Yang Liu,
On a non-netCDF topic, I tried grabbing the corresponding GeoTIFF

The first concern, is that you have two tiepoints and a
pixel scale (size). Normally if you are using pixel scale
you would only use one tiepoint. I'm not sure if the form you have provided is allowed by the specification or not, but it is likely to confuse many packages (as it does GDAL) which treats it as have two tiepoints and ignores the pixel scale.Also, you don't seem to have defined the projection at all. I'm not sure what ProjectionGeoKey = 47 is supposed to be, but I don't think it is valid.
