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...

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...

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...

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

Hi Mohamed,
Case 1 matchups over MOBY and BOUSSOLE have been used for OLCI Polymer SVC (and all Polymer SVC, actually).
Kind regards,
François

Hi Joao, In Polymer, chl-a is not derived from the water reflectance as with bio-optical algorithms like OC4Me : it is derived as part of the optimization scheme. It is the final value of the parameter [chl] to the water reflectance model, described in https://doi.org/10.1364/OE.19.009783 (although ...

Hello, and many thanks for your interest in our tool ! Unfortunately it is currently not possible to get the light field at intermediate depths. We plan that for a next release. One possible implementation would be, as you have seen, to use the Sensor object in backward mode and to place it at the d...

By downloading Polymer you agree to the licence terms and conditions.

This version updates the spectral definition of NASA sensors (MODIS, SeaWiFS, VIIRS), leading to small differences in the results for these sensors.

See more details in the changelog.

Hi Peter, and thank you for your interest in SMART-G. If your NetCDF atmospheric profiles have the same content as the AFGL files, it should be quite straightforward. However if you want your custom atmospheric profile to define also the aerosols, it may be more complex. Could you send an example of...

Answer: Not for the moment
The separation of water leaving radiance from the upwelling radiance above the surface `I_up (0+)` is not possible for the moment. It may appear in a future release.
