Re: error in processing sentinel 2
Hello,
I see the numpy.float alias has been dropped since numpy 1.24. So, two solutions:
- Downgrade to numpy 1.23
- Or rename np.float to float in polymer/luts.py: line 187. This will have no incidence on the code. I will include this modification in next release v4.15
Cheers, François

Re: error in processing sentinel 2
Hello,
What is your version of numpy ?
python -c 'import numpy ; print(numpy.__version__)'
Cheers, François

Re: Auxdata_all for 4.13 on Mac
Sorry to come late on this issue, but I am not familiar with macos environments. I didn't understand if your issue is that you couldn't install wget, or did it still fail after doing so ?

Re: Sentinel 2 striping
The striping in Sentinel-2 is due to the multiple detectors with a staggered configuration : the detection angles alternate across detectors (https://sentinels.copernicus.eu/web/sentinel/technical-guides/sentinel-2-msi/msi-instrument). Of course this is particularly visible in the sun glint. Polymer...

Re: Support to Landsat 5 and 7
Dear Rafael, There is no plan to support these sensors, because they have a limited number number of spectral bands, and the applicability of Polymer in these conditions would require not only the implementation of a dedicated reader, but also an evaluation of how Polymer behaves in these restricted...

Re: What does bbs represent?
Hello, Indeed, this parameter is not named properly. The variable name "bbs" was used because in earlier versions of Polymer, another water reflectance model was used (Morel and Maritorena, 2001). This model is still implemented in Polymer, but the default is now PR05. Your analysis is perfectly cor...

Re: Feature: include OLCI b09 in output
Dear Tiago,
You can include the output at band 673, by passing the following argument :
run_atm_corr(..., bands_rw=[400,412,443,490,510,560,620,665,674,681,709,754,779,865,1020])
By default, this band is indeed not included (see params.py:323)
Cheers,
François

Re: Polymer flags
Dear Minsun Lee, Thanks for your message ! Yes it seems you are using the flags correctly. To answer your questions : - 256 is not used, it is a placeholder - no problem about that. - 1 is missing because there is no land mask in Sentinel 2 level1 products. To apply a land mask, you can use GSW by p...
