Amazing 👏👏👏

Muito bom trabalho. Eine super Arbeit

I think is important that a large organization (Copernicus)
trusts a small start-up (Windy)
to provide air quality data to the general public in a user-friendly way.
-
It is important for me to observe that NOx gases (air quality) occur
not only in large cities (because of high motor vehicle traffic).
COPERNICUS data shows high concentrations also along merchant ship routes
and airline routes (flight paths).
-
Also I want to inform the community that aerosol data (Atmospheric Optical Depth-AOD)
is highly correlated to reduced visibility (because of haze or dust).

Hi @Gkikas-LGPZ. I am Vincent-Henri and am in charge of CAMS. What you see on this layer is NO2 concentration at the surface. You rightly point to ship tracks over the Atlantic, Mediterranean. Over the Black Sea, these are also ship tracks, not flight paths. The lines that you point in Russia are motorways (M-11 between Moscow and St Petersburg or M-9 going westwards from Moscow to Latvia). Only a small fraction of NO2 emitted by aircraft make it to the ground directly: this is mostly near airports due to take-off & landing; NO2 emissions by aircraft at cruise level mostly get back to the ground through deposition of HNO3 and would not appear as lines at the surface. I hope this helps!

@vhp_cams
Thank you very much for the definitions!
Unfortunatelly, I haven't noticed that it is a surface concentration.
My fault.

I just strongly suggest to change colors of Ozone layers. High DU is now yellow which people read like BAD, while low DU are blue, which leaves people calm.

@ivo
There is "good" and "bad" ozone!
Near ground level ozone is an atmospheric pollutant
while stratospheric ozone (in the ozone layer) filters out sunlight
preventing damaging UV light from reaching the Earth's surface.

Great job! Amazing data
-
@Gkikas-LGPZ OK so which ozone we display now? The upper or lower one?
-
@ivo total column. For "every day use" I think UV radiation forecast is more useful as it takes into account not only ozone but also clouds and aerosol particles.

Standing Ovation from me to Windy & CAMS on their Merger!
I definitely will support & donate when I can to keep such an excellent platform on air! ;)

@Orion73064 Thank you!

@ivo We display total column of ozone, especially for monitoring of ozone holes = "the area where ozone columns are less than 220 Dobson Units (DU)". Antarctic ozone hole is seasonal. According to Copernicus, 2018's ozone hole "was one of the largest holes of recent years".

Could anyone explain why there is such a concentration of NO2 between the French coast and Corsica when selecting the CAMS 40km model compared to the CAMS EU 10km model? In the observed case the difference is about 10 times higher.
How can a model of low resolution (40km) show figures so high that a model of higher resolution (10km) does not detect. While the regional multi-models ensemble used by CAMS EU does not operate in the same way as the CAMS global model, these differences seems to be a bias.
We know there are many ferries and big cruise ships between the coast and Corsica, but what content of NO2 should be considered in this region?
(I have observed these big differences for several days now, and same issue in Algeria and Tunisia).

Hi,
It's obviously one of the most alarming statements I have ever read. I check the ozone forecast charts predictions daily. Here's the reference to the ozone layer monitoring and the graphics updated on a daily basis: https://atmosphere.copernicus.eu/monitoring-ozone-layer
