“…The relevant 5-year measurements study also showed an increase of 80 % in BC due to increased wood burning (Paraskevopoulou et al, 2014). The chemical footprint of these smog events has been well established via specialized aerosol measurements, e.g., significant correlations between PM 2.5 and levoglucosan, or high fine mode particulate potassium, demonstrating that, during wintertime, wood burning in Athens could be responsible for PM 2.5 levels higher than 45 µg m −3 (Fourtziou et al, 2017;Paraskevopoulou et al, 2014).…”

“…Thissio is an urban background site, representative of Athens' average atmospheric load. Details of the site are provided in Paraskevopoulou et al (2015) and Fourtziou et al (2017). For the needs of this modeling study, measurements were taken from the campaign in winter -2014(16 December 2013to 21 February 2014, during which unique datasets of wood burning indicators were acquired (Fourtziou et al, 2017).…”

“…Fuller et al (2013) reported on aerosol (PM 10 ) contributions from residential wood burning (hereafter also called "RWB smog") in three major European cities: London, Paris and Berlin and found that, during winter, RWB makes an important contribution to breaches of the daily mean EU limit and PM 10 contribution may surpass that of road traffic. In Portugal, wood combustion is estimated to comprise 60 % of residential energy use but to account for almost 99 % of domestic PM 10 emissions (Borrego et al, 2010).…”

“…In Greece, the respective increase on the non-solid fuel price was in the range of 40-60 %. The high market price together with the limited financial capacity of many households has resulted in an excessive use of biomass for domestic heating (Sarigiannis et al, 2014;Fourtziou et al, 2017).…”

“…The comprehensive, online-coupled, modeling system COSMO-ART (COnsortium for SMall-scale MOdelingAerosols and Reactive Trace gases) was used to quantify the effect of wood burning on aerosol levels and aerosol chemistry as well as on radiation during this period. Detailed chemical measurements of concentrations, speciation and fractions related strictly to wood burning were available from the longest winter measuring campaign of RWB smog to date (e.g., Paraskevopoulou et al, 2014;Fourtziou et al, 2017). Within this paper we want to address the following topics: 1. assessment of the emission data from RWB, 2. contribution of RWB to the total aerosol load and chemistry, 3. calculation of the optical properties of RWB aerosol and 4. impact of RWB smog on radiation and feedbacks on atmospheric composition.…”

Abstract. For the past 8 years, Greece has been experiencing a major financial crisis which, among other side effects, has led to a shift in the fuel used for residential heating from fossil fuel towards biofuels, primarily wood. This study simulates the fate of the residential wood burning aerosol plume (RWB smog) and the implications on atmospheric chemistry and radiation, with the support of detailed aerosol characterization from measurements during the winter of 2013-2014 in Athens. The applied model system (TNO-MACC_II emissions and COSMO-ART model) and configuration used reproduces the measured frequent nighttime aerosol spikes (hourly PM 10 > 75 µg m −3 ) and their chemical profile (carbonaceous components and ratios). Updated temporal and chemical RWB emission profiles, derived from measurements, were used, while the level of the model performance was tested for different heating demand (HD) conditions, resulting in better agreement with measurements for T min < 9 • C. Half of the aerosol mass over the Athens basin is organic in the submicron range, of which 80 % corresponds to RWB (average values during the smog period). Although organic particles are important light scatterers, the direct radiative cooling of the aerosol plume during wintertime is found low (monthly average forcing of -0.4 W m −2 at the surface), followed by a minor feedback to the concentration levels of aerosol species. The low radiative cooling of a period with such intense air pollution conditions is attributed to the timing of the smog plume appearance, both directly (longwave radiation increases during nighttime) and indirectly (the mild effect of the residual plume on solar radiation during the next day, due to removal and dispersion processes).
