+== Step 2: Regrid from MERRA ==
+The next step is to use Joe Stassi's regrid.pl script to create some restarts at 21z on 1990-NOV-28. We'll first run two sets of runs at 144x91 and c48 to get a command to use for automated generation.
+=== Run regrid.pl for 144x91 ===
+ $ cd $ESMADIR/Linux/bin
+ $ ./regrid.pl

+When this succeeds you'll have a file, b_d5_merra_jan89.19901128_21z.CMD, which details how the regrid.pl ran:

+== Step 3: Regrid the good Landice restarts ==
+Now we need to work at getting a good LANDICE restart. Again we'll use Joe's script.
