Hello everyone! I hope you are all well!
This is the first topic I have opened in this forum, so I apologize if anything is out of the ordinary.
I am here to report a problem and check if other users are facing the same difficulty when downloading global forecast data for fine particulate matter (PM2.5) together with the wind components (u10 and v10). Until 11/25/2024, I was able to download normally, obtaining a GRIB file with the three variables without any problems. However, since 11/28/2024, I have no longer been able to do the same procedure. This routine is essential for the preparation of air quality products in the Amazon.
As an alternative, I found a temporary solution: download the variables separately, creating a GRIB file with only the wind components and another with only PM2.5. Although this approach solved the problem momentarily, it is not ideal in an operational environment, as it requires more time and resources.
Here’s what appears to me when trying to download:
