…lculations. This calculates the initial accumulation/interception of snow in the canopy following: Cebulski, A. C., & Pomeroy, J. W. (2025). Snow Interception Relationships With Meteorology and Canopy Density. Hydrological Processes, 39(4), e70135. https://doi.org/10.1002/hyp.70135 Interception efficiency is calculated as a function of atmospheric snowfall and canopy density. Canopy density is defined using the snow-leaf contact area which is approximated as function of nadir canopy coverage and the hydrometeor trajectory angle. Applicable for a range of forest densities that do not have large clearings/clear cuts.
…es.h` so they can be shared with the new `CanopySnowBalance` module. Snobal functionality remains the same. A comment was also added in ref to issue https://github.com/issues/created?issue=srlabUsask%7Ccrhmcode%7C465

This module is designed to be paired with the `CanopyVectorBased` module and together replace the typically used `CanopyClearingGap` module.

Implemented new canopy snow energy and mass budgets as new CRHM modules. The main changes are the addition of two new modules to represent the initial loading of snow in the canopy:
CanopyVectorBasedwhich follows developments from:Cebulski, A. C., & Pomeroy, J. W. (2025). Snow Interception Relationships With Meteorology and
Canopy Density. Hydrological Processes, 39(4), e70135. https://doi.org/10.1002/hyp.70135
the second module
CanopySnowBalancefollows developments from:Cebulski, A. C., & Pomeroy, J. W. (under review). Processes Governing the Ablation of Intercepted
Snow. Water Resources Research.
Together these new modules replace the canopy snow routines previously incorporated in CanopyClearingGap. The original radiation routines in CanopyClearingGap were copied over to the CanopyVectorBased module which feeds into the surface snowpack routines so CanopyClearingGap is no longer needed.
See individual commits for additional details.
