The skew-t at https://rucsoundings.noaa.gov/ allows a person to enter a lat/long instead of an airport. What I have not figured out is how to get the lat/long to work properly. I have entered a lat/long if different formats, but I have not gotten the right information back. I have been testing this by entering an airport location by its designator and by its lat/long. This should get me the same skew-t graphs, but so far I have not been successful. I have tried these 2 formats for Boulder Airport: “38.52, -105.59” and
If some has figured this out, please let me know how to make this work.
