LMR Turbo (LMRt)

LMR Turbo (LMRt) is a lightweight, packaged version of the Last Millennium Reanalysia (LMR) framework, inspired by originated by Professor Hakim. LMRt aims to provide following extra features:

  • a package that is easy to install and import in scripts or Jupyter notebooks

  • modularized workflows at different levels:

    • the low-level workflow focuses on the flexibility and customizability

    • the high-level workflow focuses on the convenience of repeating Monte-Carlo iterations

    • the top-level workflow focuses on the convenience of reproducing an experiment purely based on a given configuration YAML file

  • convenient visualization functionalities for diagnosis and validations (leveraging the Series and EnsembleSeries of the Pyleoclim UI)
