Detailed Description

Canopy data used as a pointer in the SnowStation structure

INSTANTANEOUS VARIABLES
1. Canopy "state" variables, and some auxiliaries
2. Properties which could be given here or as a parameter field
3. Aerodynamic resistances
CUMULATED/AVERAGE VARIABLES
cumulated between time series output timesteps - these variables can be moved or mirrored in a canopy "surface" data structure
1. Albedo and similar auxiliaries
2. Radiation fluxes
3. Canopy turbulent heat fluxes
4. Canopy evaporative fluxes
5. Canopy mass fluxes.
