What is a water vapor map?

Water vapor imagery is created using a wavelength sensitive to the moisture content in the atmosphere. 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.

What is water vapor satellite imagery?

WATER VAPOR IMAGERY: Water vapor satellite pictures indicate how much moisture is present in the upper atmosphere (approximately from 15,000 ft to 30,000 ft). The highest humidities will be the whitest areas while dry regions will be dark. Water vapor imagery is useful for indicating where heavy rain is possible.

How is water vapor imagery valuable?

Water vapor imagery is a valuable tool for weather analysis and forecasting, because it represents flow patterns of the upper troposphere. Water vapor is transparent to radiation at visible and 10-12 micron wavelengths. This is why visible and IR satellite imagery are used to observe surface features and clouds.

How is water vapor used in the atmosphere?

United States Colored Water Vapor Satellite. This image is taken using a wavelength sensitive to the content of water vapor in the atmosphere. Water vapor imagery is useful for both determining locations of moisture and atmospheric circulations that may affect your area.

What is the purpose of water vapor imagery?

This image is taken using a wavelength sensitive to the content of water vapor in the atmosphere. Water vapor imagery is useful for both determining locations of moisture and atmospheric circulations that may affect your area. We have updated our Privacy Policy and Cookie Policy .
