I was looking at the L2A_CAL_AC_GIPP.xml file and I think that there might be a mistake in the resolution tag. I am using Sen2Cor 2.4.0 on a Linux machine and the file, which is located in ~/Sen2Cor-2.4.0-Linux64/lib/python2.7/site-packages/sen2cor/cfg, has the following resolutions:
<Resolution> <Band_List> <!-- full width half maximum --> <fwhm>0.018800</fwhm> <fwhm>0.064400</fwhm> <fwhm>0.034800</fwhm> <fwhm>0.028800</fwhm> <fwhm>0.014400</fwhm> <fwhm>0.014800</fwhm> <fwhm>0.018800</fwhm> <fwhm>0.014400</fwhm> <!-- B8 --> <fwhm>0.022800</fwhm> <!-- B8A --> <fwhm>0.019200</fwhm> <fwhm>0.028800</fwhm> <fwhm>0.088400</fwhm> <fwhm>0.172800</fwhm> </Band_List> </Resolution>
The problem is with B8 which has FWHM of 14.4 nm instead of 115 nm which I expected. Is this a mistake?
I was looking at the configuration file because I wanted to see if it is possible to set an option to produce B8 (in addition to B8A) when running Sen2Cor at 20 m resolution. I read the other answers on the forum regarding missing B8 (e.g. SEN2COR-processed L2A data - 2 bands missed) but I think that having B8 could still be useful for some applications (e.g. estimating broadband albedo). Is there a plan to add this option in a future versions of Sen2Cor?
