Hi @BrianWilson1 can you please merge this with your version of master then make an attempt to run the code.
Right now I get the following issue

lmcgibbn@LMC-056430 /usr/local/climate/ocw-parallel(master) $ python functions.py 1 "http://zipper.jpl.nasa.gov/dist/AFRICA_KNMI-RACMO2.2b_CTL_ERAINT_MM_50km_1989-2008_tasmax.nc" "tasmax" "wrf_bias_compared_to_knmi" "http://zipper.jpl.nasa.gov/dist/AFRICA_UC-WRF311_CTL_ERAINT_MM_50km-rg_1989-2008_tasmax.nc" "tasmax"
