The module introduces the concept and function of the water vapor channel of satellite imagery and.
This video describes how water vapor satellite imagery is used by meteorologist examples provided.
For water vapor imagery right the effective layer is defined as the highest level of appreciable water vapor whose radiation can be detected by the satellite.
In this imagery bright blue and white areas indicate the presence of high water vapor or moisture content whereas dark orange and brown areas indicate little or no moisture present.
Imagery and loops on this site are intended for informational purposes only they are not considered operational.
A the visible image depicts clouds stretching from the gulf of mexico northeastward into canada.
Thus even though water vapor is an invisible gas at visible wavelengths our eyes can t see it and at longer infrared wavelengths the fact that it emits so readily between roughly 6 and 7 microns means the radiometer aboard the satellite can see it.
Water vapor imagery is used to analyze the presence and movement of water vapor moisture in the upper and middle levels of the atmosphere.
