4SM Landsat 8 at Marawaah Island, UAE

The data:
Nine Landsat 8 OLI images

Complex and variable atmosphere clouds, adjacency effect, path radiance increasing from spring to summer, streaks of industrial smoke, and sea-surface glitter all need to be thoroughly removed through the "deglinting" process, based on the observed minimum radiance in the SWIR1 band over optically deep waters it is obvious here that sampling the image for glint regressions requires the whole image	SWIR1 band at 1610 nm has extremely low water penetration is very well correlated with other bands therefore is an excellent base for deglinting
April 20th TCC	April 20th SWIR1 glint regression TCC deglinted
May 22nd TCC	May 22nd SWIR1 May 22nd SWIR2 glint regression looks excellent but deglinting is awfully bad
June 7th TCC glint regression is excellent, even the PAN vs SWIR1, which usually tend to be fuzzy see SWIR1 : this is a very homogeneous atmosphere==>it deglints very well Calibration diagram for the PAN band: X2 vs X4	June 7th TCC deglinted Deglinting is very good, apart from the electronic noise. The problem at the far east can be corrected for. Profile White is shown. see deglinting of the PAN band along Profile White Can you apply a formal atmospheric correction to this scene: I'd be interested to compare with my simple "dark pixel" solution. and this potentially shall allow me to validate my estimation of the all-important water volume reflectance: Lw=Lsw-La
June 23rd TCC see the SWIR1	June 23rd deglinted glint regression is excellent
July 9th TCC see SWIR1 glint regression is excellent Calibration diagram for PAN band_4 see that RM, Rw and Ra are displayed	July 9th TCC deglinted looks good BUT WAIT: force the enhancement Deglinting can be very frustrating! Results can only be questionable
July 25th TCC Stuffy atmosphere in july, no cloud at all the glint regressions are good	July 25th TCC deglinted looks good BUT WAIT: force the enhancement Deglinting can be very frustrating! Results can only be questionable
August 10th TCC can't get suitable glint regressions no results	There are several atmosphere types here, each with its own disting set of glint regressions: I give up.
August 26th TCC glint regressions were quite difficuly to obtain	August 26th TCC deglinted Deglintinng is found wanting!!!!
September 11th TCC glint regressions are splendid but quite difficult to obtain atmosphere is very heterogeneous	September 11th TCC deglinted "so to speak"!!!
