This repository is a live document/analysis needed to write a multi-model manuscript about the PMIP4 midHolocene simulations. It is being coordinated by Chris Brierley and Anni Zhao at University College London. Where people have already agreed to contribute to a particular section, they are mentioned below. But the more-the-merrier, so contact us if you want to help.

The model status is presented in data/ You should be able to run this repository on a Pangeo Binder, but be aware that may take 30mins to load everything up to be ready to use Binder

Manuscript Outline

This is the current plan for the manuscript. Where we have already created the possible figures, they will have hyperlinks to the respective notebooks.

  1. Introduction
    • Importance of MH
    • Brief literature review
    • Purpose of paper: present preliminary results
  2. Methodology
    • PMIP4 overview
    • Summary of midHolocene protocol and differences from PMIP3
    • Participating models
    • Analysis procedure (inc. PaleoCalAdjust by @pjbartlein)
      • Fig 1: impact of calendar adjustment DJF and JJA
  3. Results
  4. Data model comparison (w. Sandy Harrison, Julien Emile-Geay)
    • Comparison with new gradient compilations (Routson et al., 2019 esp. focus on ocean)
      • Fig 10: Change in latitudinal gradients vs data
    • Impact of new terrestrial data synthesis on dmc. Sandy Harrison](
      • Fig 7: comparing Bartlein vs Cleator data sets at sites where both (all variables)
      • Fig 8: Taylor diagrams for all six variables, old data vs new data, different symbols for PMIP3 and PMIP4
      • Fig 9: Benchmarking carpet plot
    • ENSO amplitude in comparison Emile-Geay et al., 2015 compilation by @CommonClimate
      • Fig 11: Changes in annual cycle and interannual variability in pseudocorals in Tropical Pacific
  5. Discussion (w. Julia Hargreaves)
    • Impact of changing boundary conditions and set up (between PMIP4 and PMIP3). e.g. Radiative forcing difference between 280 and 260. Would be nice to have sensitivity runs about vegetation impacts, but that can wait for people to perform the simulations.
    • Future work section - used to highlight upcoming analyses
    • Potential for hydrological palaeobservational constraints
      • Fig 12: scatter plot of MH NAF monsoon vs future response
  6. Summary and Conclusion
