Re: Negative reflectance for Sentinel B11 and B12 bands in near shores water spectra

Hi Quentin, thanks for your detailed reply. The extension of the wavelenght range has done the right work in shifting back to postive values the SWIR bands. Anyway, I will evaluate now the opportunity of keeping those bands for the DSF calcualtion due to the noise disturbance and surely I will exten...

Negative reflectance for Sentinel B11 and B12 bands in near shores water spectra

Hi Quentin, I am facing a “negative reflectance” problem in the Sentinel-2 images that I correct with ACOLITE. I am finding that water pixels spectra show negative reflectance values in the SWIR bands B11 and B12, but I wonder also if all the spectra band points are shifted down. I am analysing a co...
