I checked your dataset and here is my finding:

there are three variables: temperature, precip, and qpesum. You should be able 
to get what you wanted for temperature and precip, 
these two variables are in good shaped. There should be no difference between 
AR and no AR regarding the range of rendering.

But QPESum is different since there is zero attribute associated with this 
variable, no data range, missing value, and other attributes. I
don't see why AR will play any role in this variable. The attached image is 
without AR and I set the color table range to 0 and 1.
