add_evap_isotopes: Add evaporation isotopes to dataset

In WDNR-Water-Use/CSLSchem: CSLS Water Chemistry Analysis

Description

Adds evaporation stable isotope measurements, calculated with "calculate_Cevap" in Cevap_functions.R.

Usage

add_evap_isotopes(
  tracer,
  weather,
  chem_df,
  start_date,
  end_date,
  chem_tracer,
  seasonal_correction
)

Arguments

tracer	data frame with water chemistry information for stable isotope.
weather	data frame with monthly weather
chem_df	data frame with water chemistry information for this analysis, for getting lake surface temperature.
start_date	start date of analysis.
end_date	end date of analysis.
chem_tracer	name of stable isotope, "d18O" or "d2H".
seasonal_correction	logical defaults to TRUE to incorporate seasonal correction factors for d18O_atm based on difference between calculated and reported d18O_atm values in Krabbenhoft et al. (1990).

Value

Cevap, new data frame with same columns as tracer, but with only calculated evaporation values.
