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

Description Usage Arguments Examples

View source: R/eee2eye.R

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

1
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)
