canopy_resistance m s-1 [UVAA] Canopy resistance is the overall resistance to water vapor transfer from a vegetated canopy to the atmosphere. It incorporates the effects of stomatal resistance (vapor transfer from inside the leaf to its surface), leaf boundary layer resistance (vapor transfer from the leaf surface to the surrounding canopy air), and canopy structure (e.g. multiple canopy layers).

canopy_resistance_to_water_vapor_transfer m s-1 [UVAA] Canopy resistance is a function of the canopy stomatal resistance (Rstom), the canopy cuticle resistance (Rcuticle), and the soil resistance (Rsoil). "Canopy" means the vegetative covering over a surface. The canopy is often considered to be the outer surfaces of the vegetation. Plant height and the distribution, orientation and shape of plant leaves within a canopy influence the atmospheric environment and many plant processes within the canopy.

canopy_resistance_to_evapotranspiration m s-1 [UVAA] Canopy resistance to evapotranspiration is the overall resistance to water vapor transfer from a vegetated canopy to the atmosphere. It incorporates the effects of stomatal resistance (vapor transfer from inside the leaf to its surface), leaf boundary layer resistance (vapor transfer from the leaf surface to the surrounding canopy air), and canopy structure (e.g. multiple canopy layers). "Evapotranspiration" means all water vapor fluxes into the atmosphere from the surface: liquid evaporation, sublimation and transpiration. The canopy is often considered to be the outer surfaces of the vegetation. Plant height and the distribution, orientation and shape of plant leaves within a canopy influence the atmospheric environment and many plant processes within the canopy.
