ESD Ideas: Near real-time preliminary detection of carbon dioxide source and sink areas using a Laplacian filter

Abstract. The constant rise in atmospheric CO2 concentrations is warming the planet and causing climate change. Here, we detect ecosystem areas with weighty changes in the CO2 concentration using digital filtration, similar to image processing techniques, to identify terrestrial CO2 sources and sinks. This approach may improve CO2 monitoring capabilities and enable near real-time detection of CO2 sources and sinks.
