Colour coding broken for cloud base and cloud tops - ECMWF
-
Look at e.g. 19th April 1200, S. Germany. It is all one colour, almost. Also the rain layer shows rain where the cloud base is showing 14000ft, which is nonsense.

This is because the color scales in Windy are smoothed. But you can customize them as you like. Even to get discrete scales. If you want to do it, just let me know. -
@idefix37 Yes someone on EuroGA pointed out that one can customise it. But it was OK before the latest UI change, so why was the mapping broken? It is a great deal of work to set up a transfer function for every layer one might want to use.

Are you sure the last UI update has broken the color mapping? I did not see any change.… to set up a transfer function for every layer one might want to use.
I don’t see what you mean.

@idefix37 See the URL I posted.

The last windy.com update has cleared most of the mappings between altitude and colour.
Maybe this was done for users who are sailing boats and don't need altitude data, but aviation users do need that data, in lots of steps. It used to be like that but somebody went in there and cleared the tables for cloudbase and cloud tops.
For cloudbase, one needs steps of about 200ft from 0 to 2000ft, then in say 500ft steps to 5000ft, then 1000ft steps up to 35000ft.
For cloud tops, one needs steps of about 500ft up to 5000ft and then 1000ft steps up to 35000ft.
It used to be something like that.
As the EuroGA.org thread shows, some expert users have produced their own mapping tables, but this is complicated.
