Application of degree-day factors for residential emission estimate and air quality forecasting
Results of air quality modelling are strongly influenced by the emission inventory used. This is related to spatial and temporal allocation of emission. In Poland, the share of residential combustion (RC) in total emission of particulate matter is large, and the temporal profile of emission from this sector is influenced by meteorological conditions. Here we show the performance of the WRF-Chem model forecasts, running for the area of Poland with two different approaches to temporal distribution of emission from RC. First, emissions are distributed temporally using the monthly, daily and hourly emission factors provided by GENEMIS project (base run). Second, the model uses the heating degree-day (HDD) approach RC. We show that both approaches result in similar model performance for PM10 and PM2.5. The HDD approach leads to better forecasts for the warm days, whereas the base run forecasts often show too high concentrations of atmospheric pollutants for such periods.
期刊介绍:
IJEP provides an international forum in the field of environment and pollution and addresses early and medium-term challenges involving scientific prediction, modelling and assessment. It focuses on ground-breaking research in the science of environmental pollution, at the early scientific stage. It is one of three key journals which together offer complete coverage of environmental issues: IJETM focuses on technical/engineering, policy and management solutions for environmental problems, and IJGEnvI focuses on future, longer-term environmental scenarios, ecological economics, climate change and biodiversity.
