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...

Re: Polymer for Sentinel-2

Hello, Yes there are three options that you can use to make it faster : from polymer.gsw import GSW run_atm_corr( Level1_MSI(name, resolution='10', sline=1000, eline=2000, scol=1000, ecol=2000, # (1) process only a part of the image (coordinates within the 10980x10980 image because we are at 10m res...

Re: Sentinel 3 - missing bands 681 & 709

Dear Lazaros,
You can update Polymer to v4.10, these bands have been added by default in v4.9 (see changelog)
With v4.8 these bands can be written by passing argument bands_rw = [400,412,443,490,510,560,620,665,681,709,754,779,865,1020] to the function run_atm_corr.
Cheers,
François
