Hi, the path to OLCI products has to be the path to the SEN3 directory, not the Oa01_radiance.nc file.
Cheers, François

Hello, Apologies for the late answer, I have made some changes in example.py which was indeed based on an older version. The fix indicated by wxfei19whu should indeed fix the problem, at least you shouldn't receive an error such as : ImportError: cannot import name 'Level1' from 'polymer.main' These...

Hello Binbin,
Does the system run out of memory when this happens ? I suspect this may be the cause.
In this case you may also check in the script you are using to run Polymer, whether some objects are not released, thus cluttering the memory.
Cheers,

Hello, Apologies for the late answer. Which version of cython were you using ? The culprit commit concerns probably the modifications introduced for supporting cython>=3. However I have no experience of using polymer on Mac ; I don't know if using cython on this system may have an impact, and can no...

Hello, Apologies for the late answer and thanks for your feedback. This kind of algorithm unstabilities happen undersome circumstances, here most likely the presence of turbid waters and the grazing sun angles. The flags INCONSISTENCY+ANOMALY_RWMOD_BLUE are not recommended for systematical use for O...

Hello, The "CASE2" flag in Polymer is not dedicated to the detection of case 2 water, but is an internal flag which indicates if the algorithm works in "case 2 mode", which involves a second iteration round, and should be triggered mostly over turbid waters, but not always. This flag also does not i...

Hello,
Here the issue is not related to the use of the angle files, but to the file autodetection of landsat products in polymer_cli.py.
I have added a fix on github, hopefully it fixes this issue.
Cheers, François

Hello, please check my answer in the dedicated thread : viewtopic.php?f=7&t=256

Hello, Thanks for your feedback. This kind of errors may happen in some cases under which the algorithm may be unstable. The flag "ANOMALY_RWMOD_BLUE" (value 4096 - based on the detection of the difference between the model and the observation in the blue bands), then detects the resulting anomaly. ...
