Calculate soil matric potential for Oklahoma Mesonet data

Description

Calculate soil matric potential from delta-T soil temperature change data from the Oklahoma Mesonet using the equation from Zhang et al (2019) <doi:10.2136/sssaj2018.12.0481>: MP = 2083/(1+ exp(-3.35*(Tref-3.17))) where Tref is the measured delta-T data

Usage

mnet_calc_mp(data)

Arguments

data	a data frame that contains columns for delta-T temperature change data (i.e. TR05, TR25, TR60, TR75)

Value

a data frame containing new columns with matric potential (kPa) for each column of delta-T temperature change data.

Examples

mesonet_data <- data.frame(TR05 = 3.17, TR25 = 2.17, TR60 = 2.0, TR75 = 1.0)
