Hello,
There seems to be a problem in your NetCDF library. Could you provide more information about your system and python environment ?

Well, it seems that the process has been killed by the kernel for some reason.
Since it was killed, the temporary files are not cleaned up. You can try to use the command 'dmesg' to see the kernel log and get more insight.

Dear Ming, Your problem seems to be related to some non-ascii file path in your installation. But I don't know which one, since you mention "root@ming:/home/ming/Desktop/polymer-v4.12" Non-ascii file paths are a typical issue with python 2. I recommend you use python 3, which can easily be installed...

Dear Joao, Indeed, the same SVC gains are applied to both OLCI instruments because specific gains for OLCI-B have not yet been generated. However in v4.11, the gains were set to 1, as you can see on line 332 (self.calib=None). The variable `calib_OLCI_VC` on line 55 is not used actually. In v4.12, t...

Dear Kim,

Polymer provides normalized water reflectance (sometimes called water leaving reflectance). Remote-sensing reflectance in sr^-1 can be obtained by dividing by pi. More information here.

Kind regards,

Hello,

Indeed, there has been a change on the access to ancillary data on NASA servers. Please see this thread :
viewtopic.php?f=7&t=50

I recommend to use Ancillary_ERA5 or modify ancillary.py as described in this thread, until I release a fix.
Cheers,
François

Great, thanks for sending your solution !
It's not so bad as you say, but it will need a fix for the long term.

Hi Blake, and thanks for your feedback. Indeed, you have done nothing wrong. The problem is that downloading on oceancolor.gsfc.nasa.gov now (since January) requires an EarthData login. There will need to be a modification in polymer/ancillary.py to reflect this change. In the meantime, I suggest yo...

The problem here is that S3A_OL_2_LFR... is a level2 product.
You need to apply Polymer to a level1 product, thus starting with S3A_OL_1_ or S3B_OL_1_.
Otherwise it should work as you did.
Kind regards,
François

Hello,
The best documentation for that is currently in the docstrings, which are the strings coming at the top of each function/class in Polymer's source code.
A proper documentation is in preparation, though.
Kind regards,
François
