Sandeep Kumar Patakamuri

GRASS has ACCA module. It may be a faster alternative.

https://grass.osgeo.org/grass73/manuals/i.landsat.acca.html

This is how ACCA works

http://landsat.usgs.gov/l8handbook_section4.php

Section 4.1.4.3.1 Automated Cloud Cover Assessment (ACCA)

I am interested to know why ACCA, why not FMask for cloud detection?

Because it is implemented in Surface Reflectance products of Landsat!

Michael Wulder

ACCA is pretty old school. Agree with Sandeep above, there are more modern tools to apply. ACCA was not developed given the current state of computing offered. A version of Fmask is implemented in downloadable analysis-ready Landsat products. You can query the atmospheric information in the pixel level quality flags. Good luck with your work!
