NOAA to launch satellite with NASA to improve hurricane predictions

US: To improve hurricane predictions, a new satellite will be launched soon in October by NOAA and NASA’s join efforts. The satellite is being launched with the intention to getting more expansive hurricane predictions, revealed a study led by researchers at Pennsylvania State University, including meteorologist Fuqing Zhang, regarding GOES-R, a geostationary satellite.

"For decades, geostationary satellites such as the GOES series have been the primary tool to monitor severe weather like storms and hurricanes in real time," noted Zhang. "They have helped people see what's going on in the present, but, until now, we as a community have not been able to tap into these resources to guide us to predict future severe weather."

Geostationary satellites are a type that remain in orbit above a fixed Earth location. They take images of meteorological information, including cloud formations. GOES stands for Geostationary Operational Environmental Satellites and the program is operated by the National Oceanic and Atmospheric Administration with NASA contributions.

However, "brightness temperature" is part of the currently collected data, demonstrating radiation quantities emitted by Earth objects and existing in the atmosphere at different degrees of infrared.

"At some frequencies, water vapour absorbs moderate amounts of radiation passing through it, at other frequencies it absorbs most of that radiation, and at other frequencies it absorbs hardly any at all. Unlike water vapour, clouds strongly absorb radiation at all of these frequencies," noted Eugene Clothiaux, study co-author and a meteorologist at Penn State.
