NEWA Open-Source Model-Chain v1.0

This report provides a brief user’s manual for the first release of the NEWA open-source model-chain. The document is associated to a public git repository that will be updated throughout the rest of the project.;The objective of this release is to allow early-adopters of the model-chain to start testing the open-source code and, eventually, provide feedback to the NEWA developers about usability, possible bugs, robustness, etc.;The repositories consist of: CFDWind3 OpenFOAM libraries to run atmospheric-boundary layer microscale simulations driven by mesoscale inputs. Tutorial test case based on the GABLS3 diurnal-cycle benchmark. Repository available at:;https://github.com/iat-cener/CFDWindAdditional test cases will be added in the future as new benchmarks are produced based on the experiments of the project. ;The report provides an overview of the model-chain context and its intended use followed by a description of CFDWind3 libraries. Finally, an outlook on future developments is provided.
