April 16, 2015 - Landsat 8 Thermal Data Reprocessing Update

On March 6, 2015 we reported that the Landsat 8 Thermal Infrared Sensor (TIRS) resumed normal imaging operations, and outlined plans for reprocessing data acquired since December 19, 2014, when problems occurred in the A-side electronics of the sensor. Provisional TIRS data acquired since March 13, 2015 were expected to require reprocessing to refine the absolute calibration; however, based on a small number of vicarious measurements, it has been determined that these data will not need to be reprocessed for now since the radiometry appears to be consistent with the previous A-side data. The calibration will be monitored and updated in the future if needed.

Beginning April 30, 2015, Landsat 8 scenes acquired from December 19, 2014 to March 13, 2015 will be reprocessed to include valid TIRS data. The reprocessing effort is expected to complete by May 18, 2015. TIRS data for a number of scenes will not be processed due to non-nominal instrument configuration. (Read More).
