Biosphere Atmosphere Climate Interactions lab 2025

Go to the Theory and Concepts page

This page contains the laboratory materials for the BACI2025 course, specifically covering the sections I oversee. The laboratory sessions build upon concepts from the hydrology class while extending into more advanced simulations, including applications of the GEOSPACE system.  GEOSPACE is based upon GEOframe is an open-source, component-based hydrological modeling framework developed primarily by researchers in Italy. It's designed to be modular and flexible, allowing researchers to combine different hydrological processes and models.

Installations
Generalities about the Object Modelling System

OMS3 (Object Modeling System 3) is a Java-based environmental modeling framework developed by the U.S. Geological Survey (USGS) and Colorado State University. It's designed to facilitate the development, integration, and deployment of environmental and agricultural models.

OMS Project that will be used
WHETGEO specifically focuses on simulating the coupled processes of water and heat transport, which are crucial for understanding: Soil moisture dynamics, Evapotranspiration processes, Energy balance at the land surface, Groundwater-surface water interactions, Snow and ice processes (where temperature is critical)
  • Exploring a WHETGEO project. Everything is explained in the WHETGEO1D_RichardsCoupled_Computational_grid notebook (Vimeo2025)
  •  Please also browse directly the files:
    • The grid file: ex00_grid.csv , Initial Conditions: ex00_ic.csv, Parameters: (for van Genuchten): Richards_VG.csv, Dictionary: dictionary.csv (Vimeo2025)
    • WHETGEO1D.sim (Vimeo2025)
  • Analysis of WHETGEO1D.sim (Vimeo2025)
  • To run WHETGEO use the Runner_WHETGEO.ipynb notebook (Vimeo 2025)
    • Please observe that the oms.py file needs to be in the same folder than the Notebook
    • During the course a more solid solution was provided here.
  • How to visualize and interpret the data through the Visualize_output.ipynb Notebook (Vimeo 2025)
  • Utilities:
    • To proper formatting (according to OMS3) rainfall files, peruse the TimeSeriesFormatter.ipynb Notebook (Vimeo2025)
    • How to create an empty TimeSeries using TimeSeriesCreator.ipynb (Vimeo2025) 
RADIATION ESTIMATION is preliminary to any Evapotranspiration estimation since our models use it as input. The estimation of radiation, as it results from the theory, needs a few GIS operations to determine the sky view factor and the aspect of the terrain in the point of interest. These operation for the present exercise are skipped and pre-analyzed data are provided. 
  • Please see the 05_NET.sim file in the project's simulation folder (Vimeo2025)
  • Inputs are in Input_Radiation.ipynb (Vimeo2025)
  • Outputs are in the Output_Radiation.ipynb (Vimeo2025)
  • The simulation runner is Runner_NetRadiation.ipynb (Vimeo2025)
GEOET  is a group of  components within GEOframe that focuse specifically on evapotranspiration (ET) modeling. At present GEOET includes three main estimator of ET: The Priestley-Taylor, the Penman-FAO and the Prospero one.  
  • Exploring a GEOET project
GEOSPACE, the Soil Plant Atmosphere Continuum Estimator in GEOframe (GEOSPACE) is presented in this paper, in particular the one-dimensional development, GEOSPACE-1D. GEOSPACE  (D'Amato et al., 2025) is a sophisticated modeling framework designed to simulate the complex interactions within the soil-plant-atmosphere continuum (SPAC) system.
