The Program for Coupled Human and Earth Systems (PCHES) is a project, funded by the U.S. Department of Energy, looking to create a state-of-the-art framework of computational tools that will help to assess the impacts of weather-related variability and change.

Since models are typically operated independently of one another, this project seeks to link a large multidisciplinary team from 10 different institutions in order to integrate multiple existing models to capture important energy-water-land interactions and feedbacks between natural and human systems. Understanding the connections and interactions among the energy, water, and land systems is crucial to achieving a comprehensive, holistic view for the entire integrated system.
