@marekd I would say that there is bug in the API4 code! When using 'gh', 'pressure', 'temp', 'deg0' in W.store.set('isolines', 'x'), every isolines are changing and working nicely. But using W.store.set('isolines', 'off') after the above options, always getting some random isoline in the map!!! It's seem to be the most used isoline...

In higher level maps it would be ok to use gh-isolines, but then isolines had to be from same model than other data. Now gh comes always from ecmwf and it seems very confusing after couple of days ( when models start to differ). That's why it so important to get rid of "wrong" gh. Without any gh is better than wrong gh...

@marekd I meant. Is this wrong way to avoid showing any isolines?

W.store.set('isolines', 'off')

It would be great to have at least the CAPE of IconEu in paid API! Global CAPE would also be available in GFS model, but you don't have it either in windy.com. Have you ever thought to have CAPE of GFS in Windy?

@marekd thanks for your time! I've never coded before and everything is very new for me... I know your job is not to teach coding, but could tell me what is wrong in my JS:
W.store.set('isolines', 'off')

I have made everything straight to my public folder knowing nothing about debug console ;)

1. I use isobars (pressure isolines) most of my weather maps but want to make some higher-level maps with geopotential lines instead of isobars (or maybe without any isolines). Now it seems that all the geopotential lines have calculated from ECMWF and usually after one- or two-days those are looking just funny and confusing. Is it not possible to create geopotential lines from the chosen model?
2. If so, how can I exclude isobars from some maps. Now the API seem to make automatically isobars in all my maps if I don’t define any specific isolines.
3. Is it somehow possible to use the same functionality for isolines that is used in Windy.com (the box , where you can activate or deactivate different isolines)?
4. Is it possible to adjust particle speed and density in the paid API and do it only for one or two specific map?
5. Is it possible to change the interval of the isobars in the paid API. I would be interested to change interval when zooming in and out (I’m dreaming 5 mb interval in zoom level 1-4 and 1 mb interval in zoom level > 5 ;)
6. Is it somehow possible to adjust little less blurring for the isobars? The “kincks” of weather fronts is currently not detectable. It would be also possible to detect local wind effects from small “kincks” in the isobars… Of course, there must be some blurring, but in a meteorological sense it’s now little bit too much…
7. There is raster layers in precipitation map and cloudiness map. In precipitation map there is flakes and in cloud map there is precipitation. Is it possible to take these raster layers away or maybe make those working on/off…

1. Is it possible to get observation layers also to API4 (like in windy.com)? If it is, how?
2. Is it possible to load Pole Central maps to windy API (leaflet)?
3. Is it possible to make several maps that can be synchronized for timestamp? I mean that when chancing the time in one map, the time changes also in the all synchronized maps…

1. In Windy.com it’s possible to look CAPE, freezing level (deg0) and Snow cover also from IconEu model, but I couldn’t find those in Paid API4. Aren’t those included in API? Can I find the list of the exact names of different possible layers somewhere (I have use cape, deg0)
2. Is it now or later possible to get forecasted soundings from Icon model?

Really nice! Thanks again. I also like this more than Skew t-log p, which is too complicated in mobile. I hope this recent version will be at least one alternative in future and even the default. @ivo By the way the level indicator is not working in Firefox browser ( Chrome and Edge OK)

@arjannv Thanks so much!

I know all my rgb-values, but don't know how to code it in API4 ;)
