dcdz_layered
Description
This function calculates concentration gradients using different approaches.
Usage
dcdz_layered(df, layers_map, mode)
Arguments
df |
(dataframe) the gasdata dataframe, filtered to one profile (e.g. 1 day & one Plot ). |
layers_map |
(dataframe) containing the following parameters:
|
mode |
(character) One of ("LL","LS","EF","DA"). |
Value
df (dataframe) same structure as layer_map with following columns:
- mode (character)
The used gradient method.
- layer (character)
the layer name
- upper (numeric)
upper boundary in cm
- lower (numerirc)
lower boundary in cm
- dcdz_ppm (numeric)
concentration gradient in ppm/cm.
- dcdz_sd (numeric)
standard error in ppm/cm.
- dc_ppm (numeric)
concentration difference in ppm.
- r2
(linearised) R^2 for the model.
Examples
{
df <- data.frame(depth = c(10,0,-100),
x_ppm = c(400,800,5000),
gd_id = c(1,1,1))
lmap <- data.frame(upper = c(10,0),
lower = c(0,-100),
layer = c("HU","MIN"))
dcdz_layered(df,
lmap,
mode = "LL"
)
}
