Re: Glint correction activation in Polymer

Hi Damianos,
Yes, Polymer does correct for glint and adjacency effects. It does burk correction, so it can not be disactivated.

Re: Problem while running Polymer

Hello,
This may be due to a limitation of hdf4 file format, which does not support files greater than 2Gb.
Please try to use Level2_NETCDF, or Level2(fmt='netcdf4'), instead of Level2().
Cheers,
François

Re: Problem running Polymer on Linux machine

Hi,
Please make sure that your current directory is the polymer root folder ~/AtmCorr/Polymer/polymer-v4.14/
In jupyter notebook, you can use the commands "pwd" and "cd ~/AtmCorr/Polymer/polymer-v4.14/".
Then you should be able to run the import commands.
Cheers,
François

Re: batch processing erorr

Dear Jonathan, There should be no pileup of tmp files. As you have noticed, there is a tmp file created for each processing, but it is moved to the final file at the end of the processing, avoiding unfinished files in case processing stops for whatever reason. The other issue (https://forum.hygeos.c...

Re: Missing Rw in polymer output for MODIS

Dear Jonathan, Apologies for the late answer. The L1C file should be fine. But you can indeed specify which bands you are interested in, with the following argument: run_atm_corr(..., bands_rw=[412,443,469,488,531,547,555,645,667,678,748,859,869,1240]) (or just a subset of these bands) Please note t...

Re: Sub-image processing

Hello, You can indeed process a sub-image, but using a range of rows/columns (not latitudes/longitudes). This can be achieved by passing the arguments sline, eline, scol, ecol, to the Level1 object: Level1_MSI(..., sline=1000, eline=2000, scol=1000, ecol=2000) (and same for all other Level1 objects)...

Re: OLCI inland waters

Hello,

Please note that the latest version of Polymer allows processing inland waters by default for OLCI, and thus does not require an alternative land mask.
Cheers,
