If you can see from the figure the values are in some decimal places while as it should me in the range of real numbers

Visually that could be a normalization or some other symbology issue.  Are the values in the raster actually wrong?  (check the histogram etc)

Actually the values should be Brightness Temperature values but these are some thing else and also the resolution is also changed. I have attached a sample file if you can check it.
