twostream: Applies two-stream radiation model

In ilyamaclean/microclimf: Fast above, below or within canopy gridded microclimate modelling with R

Applies two-stream radiation model

Description

The function 'twostream' applies a varient of the Sellers two-stream radiation model to calaculate long and showtwave radiation absorbed by the ground and canopy and shortwave radiation absorbed by leafs.

Usage

twostream(micro, reqhgt = 0.05, pai_a = NA, tfact = 1.5)

Arguments

micro	an object of class 'micro' as returned by [modelin()]
reqhgt	height at which temperatures are required (m). Negative if below ground
pai_a	a SpatRaster of plant area index values above 'reqhgt'. Determined from total 'pai' if not supplied. Must patch the dimensions of 'vegp$pai' if supplied.
tfact	coefficient determining sensitivity of soil moisture to variation

Value

an object of class micro with additional terms added for subsequent modelling
