OC-SMART Sentinel-2

Dear SNAP Community Plugins
I’m trying to run the atmosphere correction OC-SMART in L1C-MSI Sentinel-2A. However, I’m getting this message regarding the ancillary data for ozone.
“Unable to download ancillary data for ozone. Using climatology data as backup…”
If I click “OK” the AC doesn’t work properly.
I don’t know how to fix it. Please, could someone help me to solve this issue?
Many thanks for considering my request.

Hello Amália,

even though a plugin for SNAP is provided, OC-SMART is not a Community Plugin in the narrow meaning. Community Plugins are listed on this page: SNAP Community Plugins – STEP (esa.int)
So, I think the developer of OC-SMART do not monitor this forum.
It seems they do not provide user support at all. At least it is difficult to find a contact point.
Maybe you can reach out to Knut Stamnes who is the director of the laboratory which developed OC-SMART. Knut Stamnes - Stevens Institute of Technology

Just a hint from my side. The plugin is made for SNAP 7. This is what is mentioned in the user guide. Maybe OC-SMART wasn’t updated for the latest changes of the S2-MSI format.
