Landsat 8 gain and offset
WebbRadiance gain, radiance bias, and sun irradiance for each band; Reflectance gain and reflectance bias (for Landsat 8) The function performs two corrections. The first is based on the gain settings. The original brightness values are re-created from the image values by reversing the gain equations. Webb21 nov. 2014 · Launched in February 2013, the Landsat-8 carries on-board the Thermal Infrared Sensor (TIRS), a two-band thermal pushbroom imager, to maintain the thermal imaging capability of the Landsat program. The TIRS bands are centered at roughly 10.9 and 12 μm (Bands 10 and 11 respectively). They have 100 m spatial resolution and …

For instance, a target with an at-satellite temperature of 0C will appear to be 0.8C based on the image data and a target with an at-satellite temperature of 27C will appear to be 26.3C. The error at 12C is approximately 0C.
