Description#

The API endpoint "/wthr/list/WeatherVariables" lists all currently available variables of a specific forecast model. The long name, the unit and the available levels (heights) are also specified for each variable.
Even if all available forecast models are listed and described with the corresponding variables of the weather API at Weather API - Variables. The API also reports the currently available variables for each forecast model itself.
This can be helpful when troubleshooting, for example.
