% to demonstrate the effects of moisture on the different channel weight functions and calculated brightness temperatures.

# Skin Temperature Adjustment

The skin temperature used by default in these atmospheres is the temperature in the lowest level of the atmospheric profile. This is adjusted up and down to demonstrate the effects of skin temperature on the weighting function and brightness temperature.
