[gradsusr] Unable to read a netCDF file because the variable file name is apparently too long

I have a netCDF file with satellite brightness temperatures in it, and 
the variable name is 'Brightness_Temperature', which is acceptable 
according to the CF Standard Name Table 
However, when I try to read it in GrADS, the variable name appears to be 
truncated to 17 characters and thus GrADS can't read it:

> Syntax Error:  Invalid Operand
>   'brightness_temper' not a variable or function name
>   Error ocurred at column 1
> DISPLAY error:  Invalid expression
>   Expression = brightness_temperature

Is there a relatively straightforward way around this?  Thanks!
