TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of SmallSats) satellite observations include microwave data at 12 different frequencies between 91.6 and 204.8 GHz. (Click here for a Satellite Book Club presentation on TROPICS). A TROPICS launch occurred from New Zealand in early May (link), boosting two satellites into orbit; a second launch is pending.
