Gross primary production (GPP) describes the conversion of CO₂ to carbohydrates and can be seen as a filter for our atmosphere of the primary greenhouse gas CO₂. We developed VODCA2GPP, a GPP dataset that is based on vegetation optical depth from microwave remote sensing and temperature. Thus, it is mostly independent from existing GPP datasets and also available in regions with frequent cloud coverage. Analysis showed that VODCA2GPP is able to complement existing state-of-the-art GPP datasets.
