Try Nasa's Panoply - netCDF, HDF and GRIB data viewer. https://www.giss.nasa.gov/tools/panoply/download/

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)

Thanks Dan;

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.
