Data and Deglinting

TOA TCC: raw image logarithmic enhancement	BOA TCC deglinted image logarithmic enhancement
Glint regressions using SWIR1 No pan-sharpening applied R2 values are fairly high 15 m resampling does not increase noise

Optical calibration
for the whole image
16U data are scaled to allow for comfortable screen display

Calibration diagram for the whole image for bands Blue, Green, Red and NIR	Calibration diagram for the whole image for bands Blue, PAN, Red, NIR CoefKPan=1.05
0-5m: K_BLUE/K_GREEN=0.855 Jerlov water type OII+0.9 5-13m: clearing progressively to OII+0.3 13-25m: clearing progressively to OIB+0.8	Calibration diagrams are just as good for a 15m GSD pansharpened image as it is for original 30 m GSD data "stratified waters" actually a fairly complex Failing to account for it entails poor control of the optical calibration and artifacts in the results
	"Stratified waters" Profile Blue location backdrop is a BOA TCC WCC The RED and NIR bands exhibit higher deep water radiance where Coastal water type rules: this is suspended particles load

Ready for modeling

BOA CC WCC normalized
BGR color composite:

Blue=Coastal band
Green=Green band
Red=Blue band

GSD 15 m Pan-sharpened using Rstudio
gives the same results
does not require smoothing
