-# By default, for each listed OCN resolution, mapped ocean masks will
-# be generated for C12,C24,C48,C96,C192,C384,C768 and C1152. For C3072
-# resources and memory will need to be increased. See rt.sh notes.
-# If a list of ATM resolutions is included below, limit ATM resolutions
-# to those listed (eg. mx100 | 12,24,96)
+# Baseline configurations are defined as
+# TEST_NAME | ATMRESLIST
+# TEST_NAME is one of the available ocean resolutions from
+# 9deg (mx900) through 1/4deg (mx025)
+# If ATMRESLIST is empty, mapped ocean mask files for ATM
+# resolutions from C12 through C3072 will be generated for each
+# ocean resolution
+# Note that C3072 requires additional time and resources, see
+# rt.sh
+# The ATMRESLIST can also be specified as a subset of all available
+# ATM resolutions, eg: C12,C24,C48 or C96,C1152
