fetch3.scaling#

Provides scaling functions to convert common parameters to model parameters, and convenience functions for unit conversions of transpiration.

Config parameters that will be provided by the user:

\(\mathrm{LAI_p^{(sp)} \ [m^2_{leaf (sp)} / m^2_{ground}]}\): species-specific plot-level LAI
\(\mathrm{SD [trees \ hectare^{-1}]}\): stand density [# trees per hectare]
DBH (stem diameter at breast height [cm])
Sapwood depth [cm]
\(\mathrm{A_c^{(sp)} [m^2]}\): Mean crown area (species-specific)

Calculated parameters:

species-specific crown-level LAI (LAIc_sp) [m2 leaf (sp) / m2 ground]
sapwood area [m2]
xylem area index (Aind_x) : [m2 xylem m-2 ground]

Functions

`calc_Aind_x`	Calculates the crown-level xylem area index [m2 xylem m-2 crown projection]
`calc_LAIc_sp`	Calculates the crown-level species-specific LAI (LAIc_sp [m2 leaf (sp) / m2 ground projection of crown]), using the plot-level species-specific LAI (LAIp_sp [m2 leaf (sp) / m2 ground in plot]), mean crown area of the species [m2], and the stand density of the species in the plot [# of trees of sp / hectare].
`calc_xylem_cross_sectional_area`	Calculate xylem cross-sectional area from DBH and active xylem depth
`convert_sapflux_cm3hr_to_m3s`
`convert_sapflux_cm3hr_to_mm30min`	Converts aggregated plot-scale sapfluxnet data (in units of m3h20 m-2ground hr-1 to mm 30min-1
`convert_sapflux_m3s_to_mm30min`
`convert_trans2d_to_cm3hr`
`convert_trans_m3s_to_cm3hr`
`integrate_trans2d`
`trans2d_to_tree`
