double_sine: Compute the degree day from temperature data.

In jmzobitz/degreeDay: Code to compute degree days for R

Description

double_sine Computes the degree days from temperature data, using interpolation from min and max temperature.

Usage

double_sine(min_temp, max_temp, min_temp_lag, t_L, t_U)

Arguments

min_temp	Minimum daily temperature
max_temp	Maximum daily temperature
min_temp_lag	The next day's minimum daily temperature
t_L	Lower bound on the temperature
t_U	Upper bound on the temperature

Value

Degree day from the list of numbers.

For the equations to compute the degree day: http://ipm.ucanr.edu/WEATHER/ddds_tbl.html. Because this is done over a 12 day period, we have an extra minimum temperature to compute, hence the extra minimum temperature

Examples

double_sine(10,15,12,11,16)
