tom-locatelli/fgr: R Version of the ForestGALES wind risk model

The R version of the wind risk model ForestGALES. It contains both the traditional roughness method (for stand-level calculations), and the 'turning moment coefficient' version (for single-tree calculations). Wrapper functions exist for both methods to calculate the critical wind speeds of damage for stem breakage and tree uprooting. Probabilities of damage can be calculated when information on the local wind climate is known. The package includes model parametrisation for 23 tree species (19 conifers and 4 broadleaves). Users can override most parameters for available species, or introduce new species by providing new parameters values. Functions are available to users to calculate aerodynamic properties of canopies for wind climate modelling, such as canopy roughness and zero plane displacement. Detailed descriptions of both the roughness and the single-tree methods can be found in: Hale, S.E., Gardiner, B., Peace, A., Nicoll, B., Taylor, P. and Pizzirani, S., 2015.
