Water Vapor Satellite Definition

See the latest united states water vapor weather satellite map.
Water vapor satellite definition. The ineractive map makes it easy to navitgate around the globe. A satellite instrument tuned to such a wavelength can determine the temperature of these gases which emit the radiation. 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. The upper and middle levels of the atmosphere are from above the troposphere there is very little moisture.
Water vapor is a relatively common atmospheric constituent present even in the solar atmosphere as well as every planet in the solar system and many astronomical objects including natural satellites comets and even large asteroids. Since water vapor is present everywhere water vapor satellite images show air motions in the atmosphere even in areas of blue skies with no clouds. Notice the area of spin over seattle and the ripples over northern california and oregon. One such gas is water vapor.
Imagery and loops on this site are intended for informational purposes only they are not considered operational. Water vapor channel satellite imagery water vapor imagery analysis for severe weather water vapor imagery and pv. 14 at 6 05 a m. This web site should not be used to support operational observation forecasting emergency or.
Recognition and impact of vorticity maxima and minima in satellite imagery other resources to explore. The purple areas show more water vapor while red areas show less. Water vapor imagery is created using a wavelength sensitive to the moisture content in the atmosphere. Edt 1005 utc nasa s aqua satellite passed over tropical storm karina in the eastern pacific ocean and found highest concentrations of water vapor brown and coldest.
Near a wavelength of 6 5 microns water vapor. Likewise the detection of extrasolar water vapor would indicate a similar distribution in other planetary systems.
