Water vapor satellite imagery definition.

The module introduces the concept and function of the water vapor channel of satellite imagery and. This short course helps you combine the water vapour channel with your understanding of fluid dynamics to bring a new point of view to your meteorological. See the latest united states water vapor weather satellite map. This video describes how water vapor satellite imagery is used by meteorologist examples provided.

Water vapour imagery brings the shallow water model into plain sight. The ineractive map makes it easy to navitgate around the globe. 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. As with traditional ir imagery all radiation emitted below the effective.

National weather service weath. The wavelength spectrum used to detect water vapor is in the 6 7 to 7 3 micrometer wavelength range. Water vapor imagery is used to analyze the presence and movement of water vapor moisture in the upper and middle levels of the atmosphere. Water vapor imagery is created using a wavelength sensitive to the moisture content in the atmosphere.

Images a b and c are examples of visible and infrared and water vapor satellite images respectively valid for the same time. The upper and middle levels of the atmosphere are from about 650 mb to the top of the troposphere. Imagery and loops on this site are intended for informational purposes only they are not considered operational. This self paced interactive tutorial enables learners to discover practical uses for water vapor imagery from weather satellites.
