Paper on calculating and using wind speed and direction from the new NASA CYclone Global Navigation Satellite System (CYGNSS) published in the Journal of Atmospheric and Oceanic Technology

To test the impact of new observations before such a satellite system is launched, observations like those from the satellite are created from a weather model. This study uses these “simulated” observations to learn how to […]
