It's really really awesome!
Thank you Ivo and Windy Team for your hard work! You made a unique brand new extremely useful feature again! Congrats!
I think this satellite feature was waited by a huge amount of people, and now it became reality! From now everybody can use this eye-catching satellite feature and take care of their safety.
My question is the same as @Gkikas-LGPZ about the INFRA+ feature colour overlay.
The ozone layer is the part of the Earth's atmosphere that has the most ozone in it.
It's the atmospheric layer within the stratosphere, extending from a height of c. 20 to c. 30 km (c. 12 to c. 18 mi). The ozone layer protects living things from the harmful radiation of the sun. It absorbs dangerous ultraviolet radiation from the sun and serves to maintain the temperature of the atmosphere.
A dobson unit is the most basic measure used in ozone research. One Dobson Unit (DU) is defined to be 0.01 mm thickness at STP (standard temperature and pressure). Ozone layer thickness is expressed in terms of Dobson Units, which measure what its physical thickness would be if compressed in the Earth's atmosphere. In those terms, it's very thin indeed. A normal range is 300 to 500 Dobson Units (3-5 mm), which translates to an eighth of an inch-basically two stacked pennies.
In space, it's best not to envision the ozone layer as a distinct, measurable band. Instead, think of it in terms of parts per million concentrations in the stratosphere (the layer six to 30 miles above the Earth's surface).
The unit is named after Gordon Dobson, one of the first scientists to investigate atmospheric ozone.
NASA uses a baseline value of 220 DU for ozone. This was chosen as the starting point for observations of the Antarctic ozone hole, since values of less than 220 Dobson units were not found before 1979. Also, from direct measurements over Antarctica, a column ozone level of less than 220 Dobson units is a result of the ozone loss from chlorine and bromine compounds.
Ozone depletion describes two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events.
The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS). These compounds are transported into the stratosphere by wind after being emitted from the surface, mixing much faster than the molecules can settle. Once in the stratosphere, they release halogen atoms through photodissociation, which catalyze the breakdown of ozone (O3) into oxygen (O2). Both types of ozone depletion were observed to increase as emissions of halocarbons increased.
Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. The ozone layer prevents most harmful UVB wavelengths of ultraviolet light (UV light) from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn and cataracts, which were projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals. These concerns led to the adoption of the Montreal Protocol in 1987, which bans the production of CFCs, halons and other ozone-depleting chemicals.
@tz In this case maybe it would be better to have "Ceiling" word despite of the currently used "Cloud base", if the data is ceiling data that Windy got directly from ECMWF. Because Cloud base means the first cloud layer that can be also lower extent than 50%, in aviation it can be written like FEW (1-2/8 octas) / SCT (3-4/8 octas), in the METARs at the airports we can find these informations. Regarding the Ceiling, it can be from BKN (5-7/8 octas) to OVC (8/8 octas) types, because these two are covers more than 50% of the sky, so either BKN or OVC is depicted in a METAR this will be a "Ceiling". And this difference between Cloud base and Ceiling is very important according to my opinion.
I think maybe in this case it would not be so confusing, if you would change its name to "Ceiling" on Windy Meteogram.
What do you think about that? @TZ @Korina @ivo

Vote number 2: AROME
Windy has no such a good resolution model yet as AROME working on, so it could be very interesting, especially for mountainous areas to compare any other model's data to the new AROME model with (approx) 2 km resolution.
So my special vote is for AROME, because it's more interesting for me than the other models.
@deltaromeo
You can choose from several cloud layers: low/medium/high clouds, cloud base and cloud tops, or if you choose the main "Clouds" layer you will get a complex view of the clouds with the significant weather, such as rain.
You can see only the cloud coverage in percentage given.
I know that it's not the same that we use in aviation, where the cloud coverage is reported by the number of "oktas" (eights) of the sky that is occupied by cloud. But it's easy to compare the percentage of the coverage to how many oktas it can be.
The indication has 4 stages:
For example:
SCT050 - means that the scattered cloud has a cloudbase of 5000 ft.
BKN100 - means that the broken cloud has a cloudbase of 10000 ft.
Anyway you can activate the "Airports" overlay on the bottom of the right hand side of the website page (the airplane icon next to the "forecasted weather" cloud icon), so with this option you can see the airports (small circle signs, their colours are depends on the weather related flight rules (green - VFR, blue - MVFR, red - IFR, pink - LIFR) or if the airports hasn't have weather report services, their colours are gray), and of course their weather reports (METARs, TAFs) - in which you can read the actual and previous reports, Runways infos, Webcams and NOTAMs (big advantage is you can switch in the METAR and NOTAM menus from "raw mode" to decrypted view, so it helps you to understand what it means, plus in the NOTAM menu you are able to make each NOTAM report that you want to put into "read status", so it puts a check mark to that).
Some other useful abbreviations in aviation:
SKC - Sky Clear
NSC - No (nil) Significant Cloud
CB - Cumulonimbus (big, intensive cloud type through several athmosphere layers to high altitude, this is the most dangerous type of cloud with heavy rain, ice conditions and turbulence)
CU - Cumulus (generally low level puffy clouds, they can produce little or no precipitation, they can grow into the precipitation-bearing congestus or cumulonimbus clouds)
TCU - Towering Cumulus (significant, intense clouds with strong updrafts, turbulence and possibility of rain)
CAVOK - Ceiling and Visibility OK (a weather status report for pilots, when visibility is at least 10 km, there are no clouds below 5000 ft or minimum sector altitude (whichever is higher), and there is no current or forecasted significant weather such as precipitation.
I just tried it, It's cool!:)
(Btw I depicted the warm front by triangles by mistake, imagine it correctly with semi-circles..)

As my knowledge and experience, you can reach the thunderstorm layer by choose the "Rain, thunder" layer option, and beside this you can choose the unique "Thunderstorms" layer to see only the thunderstorm layer. If you choose the "Rain, thunder" uniform layer you will see a complex layer on the map, including: rain, snow and thunderstorm layers at once, which is nice to see in my opinion. The thunderstorm layer appears as little lightning signs, and the storm intensity is distinguishable by its size and luster. So in the case of light thunderstorm, it's small in size and appears as pale, transparent lightning signs; but in the case of strong severe thunderstorm, it becomes bigger in size and appears as shiny, luminous lightning signs.
I have found a severe thunderstorm in India, I made screenshots of both the two cases that I wrote: the complex layer "Rain, thunder" and the unique "Thunderstorms" layers.
I attach these screenshots here:

Pay attention to Marienka's posts for this problem!
I have found out the same issue at eastern part of Ukrain. It's clearly seeable that Windy integrated this radar area, because there is radar depiction in that area, same like on Rainviewer, I know that Windy have it as a source. But from Windy the light grey active radar range depiction is missing from the map unfortunately.

@wadoadi @windy1994 @Korina I did the same reset the Apple Watch app from the iPhone application. For others, if somebody would have the same issue, here you have a little help.
If the new features did not appear after you updated the iPhone Windy application you can follow the following steps to make the new functions available on your Apple Watch:
I hope it helps!:)
@zanep-0 I had the same issue like you, it did not appear after I updated the iPhone Windy application. But I was able to make it appear, follow the following steps to make the new functions available on your Apple Watch:

Windy changed it from cloud base to ceiling, but it is running under the same name on Windy. So the ceiling means > 50% of sky covered by clouds, in aviation it is higher than 4 octas, so it can be BKN = Broken or OVC = Overcast, where BKN = 5-7 octas, OVC = 8/8 octas fully covered.
And to answer your qestion, this parameter gives the height of ceiling in meters (m) or feet (ft) above the level of the model (ECMWF) orography, so it is AGL.
Read the corresponding article of Ceiling:
https://confluence.ecmwf.int//display/FCST/43r1+new+parameters%3A+Ceiling
But be aware of it, because of the ECMWF model has a 9km resolution, so it's sampling the terrain with 9 km steps. If you are planning around mountainous areas, you can't rely on it, do not use it for planning in such areas.

There was a general bug in currents feature, but it was fixed.
Read the according thread about that bug:
