Error accessing CAMS files #16

Closed ftrastourlux closed 1 year ago

ftrastourlux commented 1 year ago

Hi, I get into trouble when trying to access CAMS files which are supposed to be located into : https://gws-access.jasmin.ac.uk/public/nceo_ard/cams/

SIAC tries to use these files using GDAL remote access using VSICURL with urls like : /vsicurl/https://gws-access.jasmin.ac.uk/public/nceo_ard/cams/2022_08_29/2022_08_29_aod550.tif but gdal.Open always failed.

I'm wondering if this url should still be valid or if there are alternate ways to download these data.

I'm working of the next release of https://s2gm.land.copernicus.eu/ and I really need to get SIAC working as the plan is to provide a way to provide L3 sentinel products (Temporal mosaics/Smooth RGB mosaics) based on SIAC processed L2A images (in addition to the current Sen2Corr L2A images).
