Hello,
Polymer has indeed been applied to GOCI data in the past, as mentioned on the homepage, but the algorithm has been entirely rewritten and currently, GOCI data are not supported. The GOCI reader would have to be rewritten as well.
Kind regards,
François

Re: how to get the rhow for the MODIS land bands
Hi Zheegang, I understand that you would like to get the water reflectance at MODIS bands that don't saturate. However I don't think you will be able to do it properly. Let me explain. It is indeed possible to adjust the bands provided by Polymer. This is done via the argument bands_rw to the functi...

Re: make auxdata_all crashing
Indeed, the issue is not fully solved yet unfortunately.
I have just uploaded the required files to the forum, so that you can download them until the issue is fully solved: see topic viewtopic.php?f=5&t=93

Auxiliary data
Polymer's auxiliary data should usually be available with the command "make auxdata_all", but in case it does not work, the auxiliary data can be downloaded here and uncompressed in Polymer's folder.

Re: make auxdata_all crashing
Dear zhangYingyin,
Apologies, we are having a hardware issue again, and we are trying to restore it as soon as possible. When it is done, the files will be available again for download.
Kind regards,
François

Re: Problems encountered when processing MDOIS
Dear Ding,
You can use the script tools/make_L1C.py to generate L1C files from L1A. This script uses l2gen. See also section 2.4 of the readme file.

François

Re: SVC gains for Polymer 4.10 and 4.13
Yes indeed, the SVC update follows an update of the algorithm.

Re: Use polymer v4.13 to process OLCI in the presence of thin clouds
Hello, There are many parameters that can be tuned, but most likely none that would improve your results easily. Unfortunately Polymer is known to retrieve underestimated values of water reflectance in moderately to highly turbid waters. We are doing research on this topic and hopefully this will im...

Re: luts.py error
Can you check that luts.py has not been modified ? The line 999 of this file is part of a multi-line statement, and I don't see why there would be an invalid syntax here. Or double-check that you are not using python2 by accident, I think this might be the most likely issue. Just type $ python --ver...
