Efficient downloading of S3 polar products

Hi Forum,

I’m not sure where to post this - it is a question about downloading Sentinel 3 data, so I don’t know if I should post this in STEP Forums or elsewhere. But until I know where else to post, I’ll ask here…

I’m downloading polar products over N. Greenland where overlapping orbits mean there are many scenes containing one location. I’d like to fetch the one image each day with the lowest solar zenith angle. Does anyone know how to do this efficiently? I can fetch all (4-6) images that cover one location and figure it out from the full product, but I’d like to save some bandwidth and time and not download that much data only to then discard ~80% of it.
