Thanks for your reply. I did some further investigation, see attached screen shot. Pic shows a sample location for today 13h00 LT. Graphical estimation from sounding, ECWMF) gives a thermal high of about 1500m at 23°, CCL 2841m , windy computation 1900m. Meteoblue (sorry to mention concurring source) provides ICON-D2 sounding which let me to estimate approx 1000m. Now am a little puzzeled but from experience I think the later is more realistic.

!

@idefix37 Affirmative, the cloud (airspace borders - symbols on a light yellow, green background are hardy visible. What a pity !

Thermal layer is an excellent feature ! Thanks to the windy team for the effort.

1. I use thermal layer with ICON-D2 model which gives an unprecedented granularity of the data. I understand ICON -D2 data are used to compute max climb altitude (AMSL). My experience flying a glider a consulting the thermal map is that the altitudes are far too optimistic and are rather 400-500m lower than computed. This can be evaluated and becomes evident when you crosscheck with barographic data of realworld flights of that day (WeGlide or OLC). Question, for calculation do you use simply Cumulus Condensation Level ?
2. In overlay to thermal map I put airspace plugin. How can I change the line color of the airspace display to make is more visible?
3. I changed the color scheme for altitude data. I would like to accommodate the color of the clouds for better visibility as well. How can I do this?
   Best regards

The display was wind map with pressure lines. I selected a location and scrolled to check the evolution in the future. The isobare picture changed as computed by the model. So everything fine. Now I changed to the actual sat picture which came up correctly. I like to see the pressure lines, so I selected them on, but what I got was not the acrual pressure lines but the pressure line according to the last selected time which I choose before on the wind page. Can be corrected by selecting whatever location and adjusting the time slider to the actual l time, but is very confusing at the first instance.

Thanks for your advice.

Excellent feature well done. To make it more usable for me I improved the resolution by choosing a more differentiated color scheme. The image includes wind information but not clear at which altitude. I assume ground level ?

I run Android app version in 16.11.5 but long press does not offer the sounding option, whereas on windy. Com internet page it does?
Any advice is appreciate.
Else super app! great job done 👍
