September 28, 2015 – Update to Provisional Landsat 8 Surface Reflectance (L8SR), Landsat 4-7 Surface Reflectance (LEDAPS) and CFmask shadow prediction

By Landsat Missions

Provisional Landsat 8 Surface Reflectance (L8SR) version 0.3.1 was implemented on September 28, 2015, and included changes to how the climate modeling grid (CMG) is accessed at scene edges, as well as at land/water boundaries. 

Landsat 4-7 Surface Reflectance (LEDAPS) version 2.3.1 was implemented on September 28, 2015, which includes bug fixes to saturation flagging. Saturation was previously incorrectly flagged as 16000, but is now flagged correctly at 20000. 

For both LEDAPS and L8SR, the CFmask was modified to correctly select cloud heights for shadow projection. Previously, the ideal cloud height was not being selected.
