Temporally resolved and speciated atmospheric emission inventories are essential for air quality models to accurately simulate the chemical transformation of pollutants in the atmosphere. This study presents a detailed catalogue of temporal and speciation emission profiles developed for Spain, which is integrated into the High-Elective Resolution Modelling Emission System delta version (HERMES_Δ). HERMES_Δ is a system that processes the official Spanish emission inventory for use in the national air quality modelling system maintained by the Spanish Meteorological Agency. The constructed temporal profiles include sector- and region-specific monthly, weekly, and hourly profiles for over 224 activities, based on activity data and spatial dependencies driven by climatological and socio-demographic factors. The collection of speciation profiles incorporates up-to-date European and national information, allowing the disaggregation of non-methane volatile organic compound (NMVOC) emissions into individual chemical species. The temporally resolved and speciated emissions were analyzed and compared with those reported by the Copernicus Atmosphere Monitoring Service European Regional inventory (CAMS-REG). Key discrepancies were identified, primarily because the CAMS-REG profiles do not account for regional and activity-specific variations within Spain.

摘要

Temporally resolved and speciated atmospheric emission inventories are essential for air quality models to accurately simulate the chemical transformation of pollutants in the atmosphere. This study presents a detailed catalogue of temporal and speciation emission profiles developed for Spain, which is integrated into the High-Elective Resolution Modelling Emission System delta version (HERMES_Δ). HERMES_Δ is a system that processes the official Spanish emission inventory for use in the national air quality modelling system maintained by the Spanish Meteorological Agency. The constructed temporal profiles include sector- and region-specific monthly, weekly, and hourly profiles for over 224 activities, based on activity data and spatial dependencies driven by climatological and socio-demographic factors. The collection of speciation profiles incorporates up-to-date European and national information, allowing the disaggregation of non-methane volatile organic compound (NMVOC) emissions into individual chemical species. The temporally resolved and speciated emissions were analyzed and compared with those reported by the Copernicus Atmosphere Monitoring Service European Regional inventory (CAMS-REG). Key discrepancies were identified, primarily because the CAMS-REG profiles do not account for regional and activity-specific variations within Spain.
