It explained that the NOAA “uses the 23.6-24 GHz spectrum band for microwave sensor-based remote sensing of atmospheric levels of water vapor, which is the single most impactful data stream for accurately forecasting weather. This data is used by NOAA’s National Weather Service, the National Aeronautics and Space Administration (NASA), and the Department of Defense (DOD), in addition to the broader international weather community.”
Without this data, the letter said, forecasting accuracy “would be reduced to the accuracy of forecasts produced in the 1970s.”
Very interesting!
Which seems about right. I did not know that.
