GEOSPACE-1D: A Modular Object-Oriented Framework for Soil-Plant-Atmosphere Continuum Modeling in the Earth's Critical Zone
GEOSPACE-1D: A Modular Object-Oriented Framework for Soil-Plant-Atmosphere Continuum Modeling in the Earth's Critical Zone
The soil-plant-atmosphere continuum (SPAC) encompasses complex, interconnected processes that govern water, energy, and matter exchange. Traditional modeling approaches struggle with the diversity of physical formulations and rapid evolution of SPAC science. We present GEOSPACE (v1.2.9), a component-based framework leveraging object-oriented programming (OOP) principles to enable flexible, extensible SPAC modeling. The framework comprises three main components: WHETGEO (soil water flow using Richards equation), GEOET (evapotranspiration (ET) with multiple model options), and BrokerGEO (coupling component). Key innovations include bidirectional feedback between infiltration and evapotranspiration, multiple stress factor formulations, and a software architecture that allows model extensions without modifying existing validated code. Validation using the Spike II lysimeter experiment demonstrates excellent mass balance closure and reveals that neglecting ET-infiltration coupling overestimates groundwater recharge. The open-source framework adheres to FAIR principles and provides a foundation for reproducible, transparent SPAC research.
