Soil Heat Flux Remote Sensing Method from Santanello & Friedl 2003 Python Package

Santanello Soil Heat Flux Python Package

This package provides a Python implementation of the soil heat flux (G) calculation based on the method proposed by Santanello and Friedl (2003). The algorithm estimates soil heat flux as a function of time of day, net radiation, and soil moisture, capturing the diurnal cycle and moisture dependence of land surface energy balance.

Features

• Implements the Santanello & Friedl (2003) soil heat flux (G) calculation using published relationships.
• Accepts both numpy arrays and Raster objects for input data.
• Models diurnal variation and soil moisture dependence of soil heat flux.

Installation

Install the santanello-soil-heat-flux package from PyPi using pip:

pip install santanello-soil-heat-flux

Usage

Import the main function and use it with your raster or numpy array data:

from santanello_soil_heat_flux import santanello_soil_heat_flux

G = santanello_soil_heat_flux(seconds_of_day, Rn, SM)

Where:

• seconds_of_day: Time in seconds since midnight
• Rn: Net radiation in W/m²
• SM: Soil moisture in m³/m³
