I am having troubles with extracting data in ArcGIS buffer extractions from the MOD11A2files after processing them into GEOtiff, most of them seem fine but when looking at nightly temperature on some of my coordinates of interest my values go way below zero. Some down to -273. I have multiplied the data with 0,02 and then subtracted 273 to get them as Celsius. Is this a common problem? I can't manage to find anything about it in forums etc and unfortunately I have a tight schedule and am stressed to get the results out.
Anyone familiar with this problem?
