Beginning February 3, 2014, all Landsat 8 data held in the USGS archives will be reprocessed. All Landsat 8 scenes will be removed from the online cache at this time and the data will then be reprocessed starting with the most recent acquisitions and proceeding back to the beginning of the mission. Data will then become available for download. Scenes waiting to be reprocessed will also be available for on-demand product orders. Reprocessing is expected to take approximately 50 days.
