“…Concentrations of nitrogen oxides (NO and NO 2 ) were negatively related to the NAOI in the city of Gothenburg, west Sweden during the winter months for the period 1997-2006 [19]. In our multivariate model, concentrations of ozone, PM 10 and CO were included but we did not adjust for the impact of other pollutants.…”

“…As the quintiles of the daily NAOI were −1.01, −0.49, −0.06 and 0.43 during the study period and the non-linear impact of the NAO is probable, we used the NAOI as categorical variable with categories: ≤−1, (−1, −0.5], (−0.5, 0], (0, 0.5] and >0.5. As confounders, we used the non-linear variables of air temperature (T, • C), wind speed (WS, kt), barometric pressure (BP, hPA) and relative humidity (RH, %), low and active-stormy geomagnetic activity levels, high-speed solar wind (HSSW), daily concentrations of ozone and PM 10 and the highest 8-h moving average of CO concentration. These variables are described in more detail in previous publications [15,16].…”

Abstract:The North Atlantic Oscillation (NAO) is the most prominent pattern of atmospheric variability over the middle and high latitudes of the Northern Hemisphere, especially during the cold season. It is found that "weather types" are associated with human health. It is possible that variations in NAO indices (NAOI) had additional impact on human health. We investigated the association between daily emergency ambulance calls (EACs) for exacerbation of essential hypertension and the NAOI by using Poisson regression, adjusting for season, weather variables and exposure to CO, particulate matter and ozone. An increased risk of EACs was associated with NAOI < −0.5 (Rate Ratio (RR) = 1.07, p = 0.013) and NAOI > 0.5 (RR = 1.06, p = 0.004) with a lag of 2 days as compared to −0.5 ≤ NAOI ≤ 0.5. The impact of NAOI > 0.5 was stronger during November-March (RR = 1.10, lag = 0, p = 0.026). No significant associations were found between the NAOI and EACs during 8:00-13:59. An elevated risk was associated during 14:00-21:59 with NAOI < −0.5 (RR = 1.09, p = 0.003) and NAOI > 0.5 (RR = 1.09, p = 0.019) and during 22:00-7:59 with NAOI < −0.5 (RR = 1.12, lag = 1, p = 0.001). The non-linear associations were found between the NAO and EACs. The different impact of the NAO was found during the periods November-March and April-October. The impact of the NAOI was not identical for different times of the day.

“…For comparison in Central Europe the highest PNC values in this size range were measured at the K-Puszta and Kosetice stations, 2 700 and 2 420 cm -3 , respectively. It should be considered that in clean environments the PNC concentrations usually decrease during the autumn [29,34], and in the Aukštaitija IMS dataset the autumn data was underrepresented. Collecting more data from the SMPS measurement in autumn would have decreased PNC values for the whole campaign, in general.…”

Aerosol particle observations are needed to determine the conditions of particle formation and growth in different environments. This research focuses on new particle formation (NPF) events in the hemi-boreal forest environment at the Aukštaitija Integrated Monitoring Station (IMS) (55°26ʹN and 26°04ʹE, 170 m above the sea level). The parameterisation of aerosol particle Nucleation I (3–10 nm), Nucleation II (10–20 nm) and Aitken (20–100 nm) modes was performed, their inputs to the total particle number concentration (PNC) and distribution were assessed. It has been estimated that around 40% of days in spring and 22% in summer were NPF event days. The highest contribution of Nucleation mode I aerosol particles was observed in June, reaching up to 38% of the total PNC values. The mean growth rate (GR) and condensation sink (CS) values at the Aukštaitija IMS in April and May were 2.9 nm·h–1, 1.30·10–3 s–1 and 5.3 nm·h–1, 1.35·10–3 s–1, respectively. The GR and CS values were well in agreement with the results obtained from other hemi-boreal forest sites in the Baltic Sea region.

“…Several studies investigated the presence and variability of trace gases and aerosol particles in the Baltic Sea region with in-situ ground observations (Kikas et al, 1996;Ku smierczyk-Michulec et al, 2001;Ovadnevait_ e et al, 2007;Kikas et al, 2008) and shipborne observations (Plau skait_ e et al, 2017). The influence of intense marine traffic along the shipping corridors on the presence and properties of atmospheric pollutants (defined as 'shipping corridor effect'; Schlager et al, 2006) in the Baltic Sea was assessed from coastal ground based observations only (Kecorius et al, 2016;Ausmeel et al, 2019).…”

The influence of shipping on air quality over the Southern Baltic Sea was investigated by characterizing the horizontal and vertical distribution of aerosols and trace gases using airborne measurements in the summer of 2015. Generally, continental and anthropogenic emissions affected the vertical distribution of atmospheric pollutants, leading to pronounced stratification in and above the marine boundary layer and controlling the aerosol extinction. Marine traffic along the shipping corridor "Kadet Fairway" in the Arkona Basin is shown to influence the presence and properties of both trace gases and aerosol particles in the lowest atmospheric layer. Total particle number concentration and NO y mixing ratio increased in the corridor plumes, relative to background, by a factor 1.55 and 3.45, respectively. Titration, triggered by the enhanced presence of nitrogen compounds, led to a median ozone depletion of 19% in the corridor plumes. The enforcement of the Sulphur Emission Control Area (SECA) might be responsible for the minor sulphur dioxide increase (20%) in the corridor plumes. Ship traffic caused a minor enhancement of black carbon mass concentration, estimated to be around 10%. The study of individual ship plumes indicated that ship emitted aerosol was substantially different from background aerosol: fresh ship exhaust was preferentially enriched in aerosol particles with diameters below 100 nm and in black carbon particles with core diameters above 300-400 nm. With the present work the impact of marine traffic on the concentration and properties of atmospheric components within the marine boundary layer over the open water of the Southern Baltic Sea is assessed with airborne observations for the first time. Due to the high uncertainty affecting the estimations of ship emissions, this dataset represents a valuable reference for the assessment of ship emission inventories and related environmental-climatic impacts on the Southern Baltic Sea.
