These data are already consumed operationally by the major global weather modeling centers - e.g., check out the AMDAR [1] or ACARS programs. There are commercial agreements which restrict third-party access to these data in real-time, but they are widely disseminate with a 24-48 hour lag in the observational archives that NOAA curates for weather modeling.

These data are a very important input for operational weather forecasting. On a global basis, we've seen how losing these data during the pandemic due to reductions in air travel decreased forecast model skill [2]. Furthermore, ACARS profiles derived from aircraft landing at airports where severe weather is expected are regularly used to complement SPECI weather balloon launches.

Thank you for the info, I am glad to hear that the data is being collected and used. Getting it from raw ADS-B reports makes all fields available without the lag (and thus more useful for weather reporting and forecasting), but the recorded data is definitely good to have!
