+This testdef is used to test a stealth feature in mpaso introduced by
+PR #2726. It changes one mpaso namelist variable,
+    config_land_ice_flux_mode
+from its default value to 'coupled'.
+This tests the ocn/glcshelf coupling.
+
+It also specified that DATM forcing should be restricted to 1958.
+This allows JRA1p5 forcing to be used without a large input data requirement.
