@korina Thank you Korina. I discovered the alternative in the form of a Plugin under the name Better Sounding. That should work for me.

Thanks for replying. I access the respective images of SO2, NO2 and PM2.5 every hour using the address mentioned before (for PM2.5) and then for a particular location (x,y) grid point on the image I get the RGB value, and then convert the RGB values to a concentration. In this way I can track the concentrations over time for a given location for research purposes. It's only when the PM2.5 image comes up the image is shifted to make way for the advertisement. I don't know why it only pops up when I access the PM2.5 image, but also why it happens when I access the website via Google Chrome via Python code, and it doesn't happen when I use the address by itself via Google Chrome
.

I have been accessing Windy.com capturing the current atmospheric conditions in the form of screenshots.
In a Python program I call:
"https://www.windy.com/-PM2-5-pm2p5?cams,pm2p5,31.199,73.652,7,i:pressure,m:exLaieX" and I always get the image including the What's New in Versions 47 advertisement, see image. However when I type the call in my browser is gives me the "clean" image without the Advertisement. see 2nd image. The advertisement is not the problem (I understand the need to advertise) if it would be superimposed on the image, but it moves the image across. Why would this be? The same call/request but a different result.

Thank you for that. Now I'll be on the lookout for these glitches.

Thank you for your reply. I have uploaded the images.

I have been monitoring SO2 pollution maps in our area for some time now. From time to time the SO2 values completely change from one hour to the next: i.e. see below! Within an hour the average value across the area goes from 25-30 mg/m2 at 3pm to < 1mg/m2 at 4pm and then the next hour it is back to 25-30 mg/m2 at 5pm. See the sequence below.

How is this possible? This seems to happen regularly in CAMS forecasting?
Why would this happen?
Any thoughts?

I'm trying to correlate your air quality information with what is happening on the ground. What is the time delay between the Copernicus satellite info actually capturing the image and you displaying it on your website? Thank you.

In the air quality forecast model CAMS 40 km is mentioned. Is that the spatial resolution of the forecast model?
Thank you.

Hi there how can I include active fires by default when I start up Windy.com? There does not seem to be a switch set in the URL, similar to i.e. "...i/pressure"

The slide down the LHS of the screen only has the day of the week and the date of the month.
I'm monitoring trends over time and the only reference to time on the screen is the day of the week and the date of the month.

Can you add the month and the year please, just as a numerical value that would be great?
