I have a raster that represents temperature on a global scale derived from satellite data. Initially it had pixels in the ocean assigned -9999. After I used SetNull tool to eliminate them they show up now as No Data values when I use Identify tool in ArcMap. However, when I use Pixel Inspector tool they are assigned -3.4028234663852886e+38. What could be the reason for that? I am doing some analysis after converting this raster to an array and I think these values mess up my output because I am getting unreasonably large range of values for temperature.
