      Hi,

      I am looking to use Windy API in my application. I want to include wind speed at different altitudes, but I am finding the 'levels' difficult to interpret.

      Does anyone have any guidance on how to convert the levels described in the API (also below) into metres above mean sea level at latitudes of approx. 50deg N?

      The docs state the following:
      *An array of geopotential values (the default value is ["surface"]). It is applicable for the following parameters: wind, dewpoint, temp, gh and rh. For all other parameters the default value surface is used instead.

      The allowed values are: surface, 1000h, 950h, 925h, 900h, 850h, 800h, 700h, 600h, 500h, 400h, 300h, 200h, 150h*

      Thanks!

        1000h stands for 1000 hPa etc
        To convert hPa to altitude (standard atmosphere)
        https://www.brisbanehotairballooning.com.au/wp-content/uploads/PressuretoAltitudeConversion.pdf

        e.g. 500h=500hpa=18289ft= 5574m
