snowtemphumE: Above ground snow microclimate model

In ilyamaclean/microsnow: Below or above canopy microclimate modelling with R in snowy environments

Above ground snow microclimate model

Description

Used by e.g. runmicro_hr() to model microclimate above ground

Usage

snowtemphumE(
  microsnow,
  reqhgt = 0.05,
  pai_a = NA,
  xyf = 1,
  zf = NA,
  slr = NA,
  apr = NA,
  hor = NA,
  wsa = NA,
  gmn = 0.3
)

Arguments

microsnow	an object of class microsnowin as returned by snowmodelin()
reqhgt	specified height (m) above or below ground for which microclimate outputs are required. Negative below ground
pai_a	total plant area index above reqhgt. Estimated if not supplied (see details).
xyf	optional input for called function snowwind()
zf	optional input for called function wind()
slr	an optional SpatRaster object of slope values (Radians). Calculated from dtm if not supplied.
apr	an optional SpatRaster object of aspect values (Radians). Calculated from dtm if not supplied.
hor	an optional array of the tangent of the angle to the horizon in 24 directions. Calculated from dtm if not supplied.
wsa	an optional array of wind shelter coefficients in 8 directions. Calculated from dtm if not supplied.
gmn	optional minimum convective conductance value (mol/m^2/s). See snowwind())
