Innovative satellite data solutions  

GHGSat has developed an innovative capability for validated dynamic three-dimensional greenhouse gas emissions estimation on a global scale using data from its own satellites and third-party satellites. The project implemented a mathematical model for global methane emission rate estimation with components for the three-dimensional simulation of sources and sinks (both anthropogenic and naturogenic) as well as chemical transport and atmospheric propagation. The model was validated both analytically (model checks based on posterior predictive distribution) and against independent third-party methane inventories. The validated emission rate estimator can be adapted for operational solutions to address Sustainable Development Goal 13 (take urgent action to combat climate change and its impacts).
