Climate.gov was not the centralized and only storage spot for climate data. There's petabytes of it all over the place.

You want data? https://www.noaa.gov/data or https://api.weather.gov/ or https://climatedataguide.ucar.edu/climate-data are a good place to start.

That only makes my question even more applicable... just with a wider scope.

As for your question: I personally don't want data, I want a service backed by sound data and expert validation+analysis.
