Windy launches Satellite layer

Simply Fantastic

@setvak
thank you for the definitions.
Here in Windy (INFRA+) and for Mid-Latitudes, colored (blue) layer starts at 240K (-33C) ?
Personally, I preffer to start "colorize" IR images from -20C, which is a typical temp. for TCU starting to become a CB (IMHO) -
The reason for selecting 240K is that most storm anvils are at roughly this temperature (their warmest parts). When we were testing this color scheme about 12 years ago, we wanted to have the blue approx. outlining the storm anvils. Warmer temperatures depict also some of the lower, mid-level clouds, which we wanted to avoid.
-
@Gkikas-LGPZ It should be as @setvak wrote, i.e. range 240-200K, because we tried to create same palette like CHMI. Unfortunately it seems that there is still some bug, so the colour values are shifted. We will fix it.
I agree that it could be useful to shift colours for tropical/polar regions, but it could be misleading to use one colour for different temperatures in one picture. So this will probably remain constant. -
@TZ
You can try using some of the color palettes which are downloadable from the link above, or you can contact me directly by email. I would highly appreciate if the colors and their range can be the same (or very close) as on our website (http://portal.chmi.cz/files/portal/docs/meteo/sat/data_jsmsgview.html >> IR-BT), this way we would not confuse the public. EUMETSAT also uses the same color palette.
Re: (not) shifting the color range: this was rather a note that other weather services modify the range depending on their latitude or geographical region; for global images (as those used by you) this is impossible. BTW, the color scale usability also depends at the given location on actual height of the tropopause - with lower tropopause (e.g. polar air intrusions) the storm top temperatures are generally warmer, thus in those cases the storm tops appear in IR-BT images more blueish ... -
5 min step, as well as some next 60 min prediction, would be very usefull

Hi Windfolk
I use my ap for areas over the coast mostly. Great South Bay NY (southern Long Island)
the current Sat image is very dark in all the water areas which it is not in most other sat images There is a lot of nuance there that is lost...Good luck and thanks for your work! -
@setvak
@TZ
I fully understand the reason you use this color palette (240-200K).
Is it possible to have the ability to read (using the picker) the cloud top temperature ?
It would be very usefull for pilots (and aviation meteorologists) to know the temperature,
for computing the cloud top height. So, they will know (during the climb phase) the height they will be "on top".
Thank you again and congats for this new big feature. -

I don't think that prediction is available from EUMETSAT

WOW that's awesome!!!
THANKS to Ivo, Milan, Tomas, Martin, Jakub, Jindra, and all of the Windy Team!
Yeah, this layer is absolutely amazing. :) THX to WINDY Team
-
this came out phenomenal - really useful!
-
Damn this is so coool. Can't stop watching the animation of clouds, too hypnotizing _ And quality is awesome!
-
Hi
I have a suggestion
Merge the rain radar image with the satellite of clouds in one map -
Aw! Those of us in Talkeetna, AK, are in the "V" of no coverage :(
-
This is great
-
I Like the new edition to the site. Keep up the good work. I use this site more than any other to keep an eye on the weather and I used it to track Hurricane Michael. I live in FL thanks for the site. The Weather Chanel has removed their Hurricane Center from the web site.

I love it .... True Forecasting, Real Weather. That's Windy

@TalkeetnaAirTaxi That's what you get when you elect a cat as mayor ;-)
-
Thanks!
Will it be possible to show the cloudtop temperature when using the picker?BR Hans Christian

Sumptuously!!!
