I don't think the request for "climate change layer" would be related to current weather forecast models (i.e. data layers for fire, hurricane, air quality, extreme forecast or yet fires).
I think it is rather about anomalies of observerd or forecasted values related to climatological normals...
At this stage, climatological normals (generally computed over 30 years period), are not currently available on Windy (while they could and they should imho.).

Such a remark would legitimately raise a couple of questions: where, when, which forecast data layer, how wrong, why worst (compared to what)?

GRIB2 files of new GFSWave forecast model are available for free here since a couple of months (take files named [...].global.[...] for worldwide coverage).
Pay attention to new download policy, too: no more than 120 hits per minute ftp get queries (including HEAD queries), otherwise your IP would be blacklisted by NCEP/NOAA servers.

See a very similar complain in this post. You should also provide more details (e.g. screenshots) in support to your remarks...

Now, with screenshot above (many thanks!), I understand much better your problem.

This is weird, as for me this layer works perfectly at any moment for the same area and map scale (screenshot below - cannot go back in the past at same date/time as on your screenshot). That data layer may be empty at bigger map scale though (i.e. no rain is forecasted).

Maybe your internet access is cut off by moments? Did you tried on other device with different internet access? Do you use the most recent version of Edge? Did you tried on a different web browser, e.g. Chrome?

You could also watch if following type of query returns something - with web browser in debug mode (F12) - when you select some new date/time on the time bar for that layer: https://ims.windy.com/ecmwf-hres/2021/08/03/06/257w3/3/0/rainlogptype2-surface.png?reftime=2021072512.

Otherwise, you should wait for help from Windy support team.

See this post, it provides short description of each available data layer (the list was dressed 5 years ago).

For each selected data layer, the UI control "i" (screenshot) provides more details.

Nope, it is not a weird weather phenomenon, it is just about weird data sent by the weather radar "SADAW". The same radar images are also weird on all other sites which display it.

You should compare with satellite images over the same period: one can see that nothing significant happens over that area...

Weird radar images appear from time to time, for different reasons; see this or this post for more details.

AROME model grid provides values every 1.3 km, thus a 50 km wide map has enough values to interpolate... then Point values on map intepolate very well at such a scale, even for model grids with less resolution. This is why I think the reasons to don't display data layers at big scales is rather related to server performances than protecting base map details (the aim of Windy maps is weather, not base maps). I hope Windy staff could tell more about this...

For Radar data layer, just select the goat, known to run faster than turtles and rabbits:

Windy support team acts during office hours Central European Time (UTC+2h in Summer); you should get help on Monday morning.

OK, now it is more clear; obviously, weather data layers are removed at big map scales (excepting wind particles and isolines of atmospheric pressure layers), see also this related post. When the map width covers about 50 km on Earth:

• only default layers (wind particles and atmospheric pressure isolines) are displayed on map
• even if UI controls for data layers are still enabled (selection of model, parameter, level, etc.)
• point location control (click on map) displays interpolated values of currently selected data layer

I don't know more. I think Windy staff would be able to explain the reason to do so; it could be related to the max. map scale for which map tiles are pre-computed on server side, or to the poor interpolation results which can be obtained at such a scale from models grids with big cells.

Small circles should be for "Calm Winds"; see more details on wind barbs in this post or this one.

The images you posted don't appear above; try the alternate control (one of the two available on screenshot), and/or reducing the size of the image files, and/or providing images as a web link (i.e. loading them on any 3rd party web site).

No, nobody asked you where you live; what I said above was just that screenshots of Windy maps on any locations where you cannot get the wheather info you expect to, could help to understand your request.

And no, I never tried get rid of any monkey; I just tried to help, as your original remark "Windy does not show rain" was not enough clear (at least to me). Windy doesn't show only wind, which is just the default data layer on maps. Users can select one of the several dozens of data layers provided by Windy, including rain and temperature; they are all available on the right side UI controls on the web browser. For the full list of data layers on Windy maps, see this post (which is 5 years old; now there are even more data layers).

Satellite images (which are just one of the dozens of available data layers) cannot provide rain info; they rather get the temperature of clouds, thus they are real time observations of their altitude and dynamics (presence of clouds doesn't does not imply that it rains). You can see rain (if any) on Radar data layer, as well as on corresponding weather forecast models and/or weather stations layers. To prove that "Windy does show rain", one can check these many discussions on this topic...

I hope the reason about cancelling your subscription would be not related to the fact that one Windy user tried to get more info in order to be able to answer your request (thus to help you, without being paid by Windy to do so).

Sorry, I'm not Premium, but I guess the right side option would make the deal.
At least it says "Cancel Anytime"; anyway, 1.6€ for 1 month is much less than the price of one bus ticket in Paris (:oj)---

Послушайте, если вы действительно хотите пожаловаться на надежность моделей прогноза погоды, пожалуйста, используйте ссылки, предоставленные Windy для каждой модели (скриншот), и объясните ученым, что они отстой.

Пожалуйста, поймите, что Windy не рассчитывает прогноз погоды; он просто отображает некоторые из лучших моделей прогноза погоды в мире. Прогнозирование погоды не является точной наукой; оно прогрессирует каждый год, и я полагаю, что каждый текущий год намного лучше, чем любой другой предыдущий год.
