Unsigned/Signed bytes in NCL

Hello,

I am a new user to NCL. I am using NCL version 6.1.2.
I have been having some trouble with NCL in reading byte data from netCDF files. I have a variable that I am trying to read that has all positive values (reflectivity), but the missing_value is -99. NCL seems to only want to read it as a unsigned byte (0 to 255) which means the variable shows a non-uniform error message.

Is there any way to get NCL to read the data as a signed byte type so that the -99 values are valid in the data set?

Thanks for your help,
Lisa
