Re: They talked about HIRAD

"HIRAD is a hurricane imaging, single-pol passive C-band radiometer with both cross-track and along-track resolution that measures strong ocean surface winds through heavy rain from an aircraft or space-based platform.  Its swath width is approximately 60 degrees in either direction. There are two products: rain rate and wind speed."

I'm not familiar with it, but as far as I know NOAA still uses the SFMR. (which can have issues with rain) Not sure if they or anyone else has tested this though.
