Apply fDOM temperature and turbidity corrections

Source: R/fdom-correction.R
correct_fdom.Rd

Takes functions and coefficient values and applies them to fDOM data within a sonde project to apply fDOM corrections. Uses flags stored within the project to only correct data that hasn't previously been corrected. Additionally, turbidity corrections will only be applied to temperature corrected data.

Usage

correct_fdom(proj, temp = NULL, turb = NULL)

Arguments

proj

A sondeproj object.

temp

Either NULL or a list object (see details) for temperature correction.

turb

Either NULL or a list object (see details) for turbidity correction.

Value

A data.frame object with fDOM updated with the corrections.

Details

To apply a correction you must supply a list object with the following structure:

  • params: a named list with parameter values where the names match the arguments within the function

  • fun: a function to apply to the fDOM data where the first argument is fDOM, the second is either temperature or turbidity, and the third is parameters within the function, pulled from params.

Examples

temp <- list(params = list(rho = -0.011),
             fun = function(fdom, temp, parms){fdom / (1 + parms$rho*(temp - 25))})
corr_data <- correct_fdom(example_sondeproj, temp=temp, turb=NULL)
