CarboTope

Beta

CarboTope is a new simple carbon cycle model (designed for teaching, not research, and still in beta) and accompanying website, aimed at informed users who want to better understand how seasonal patterns, hemispheric differences, and different isotopes all interact. It is free and open source.

Open CarboTope

The model starts when you open it. The first view can take about 30 seconds.

The CarboTope app open at its first tab, the Keeling Curve: modelled and measured CO₂ at Mauna Loa and the South Pole from 1958 to 2024, with the year range, hemisphere and measurement controls on the left.

In the app

Beta teaching software, not peer-reviewed. The app's “Known issues” tab lists where the model and the measurements disagree.
