Landsat 8 cloud segmentation approach

Hi folks,

I read about your Landsat 8 cloud segmentation approach here:

… and here:

I like the simplicity of your approach and implemented it in the google earth engine:

… but ran in to obvious problems:

(1) the floor command must be a mistake as it reduces the term to zero (term3_1)

(2) the output does not result in a cloud mask (term 1 results in high numbers > 1.5 , which is making the comparison with the SWIR2 band pointless)

I double-checked the formula (as provided in the resources). It is implemented correctly as it is stated.

I am wondering if there is anything I overlooked.

Any help to resolve this issue would be very much appreciated.

best regards,
