LEO Science Seminar on Tropical Cyclone Analysis and Forecasting

Galina Chirokova, Zhixing Ruan, and Mark DeMaria presented a virtual LEO Science Seminar on “Improving Tropical Cyclone Intensity Forecasts and Intensity and Structure Estimates Using Microwave Sounder Data”. The presentation discussed the history of estimating tropical cyclone parameters from microwave sounder data, the CIRA Operational Hurricane Intensity and Structure Algorithm (HISA), and application of HISA to new SmallSats data including TROPICS and Tomorow.IO microwave sounder data. In addition, several new experimental applications for forecasting tropical cyclone intensity and diagnosing storm type from JPSS data using artificial intelligence (JETClass model) were introduced. We also discussed a new Experimental LEO Tropical Cyclone web page that will be launched later this year. About 90 people were in attendance.
