Is there a certain height that the measurements for windSpeed are taken at? I am using a function for calculating an approximation of wet bulb globe temperature that requires the 2m wind speed, but can use a helper function to estimate the 2m wind speed given the wind speed at a different height.

Thank you for your help

Not official, but the NWS uses data from a variety of places. Some places might be higher or lower. I think you might want to try to Google the name of your weather station so you can locate its elevation or some pictures.

The observation endpoint metadata includes the elevation of the station, but to @KTibow 's point they are land-based. So the height is merely the height of the object (building, tower, etc.) that the observation equipment is attached to.

We are working on efforts to add IWXXM observations to the API.

I’ve found this API from the USGS very accurate, parameters are EPSG:4326 not EPSG:3857<https://en.wikipedia.org/wiki/EPSG_Geodetic_Parameter_Dataset>. https://nationalmap.gov/epqs/pqs.php?x={Longitude}&y={Latitude}&units=Feet&output=json Joe Perkins
