On Extreme Winds at L-Band with the SMAP Synthetic Aperture Radar

Blog Article

In this letter, we discuss some observations of the Soil Moisture Active Faber Hood Cocktail Wall 80 Cm Black Glass 220-240V 330 0572 379 Passive (SMAP) mission’s high-resolution synthetic aperture radar (SAR) for extreme winds and tropical cyclones.We find that the L-band cross-polarized backscatter is far more sensitive to wind speed at extreme winds than the co-polarized backscatter and it is essential to observations of extreme winds with L-band SAR.We introduce a cyclone wind speed retrieval algorithm and apply it to the limited SMAP SAR dataset of cyclones.We show that the SMAP SAR instrument Ski de fond - Equipement - Skis - Enfant - Combi is capable of measuring extreme winds up to the category 5 (70 m/s) wind speed regime providing unique capabilities as compared to traditional scatterometers with C and Ku-band radars.
