The northern reaches of North America are getting greener, according to a NASA study that provides the most detailed look yet at plant life across Alaska and Canada. In a changing climate, almost a third of the land cover – much of it Arctic tundra – is looking more like landscapes found in warmer ecosystems.

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).
