GOES Imager Products
products generated from imager data
The imager detects different wavelengths
of energy through different
channels. This allows the imager to capture visible light, emitted long
wave radiation and other radiation wavelengths.
The imager has five
"channels" which monitor radiation at a specific
wavelength per given channel.
Channel and product descriptions are given below:
0.52 - 0.72 micrometers (visible) -
at 1 km, useful for cloud, pollution, and
haze detection and severe storm identification.

3.78 - 4.03 micrometers (short wave infrared window)
- at 4 km, useful for
identifying fog at night, discriminating between water clouds and snow or
ice crystal clouds, detecting fires and volcanoes, and
determining sea surface temperatures.

6.47 - 7.02 micrometers (upper level
water vapor) -
at 4 km, useful for
estimating regions of mid-level moisture content and advection plus tracking
mid-level atmospheric motions.

10.2 - 11.2 micrometers
(long wave infrared window)
- at 4 km, familiar to most
users for cloud-drift winds, severe storm identification, and location of heavy
rainfall.

11.5 - 12.5 micrometers
(infrared window more sensitive to water vapor) - at 4 km,
useful for identification of low-level moisture, determination of sea
surface temperature, and detection of airborne dust and volcanic ash.
