The values in the the downloaded raw Landsat 8 images are so called Digital Numbers of the sensor. One of the bands of a Landsat 8 scene is named "BQA" which contains for each pixel a decimal value representing a bit-packed combination of surface, atmosphere, and sensor conditions found during the overpass. So I was very surprised when it came out the other way around. I suspect if Landsat went over after midday or in the afternoon, urban areas would come out much hotter than these grasslands but unfortunately Landsat data doesn’t allow us to test this assumption. In turn, the LST influences the partition of energy between ground and vegetation, and determines the surface air temperature. This is done with the following equation and also needs some data from the metafile: http://landsat.usgs.gov/Landsat8_Using_Product.php.
