Sentinel-5 nc files load problem in SNAP

I have had success in importing and processing S5 nc AI_AER files. But I get the following failure/error for the same dates S% CLD and SO2 nc files (on the latest SNAP on Windows 10):

I am accessing the S5 data from the Australian Sentinel data hub.

As an update - may I note that the S5 NO2 nc files are working fine importing into SNAP.

Further - the CH4 nc file ingests into SNAP fine too…

Thank you for reporting this issue.
Jira ticket SNAP-3601 created.

Dear Michael,

in general, SNAP does not fully support Sentinel 5p Level 2 data. Nevertheless, you can open the data using the generic NetCDF reader of SNAP, as you obviously do.

Concerning the crash: this was caused by a misformatted attribute:


This variable has an empty attribute “radiation_wavelength” which caused the crash.

I have updated the code to gently ignore that issue; the update will be released with SNAP 10.

With best regards,
