Re: Add DEM

Dear Marcela, The SRTM implementation in Polymer (polymer/srtm.py) is not related to github.com/tkrajina/srtm.py. I think the comment # srtm.py was misleading, I was meaning that the SRTM3 class (the class is actually SRTM3, and not SRTM, I will fix the doc) is implemented in srtm.py, and GLOBE in g...

Re: Polymer installation

Dear Npal, In case you are still stuck on this issue, you could maybe try installing an envionment with python3, which is recommended anyway over python2 (and I realize that I should update the installation script to more explicitly create an environement with python3). For that, just use the follow...

Re: Support for netCDF I/O?

Hi Peter, The calculation of optical depth spectral profiles is not executed on GPU, it is part of the preparatory computation (run in atmosphere.py), that are provided to the radiative transfer code. Are you interested only in the optical depth, or in the radiative transfer ? It is possible to use ...

Re: Projection deviation

Dear Joao, I have already been related some geolocation issues with Polymer results using SNAP. This seems to be still be an open issue. But I don't see what might be the issue on Polymer side, the lat/lon fields are simply taken from the Level1. I will ask for advice on the SNAP forum. Cheers, Fran...

Re: How to add new parameters as output

Great news!
The warning is ok, it does not affect the results. I'll try to get rid of it in the future.
Thanks for the feedback,
François

Re: How to add new parameters as output

Dear Joao, Adding parameters to the output can be done as follows : from polymer.level2 import default_datasets run_atm_corr(l1, Level2_NETCDF(..., datasets=default_datasets+['sza', 'F0'])) But two remarks : The aerosol optical thickness is not estimated in Polymer. This is due to the atmospheric mo...

Re: polymer v4.10 installation

Dear Rif, Polymer is not provided as a pip bundle. You have to uncompress the tar.gz archive first. On windows you can use for example 7-zip and then find some help in the README file. However, the primary operating system for Polymer is linux. Issues are likely if you try to run it on windows, rega...
