efflux: Extract efflux rates

In ConFluxPro: Soil Gas Analysis and Flux Modeling

Extract efflux rates

Description

Calculate or extract the soil/atmosphere efflux from cfp_pfres or cfp_fgres model results.

Usage

efflux(x, ...)

## S3 method for class 'cfp_pfres'
efflux(x, ...)

## S3 method for class 'cfp_fgres'
efflux(x, ..., method = "lm", layers = NULL)

## S3 method for class 'cfp_altres'
efflux(x, ...)

Arguments

x	A cfp_pfres or cfp_fgres model result, or a cfp_altres.
...	Arguments passed to methods.
method	Method(s) used to interpolate the efflux at the top of the soil from partial fluxes within the soil. One of top Use the flux in the topmost model layer. lm A linear model where each partial flux is centered in the respective layer and the model is evaluated at the top of the soil. lex Linearly extrapolate using fluxes of two layers in the soil.
layers	Vector of two integers selecting the layers for the lex method. Layers are indexed from 1 (topmost) to the number of layers used in the flux calculation.

Value

A data.frame with one row for each combination of id_cols and the column efflux in µmol m^{-2}s^{-1}.

Examples

my_dat <- ConFluxPro::base_dat |>
  filter(Date < "2021-03-01") #subset to speed up example
PROFLUX <- pro_flux(my_dat)
FLUX <- fg_flux(my_dat)

efflux(PROFLUX)
efflux(FLUX)
