IG3IS Webinar Series (Q3-Q4, 2025): A national GHG emission monitoring system to support policy makers and modelling efforts in Spain - current status and achievements

The RESPIRE- CLIMATE (high-Resolution air Emissions Systems to support modeling and monitoring Efforts) project has the goal of developing and deploying a Spanish national CO2 and CH4 emissions monitoring system that combines information from high resolution bottom-up inventories with observations derived from ground-based instruments. The resulting system will allow: i) providing detailed and low latency emission information at a sectoral resolution and spatial (1kmx1km) and temporal (daily) scales that are relevant from national to urban decision making, and ii) expanding the current national GHG observational network to main metropolitan urban areas, namely Madrid and Barcelona, which currently remain unmonitored in an operational way. A dedicated web app is produced to visualize and facilitate the access to the resulting GHG emission products, serving the need for detailed GHG emission information on a national, subnational and urban level. The results of RESPIRE-CLIMATE will support scientific and modelling efforts, such as inversion modelling and data assimilation, as well as decision makers, helping to guide efforts in the design of effective mitigation policies.
