buildMdz: Empiric equation for minimum temperature used in Mendoza

In anadiedrichs/frost: Prediction of Minimum Temperature for Frost Forecasting in Agriculture

Description

According to Maldonado (see [1]), the empirical equation used in Mendoza to estimate the minimum temperature in the night is:

Tmin = ((Tmax + dew)/2)) - K

, where K is a constant calculated for each place, Tmax: maximum temperature of previous day, dew: dew point in °C, Tmin: is the forecaste minimum temperature. Given an array of the information of dw, tempMax and tmin, this function calculates K constant using linear regression. [1] Ortiz Maldonado, Alberto. Adversidades agrometeorológicas de Mendoza. 1991.

Usage

buildMdz(dw, tempMax, tmin)

Arguments

dw	[°C] Dew Point in °C
tempMax	[°C] Maximum temperature of the previous day
tmin	[°C] Minimum temperature measure that day.

Value

an object of class MdzFrostModel

Examples

# just a random example
dw <- c(-2,-5,2,6,8)
tempMax <- c(10,20,30,25,29)
tmin <- c(-1,-2,3,5,10)
buildMdz(dw,tempMax,tmin)
