    mkmapdata.sh with userdefined SCRIP file

    I created a userdefined SCRIP file for a dummy testcase using./mknoocnmap.pl -p 10,10 -n middle -dx 10 -dy 10 -nx 100 -ny 100This created a file with the center at 10,10 latitude, longitude and spanning 5 degrees in each direction, correct? Also I assume the resolution is 10 degrees / 100 = 0.1...

    Dear CESM developers: Is there a guideline for how to compile runoff_to_ocn under cesm1_1_1/mapping/gen_mapping_files? The default set up is done for bluefire. I was wondering if I could use some helps. Any comments would be very much appreciated.
