diffusivity {neonSoilFlux}

Compute soil diffusivity

Description

Given a tidied data frame of soil measurements (from interpolate.R), compute the diffusivity in a given soil layer

Usage

diffusivity(
  temperature,
  soil_water,
  pressure,
  temperature_err,
  soil_water_err,
  pressure_err,
  zOffset,
  porVol2To20
)

Arguments

temperature

Required. Soil temperature (degrees C)

soil_water

Required. Soil water content

pressure

Required. Barometric air pressure (kilopascal)

temperature_err

Required. Reported Soil temperature error (degrees C)

soil_water_err

Required. Reported Soil water content error

pressure_err

Required. Reported Barometric air pressure error (kilopascal)

zOffset

Required. Measurement level in cm.

porVol2To20

Required. Porosity of the 0-20 mm fraction (cm3 cm-3). Assumes no pores within rocks.

Value

A value of the computed diffusivity
