R Documentation

Run model under steady state conditions

Description

Rapid method for calculating below or above canopy or below ground microclimate under steady-state at one user specified height.

Usage

runmodelS(
  climdata,
  vegp,
  soilp,
  nmrout,
  reqhgt,
  lat,
  long,
  metopen = TRUE,
  windhgt = 2,
  surfwet = 1,
  groundem = 0.95
)

Arguments

`climdata`	data.frame of climate variables needed to run the run the model (dataset should follow format of `weather()`)
`vegp`	a list of vegetation parameters as returned by `microctools::habitatvars()`.
`soilp`	a list of soil parameters as returned by `soilinit()`
`nmrout`	a list of putputs from NicheMapR as returned by `runNMR()`.
`reqhgt`	height (m) for which microclimate is needed.
`lat`	latitude of location (decimal degrees).
`long`	longitude of location (decimal degrees).
`metopen`	optional logical indicating whether the wind measurement used as an input to the model is from a nearby weather station located in open ground (TRUE) or above the canopy for which temperatures are modelled (FALSE - see details)
`windhgt`	height above ground of wind measurement. If `metopen` is FALSE, must be above canopy.
`surfwet`	proportion of leaf surface acting as free water surface
`groundem`	thermal emissivity of ground layer

Details

This is a rapid implementation of model when time increments are hourly such that transient heat fluxes and heat storage in canopy can be ignored. Computations are performed simultaniously on all data, negating need to run in timesteps. Also includes implementation of model with snow present. Should generally be run using wrapper function runwithNMR() but provided as a standalone function in case data for multiple heights are needed, in whihc case it can be run multiple times without also running NicheMapR.
