Landsat 8 Thermal Update

Landsat 8 Thermal Infrared Sensor (TIRS) data continue to be collected with the scene select mirror encoder electronics disabled (mode 0). While in this mode, the TIRS line of sight model (LOS) will be regularly updated and modifications are being made to automate revisions to the LOS in the Level-1 Product Generation System (LPGS). Landsat 8 Operational Land Imagery (OLI) and TIRS data that have been collected through the 4th quarter of 2015 (October-December) will be reprocessed into nominal Level-1 products containing valid TIRS data, and will be available in February 2016. TIRS data acquired during the 1st quarter of 2016 (January-March) will be reprocessed and made available in April. A strategy is being developed for generating near-real time products moving forward while operating in mode 0. More details will be posted on the Landsat Missions Web site as they become available.
