What I meant is clearly shown on screenshot below; in this case study, pressure and satellite images are not contemporary (12 h of difference!) and should not be displayed together:

satellite layer: real time observation, validity = (NOW-12h) pressure data layer: forecast model, validity= NOW (rounded to hours I guess)

@korina oh and sorry, one more suggestion before I forget. Not sure if this deserves a separate thread but it would also be extremely useful if there was an optional setting where alerts extend out to 7 or 10 days.

I know accuracy is lower at that type of range but if it was available as an option that could be turned on or off by premium or more advanced users (while keeping the default alerts to 5 days unless the user forces a change) and adding a disclaimer that skill will be lower, I think it would be a great addition.

@idefix37 Thanks! It's really cool. Just wanted to understand it. Thanks for the link.

Windy shows Copernicus fire monitoring data. This data is displayed in ‘near real time’ from satellite sensors as explained here:

https://atmosphere.copernicus.eu/fire-monitoring

But the interval update of this layer is 24h.

The difference with other fire monitoring satellites systems is that Copernicus provides an estimate of fire intensity when other sources only display the presence of fires.

As both Radar and Rain data layers are rasters, I'm not sure that rendering them together would be useful on UI map.

Moreover:

Radar data: real time observations in [Now-12h..Now], with validity step a couple of minutes Rain data: forecasts in [Now..Now+10d], with validity steps 1 hour thus these two data layers couldn't be contemporary (excepting maybe every full hour and only in the past)

Generally speaking, overlay two data layers is great when when a vector data layer (e.g. pressure isolines) is rendered over a raster data layer (e.g. Wind in color shading mode).

When you overlay two raster data layers, you have to disable the layer on the top in order to see the layer on the bottom. Or well to play a lot with new transparency color of each of the layers, which is not trivial (as both of them have blue palettes in this very case)...

@atalantia I want UV rating too! So important for me living in Australia. We have the depleted ozone above us. I’m a premium subscriber and having UV would make your app so much more complete.

@idefix37 said in Weather radar Windy and Latvia:

Sorry but for me it was not obvious which is radar from Latvia or from Estonia from your maps.

LV - Latvia
EE - Estonia
LT - Lithuania
It is sad.

@shaislet1 Thank you for your input, we will consider it.

@cvm87 We are glad to hear this! Hope you managed to stay away from the direct impact from the hurricane.

@dinytch

ppm means part per million
ppb means part per billion (and ppbv is just specifying by volume)
1 ppm = 1000 ppb
0.5 ppm = 500 ppb
Generally for gases ppm is expressed in volume and your standards are probably in ppm by volume. But you must check it.

@seba397
Radar imagery is not missing.
Windy shows the short range image
while NWS shows the long range.
IMO Windy's devs must take into consideration

@idefix37
Good afternoon! I am trying to understand what CO in PPBV means when applied to the norms in my country. We have:
rural areas - 332 ppm
small towns - 409 ppm
Big cities - 511 ppm.
now in my city 500 ppbv, if believe the map this is a serious excess, вut how to convert PPBV to ppm?
But when converted to ppm, it turns out that it is 0.5 ppm. Where is the error? Please help me to understand

@bruceha Hello, isolines currently cannot be saved, but we will think about it. Thank you for suggestion.

@tali Hello, each model updates at different time and each model also provides slightly different outcome. I recommend to check all of them first not based on update time.

@patapufq Dobrý den, děkujeme za feedback. Ve srovnání modelů je předpověď pouze 3h, přidání 1h pohledu zvážíme.

@shipwreckcity @vsinceac Hello, GFS model is updated again, the issue have been solved -

The local radar is not available

@hasan-20 Hello, I would recommend to have a look at https://support.google.com/maps/answer/2839911?hl=en&co=GENIE.Platform%3DAndroid

Vsinceac already post an example.

Those "deleted Posts" makes the forum very confusing, i have to scroll a lot to search topics.

Regards.

@emu-1 Thank you very much, we are happy to hear it!
