Climate-sensitive site index models for Norway
Description
Implementation of models for climate-sensitive site index models for Norway as described in Antón-Fernández et al. (2016).
Usage
AM2016ClimateSensitiveSINorway(soilquality, t.early.summer, waterbal, SI.spp)
Arguments
soilquality |
A factor with levels 1 to 5 indicating the soilquality category. 1 being the poorest soils and 5 the best soils |
t.early.summer |
A vector with sum temperatures (in C) in spring and early summer (april, june and july) |
waterbal |
A vector with the montly moisture surplus in June (difference between the 30-year mean precipitation in June and mean potential evapotranspiration in June.). |
SI.spp |
SI species, that is, the species for which SI should be calculated. 1 = spruce, 2 = pine, 3 = birch. |
Value
Returns a vector with the estimated SI.
