The Joint UK Land Environment Simulator (JULES), model description – Part 1: Energy and water fluxes

TLDR

JULES builds on the Met Office Surface Exchange Scheme (MOSES) and has been the basis for many high‑profile land‑surface and climate studies over the last decade. This manuscript describes the energy and water components of the new community land surface model JULES. JULES is a modular land surface model that can operate standalone with observed forcing or be coupled to an atmospheric global circulation model, providing a flexible platform aligned to physical processes. The JULES model has been coupled to the Met Office Unified Model (UM), offering the research community a unique opportunity to improve both world‑leading operational weather forecasting and climate change prediction systems.

Abstract

Abstract. This manuscript describes the energy and water components of a new community land surface model called the Joint UK Land Environment Simulator (JULES). This is developed from the Met Office Surface Exchange Scheme (MOSES). It can be used as a stand alone land surface model driven by observed forcing data, or coupled to an atmospheric global circulation model. The JULES model has been coupled to the Met Office Unified Model (UM) and as such provides a unique opportunity for the research community to contribute their research to improve both world-leading operational weather forecasting and climate change prediction systems. In addition JULES, and its forerunner MOSES, have been the basis for a number of very high-profile papers concerning the land-surface and climate over the last decade. JULES has a modular structure aligned to physical processes, providing the basis for a flexible modelling platform.
