growing_degree_day
(tmin, tmax, base_min, base_max)[source]¶ Growing degree days (GDD).
GDD, also called growing degree units (GDUs), are a heuristic tool in phenology and are a measure of heat accumulation used by agricultural scientist and farmers to predict plant growth stage.
Parameters: - tmin – minimum temperature of the day (°C)
- tmax – maximun temperature of the day (°C)
- base_min – base temperature (°C)
- base_max – maximum base temperature (°C)
Returns: Growing degree days (°C)

modified_henderson_moisture
(t, rh, a, b, c)[source]¶ Equilibrium Moisture Equation Constants.
Empirical equilibrium moisture content equation: modified Henderson equation. This equation can be used to calculate equilibrium moisture content or equilibrium relative humidity with the constants below for typical products.

modified_henderson_relative_humidity
(t, m, a, b, c)[source]¶ Equilibrium Moisture Equation Constants.
Empirical equilibrium moisture content equations are the modified Henderson equation and the Chung-Pfost equation. These equations can be used to calculate equilibrium moisture content or equilibrium relative humidity with the constants below for typical products.
