Abstract: The enCore Community Land Model (eCLM) is a Fortran-based HPC software for simulating the biogeophysical, biogeochemical, and hydrological processes on Earth's land surface. These physical processes are derived from the Community Land Model version 5 (CLM5)—a land surface model developed by the National Center for Atmospheric Research in USA. While eCLM take most of its scientific features from CLM5, it differs mainly in its software architecture, which has been designed to readily integrate into a modular Earth system modeling platform. This presentation showcases the software refactoring efforts involved in transforming CLM5, a mature HPC software for land surface modelling, into eCLM. Notably, this RSE work contributes to a larger ongoing effort towards a next-generation modular Earth system modeling platform. eCLM was initiated in 2020 and is being constantly tested (e.g. through continuous integration and deployment practices) and improved (e.g. by introducing new modelling features such as vegetation processes and land management) to serve the research activities at the Agrosphere Institute in Jülich Research Centre, Germany.
