@idefix37 Thank you for the explanation. I am using the mobile version only because I have it with me at the paragliding sites. I will test the desktop version to see the differences. For the mobile version a zoom from 0-3000 would help for the Aerologie. To choose Aerologie from the map ist OK by a resolution of some km.Screenshot_2021-02-20-10-00-51-168_com.windyty.android.jpg
The upper part of the screenshot is an example of the Aerologie / Sounding Forecast. Here you see "Zoom In" is from 0-7000m
