 You may want to modify the default soil, landuse or other land surface data on the surface file if you have measurements or a different data source of higher resolution or similar available. 
 You can do this by accessing the relevant variables on the surface file. 
 
-These may include:
+Variables you want to modify may include:
 
 Soil:
-- PCT_SAND: percentage sand at soil levels (10 levels are considered)
-- PCT_CLAY: percentage clay at soil levels (10 levels are considered)
-- ORGANIC: organic matter density at soil levels (10 levels are considered)
