 U.S.
Visible (Loop) |
N.M. Visible
(Loop)
- Visible satellite images of the contiguous United
States and New Mexico, updated approximately every 30 minutes, from
the Research Applications Program (RAP) of the National Center for
Atmospheric Research (NCAR). Visible satellites detect
reflected sunlight, thus clouds are brighter and land/water appear
darker in the image. Visible satellite images are not
available during the nighttime hours. |

Infrared (Loop) |
N.M. Infrared (Loop)
- Color-enhanced infrared satellite images of the
contiguous United States and New Mexico, updated approximately every 30 minutes
from the Research Applications Program (RAP) of the National Center
for Atmospheric Research (NCAR). Infrared satellites detect
the temperature of an object; warm objects emit more infrared
radiation than colder objects. The satellite measures this
energy difference and converts it to a temperature. High
clouds, which are colder, emit less infrared radiation and appear
green to bluish. Low clouds, which are warmer, emit more
infrared radiation and appear orange to reddish. During the
daytime, land will also be warm and appear red. |

 U.S. Water
Vapor (Loop)
|
N.M. Water Vapor (Loop)
- A color-enhanced, water vapor satellite image of the
contiguous United States, updated approximately every 30 minutes
from the Research Applications Program (RAP) of the National Center
for Atmospheric Research (NCAR). This image provides information
on the presence of water vapor in the mid-to-upper part of the troposphere by examining an infrared band of the radiation spectrum that is preferentially absorbed and emitted by water vapor. |
