Introduction

Paleoclimate data often proves challenging to interpret, and modeling these archives using a process-based approach has recently emerged as one way to better constrain the climatic controls on these records. A suite of python-based models for these archives was recently published by Dee et al., 2015. To expand use in both the climate community and promote PRYSM as a teaching tool, we have developed a user-friendly GUI for these models. In doing so, we hope to provide a lasting service to the paleoclimate community, as well as for geoscience education.

Version 1.0 includes coral, cellulose, and icecorePSM models and is only available for macOS.

Getting Started

1. Download the executable file here
2. Open the executable file. This can be done by clicking on the file.
   • The executable file may take a while to load.
   • If the executable file is unable to open, you may have to change the permissions on the file.
     • Go into the command line on a Mac (for example, terminal).
     • Navigate to the folder where the downloaded executable is located. (More on command line navigating here.)
     • Type in the instructions "chmod 755 PRYSM-GUI".
     • Try opening the excutable file. The executable file should now be openable.
   • If the executable file is still unable to open, try lowering the security preferences.
     • Open System Preferences
     • Click "Security & Privacy"
     • Click "Open Anyway"
     • The executable file should now be openable.

Example Data Files

We have included example data csv files as a reference for formatting your own data and for getting familiar with the GUI. This is the same data that was used in the paper.

• Coral Data
• Cellulose Data
• Icecore Data
