Advanced Terrestrial Simulator

The Advanced Terrestrial Simulator is a code for solving ecosystem-based, integrated, distributed hydrology.

Capabilities are largely based on solving various forms of Richards equation coupled to a surface flow equation, along with the needed sources and sinks for ecosystem and climate models. This can (but need not) include thermal processes (especially ice for frozen soils), evapo-transpiration, albedo-driven surface energy balances, snow, biogeochemistry, plant dynamics, deformation, transport, and much more.

ATS is a suite of physics processes built for Amanzi. As such documentation is split between process documentation here and framework documentation in Amanzi. Links across the related projects attempt to build a uniform interface for the user.
