A National Emission System to Support Air Quality Modelling and Greenhouse Gases Monitoring Efforts in Spain
摘要
We present the “high-Resolution air Emissions Systems to suPport modellIng and monitoRing Efforts” (RESPIRE) project, an initiative aimed at enhancing strategic capabilities for modelling and monitoring atmospheric pollutants and greenhouse gases (GHG) emissions in Spain. RESPIRE is structured in two specific components: RESPIRE-AIR and RESPIRE-CLIMATE. RESPIRE-AIR develops an emission model responsible of performing a spatio-temporal downscaling and speciation processing of the officially reported Spanish emission inventory under the Convention on Long-Range Transboundary Air Pollution. As a result, the model produces gridded (up to 1kmx1km), hourly and speciated emissions to be used as input for the national air quality forecasting system operated by the Spanish Meteorological Office. Detailed local spatial and temporal proxies constructed using data collected at a fine scale are used to reflect the influence of climatological, technological and socio-demographic aspects on the distribution and speciation of anthropogenic emissions. RESPIRE-CLIMATE establishes a national monitoring system for CO2 and CH4 emissions, combining emissions inventory data with observations from ground-based instruments. This system is divided into four fundamental pillars: (P1) a low-latency GHG emissions monitoring system that research-based estimates of anthropogenic emissions at high spatial (1 km) and temporal resolution (daily) with a 2–3 months latency; (P2) a collection of high-resolution GHG emission maps (1kmx1km) consistent with the official Spanish inventory reported under the UNFCCC; (P3) a national GHG observational monitoring network; and (P4) a web application for the visualization, analysis, and downloading of emissions data derived from the first three pillars.
