Atmospheric Profiles from COSMIC Occultation Data
Listed in NASA Earthdata CMR
Using a radio occultation technique, scientists are able to use signals broadcast from Global Positioning System (GPS) satellites to retrieve profiles of bending angles, refractivity, temperature, pressure, and water vapor in the atmosphere.
Description
Also, profiles of electron density in the ionosphere. Such data are gathered and processed at the Constellation Observing System for Meteorology, Ionosphere, Climate (COSMIC) Data Analysis and Archive Center (CDAAC) in Boulder, Colorado.
Various products are produced including atmospheric profiles starting from near Earth's surface to the height of the satellites at 800 kilometers (500 miles) above the Earth surface. At this time only atmospheric profiles of bending angle, refractivity, and dry temperature are available. As we receive more data this archive will continue to expand to include more variable profiles.
