eee2eye: Calculate the E:I for a Steady-State Lake using 18O-H2O

In paukes/eee2eye: Calculate evaporation to inflow ratios for lakes using a bunch of assumptions and δ18O-H2O values

Description

This function allows you to calculate the evaporation to inflow (E:I) ratio of a lake based on a few assumptions and its water isotope value.

Usage

eee2eye(df, dL, dI, dP, temp, humid, k)

Arguments

df	dataframe with your values
dL	steady-state lake isotope value (‰)
dI	input/source water isotope value (‰)
dP	precipitation isotope value (‰)
temp	temperature at surface of lake (C)
humid	relative humidity (decimal)
k	influence of seasonality (0.5: highly seasonal; 1: no seasonality)

Examples

ei_input <- data.frame(dL_permille = c(-11.77, -15.67, -18.23),
                       dI_permille = c(-20.7, -18.2, -20.2),
                       dP_permille = c(-23, -28, -32),
                       temp_C = c(14.3, 12.1, 8.9),
                       h_dec = c(0.68, 0.71, 0.58),
                       k = c(0.7, 0.72, 0.65))
eee2eye(ei_input, 'dL_permille', 'dI_permille', 'dP_permille', 'temp_C', 'h_dec', 'k')
