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

Summary:  The NASA CYclone Global Navigation Satellite System (CYGNSS) measures wind speed, but not direction, at the ocean surface. 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 … Continue reading Paper on calculating and using wind speed and direction from the new NASA CYclone Global Navigation Satellite System (CYGNSS) released online in the Journal of Atmospheric and Oceanic Technology

Paper on combining satellite data and data from the Global Hawk aircraft to improve forecasts published in Weather and Forecasting

Summary: Because satellites are observing the weather all the time, there are almost always satellite data available around hurricanes or tropical cyclones (TCs). On the other hand, Hurricane Hunter aircraft can only reach TCs when the storms are near land and when airplanes and crews are available. When Hurricane Hunter missions are planned, the regular … Continue reading Paper on combining satellite data and data from the Global Hawk aircraft to improve forecasts published in Weather and Forecasting
