Conjuntool

A free, open source (AGPL) tool for the analysis of GCM data from CMIP5.

Available functions:

  1. GCM Plots: Plot time series of GCM data, and produce monthly or annual time series for download.
  2. GCM Anomalies: Read GCM data and generate \(\Delta T\) Anomalies over a chosen baseline.
  3. Overlay Map: Show an overlay map of the time-period average temperature for the selected model and period selected.

Discalimer:

This is currently running on my self-built server. Please go easy on poor Cubert. Only request a few anomalies at a time!

For now, this data should only be accessed for educational, non-commercial purposes. This may change pending the outcome of Todo #2.

Todo:

  1. Resample: Provide a means to download subsets of data for a given time period and geographical extent. Resampling is easy enough, trying to decide the object to export is the tough part. Perhaps I'll have to learn how to bake a NetCDF file.
  2. Licensing: Double-check any rules regarding the redistribution of the above.
  3. Design/Refactor/Recode: I have a lot of duplciate code, I still need to get the hang of Shiny modules and their implementation. I also need to perform much more robust error handling.
  4. Precipitation etc.: Provide a means of using other variables. For now I don't have an easy way of converting precipitation flux (in \(kg\cdot m^{-2}\cdot s^{-1} = mm\cdot s^{-1}\)) to total (\(mm\)) because the number of seconds in a month is not consistent between models. Given then time is expressed as seconds form an origin, I should be able to do some differencing to get the number of seconds between each month.

Version:

This is version 0.0.3-pre. This is pre-release software. Expect bugs and errors! I have done very little error handling in the code so far.

The source code for this project is available at: https://gitlab.com/ConorIA/conjuntool

Note: The current devel branch will be squashed into an initial commit in a master branch when this hits some kind of stable status.

Why “Conjuntool”?:

The Conjuntool is an open-source “re-imagining” of the UTSC Ensemble tool, a closed, limited-access platform has been used in the UTSC Climate Lab. The restricted nature of the Ensemble tool runs counter to my commitment to use only open-source software and open methodology in my research. I started writing the code that underlies this tool in Tarapoto, Peru. Conjuntool is a portmanteau of “conjunto” (the Spanish word for “ensemble”) and “tool”.
