One of the goals of the Paleoclimate Working Group is to allow the community to address scientific questions about past climates in Earth history using the CESM model. To that end we include useful tools that are designed to modify the forcing and input files for paleoclimate applications.
Before you begin ...
If you are considering a Paleoclimate project using the CESM model you may find it useful to answer the following questions. We strongly recommend that you complete the exercises in the CESM tutorial and run a short 'vanilla' pre-industrial simulation of the CESM model before you start working on your paleoclimate simulation.
- What scientific question do you plan to investigate with the CESM?
- The current release of the CESM may not resolve all the necessary processes nor have adequate resolution critical for your climate study.
- What time period do you want to simulate?
- The boundary conditions and forcing files included as part of the CESM release pertain to modern time periods: pre-industrial, present day and future scenarios. Configuring the CESM for past time periods is the responsibility of the investigator.
- What configuration of CESM do you plan to use?
- Your research may allow a reduced model configuration. For example, you may be able to implement active land and atmosphere component models driven by prescribed SST and sea ice distributions. This may be a good place to start if you have limited computational time and storage allocation. What computer will you use to run your simulations?
- Do you have experience running or analyzing output from the CESM?
- Running an "out-of-the-box" (OTB) pre-industrial CESM simulation and completing the CESM Tutorial are prerequisites for configuring a paleoclimate simulation.
- What computer will you use to run your simulations? Do you have allocated computer time and storage on the NCAR-Wyoming Supercomputers?
- Running the CESM at any resolution or configuration is computationally expensive and produces large amounts (Giga to Tera bytes) of output. This means you will need supercomputer access and storage space to carry out your simulations.
We ask that you submit questions to the CESM Discussion Forum so that other users may contribute to or benefit from the discussion.
