Surface of Canopy Resistance

The canopy resistance is usually the most difficult of the three flux resistances to evaluate theoretically. Studies of these pathways constitute a major area of dry deposition

Acting in parallel with the foliage resistance is the ground, (or water, r, .), resistance. The ground resistance can be parameterized in the same manner as the cuticle surface resistance, by reference to SO2, A. The surface resistance over wa-
