I’ve found that the BRR reflectances I obtain from SNAP might have still a strong Rayleigh signal. I get this idea (which might not be accurate) by comparing with a home made processor I’ve been working on.
As a first “evidence”, let me show you the blueish foreground I get in the RGB composite from SNAP RC reflectances:
As a second “evidence”, observe that in all pins (last figure) I get a strong blue signal difference which seems to match quite well a Rayleigh reflectance functional type (sort of lambda^-4). Might there be an issue here? Or it’s me that haven’t interpreted thr rBRR magnitude as I should have done?
Any reply will be useful. Thanks a lot!!
