Landsat Level-1 Products Registration Success by Cloud Cover

This image displays each cloud-cover class and lists the proportion of Landsat data that process to an L1TP, those that fallback to an L1GT or L1GS after a failed attempt to produce an L1TP (clouds or poor ephemeris data), and the proportion that are planned to produce an L1GT (night, Antarctica or insufficient land features).
