I'm trying to find Land Surface Temperature of 4 continuous Landsat8 images in ArcGIS. I was able to calculate them as individual panels (using these two videos as guidelines: https://www.youtube.com/watch?v=uDQo2a5e7dM ; https://www.youtube.com/watch?v=GwwXhMKo-yM), but that created nodata values that I couldn't eliminate.

My alternate approach was to create a mosaic of the images using composites of each image, but this leaves out bands 10 and 11, which I need to do the LSE calculations. The concern I have with this is that all four images have different thermal band values/properties; if these bands don't make it into the mosaic in the way the images will, how can the calculation be done?

How can I do this in ArcGIS Desktop?
