Abstract. This paper provides a detailed description of the atmospheric conditions characterizing high Himalayas, thanks to continuous observations begun in March 2006 at Nepal Climate Observatory-Pyramid (NCO-P) located 5079 m a.s.l. on southern foothills Mt. Everest, framework ABC-UNEP and SHARE-Ev-K2-CNR projects. The work presents characterization meteorological air-mass circulation NCO-P during first two years activity. mean values pressure, temperature wind speed recorded site were:...
Abstract. The one-year (2001) record of aerosol data from the space borne Moderate Resolution Imaging Spectroradiometer (MODIS) is analyzed focusing on Mediterranean region. MODIS optical thickness standard product (AOT at 550nm) provided over both land and ocean employed to evaluate seasonal spatial variability atmospheric particulate Expected accuracy AOT (±0.05±0.2xAOT) (±0.03±0.05xAOT) ocean. analysis reveals a significant all region, with minimum values in Winter (AOT<0.15) maximum...
Abstract. We provide an atmospheric aerosol characterization for North Africa, Northeastern Atlantic, Mediterranean and Middle East based on the analysis of quality-assured direct-sun observations 39 stations AErosol RObotic NETwork (AERONET) which include at least annual cycle within 1994–2007 period. extensively test apply recently introduced graphical method Gobbi co-authors to track discriminate different types quantify contribution mineral dust.

Abstract. Aerosol spectral measurements by sunphotometers can be characterized three independent pieces of information: 1) the optical thickness (AOT), a measure column aerosol concentration, 2) average dependence, given Angstrom exponent (α), and 3) curvature α (δα). We propose simple graphical method to visually convert (α, δα) contribution fine AOT size aerosols. This information used track mixtures pollution with dust, distinguish growth from cloud contamination observe humidification....
Abstract. Mountainous regions are often considered pristine environments; however they can be affected by pollutants emitted in more populated and industrialised areas, transported regional winds. Based on experimental evidence, further supported modelling tools, here we demonstrate quantify the impact of air masses from Po Valley, a European atmospheric pollution hotspot, to northwestern Alps. This is achieved through detailed investigation phenomenology near-range (a few hundred...
Abstract. Characterizing chemical and physical aerosol properties is important to understand their sources, effects, feedback mechanisms in the atmosphere. This study proposes a scheme classify populations based on spectral optical (absorption scattering). The obtained thanks outstanding set of information particle size composition these contain. variability single scattering albedo (dSSA), extinction, absorption Angstrom exponents (EAE, SAE AAE, respectively) were observed basis two-year...
Abstract. Wildland fires represent the major source of fine aerosols, i.e., atmospheric particles with diameters <1 μm. The largest numbers these occur in Africa, Asia and South America, but a not negligible fraction also occurs Eastern Europe former USSR countries, particularly Russian Federation, Ukraine Kazakhstan. Besides impact large forest fires, recent studies highlighted crucial role played by routine agricultural Russia on Arctic atmosphere. An evaluation over is currently...
Abstract. Chemical and dynamical processes lead to the formation of aerosol layers in upper planetary boundary layer (PBL) above it. Through vertical mixing entrainment into PBL these may contribute ground-level particulate matter (PM); however, date a quantitative assessment such contribution has not been carried out. This study investigates this aspect by combining chemical physical measurements with WRF/Chem (Weather Research Forecasting Chemistry) model simulations. The observations were...
Abstract. In this study, the Weather Research and Forecasting model with online coupled chemistry (WRF-Chem) is applied to simulate an intense Saharan dust outbreak event that took place over Mediterranean in May 2014. Comparison of a simulation using physics-based desert emission scheme numerical experiment simplified (minimal) included highlight advantages former. The was found reproduce well synoptic meteorological conditions driving outbreak: omega-like pressure configuration associated...
Current shipping activities employ about 3% of the world-delivered energy. Most this energy is conveyed by diesel engines. In Europe, release NOx and particulate matter (PM) from expected to equal road-transport one year 2020. This paper addresses a typical central Mediterranean city-port condition evaluate relative contribution local air quality. A 3-year long quality dataset collected at boundary between port Civitavecchia (the major in Italy) city itself was analyzed long-term,...
Abstract This work tackles the problem of automated detection atmospheric boundary layer (BL) height h , from aerosol lidar/ceilometer observations. A new method, Bayesian selective method (BSM), is presented. It implements a statistical inference procedure which combines in statistically optimal way different sources information. Firstly, stratification boundaries are located discontinuities ceilometer backscattered signal. The BSM then identifies discontinuity edge that has highest...
Abstract. The concentrations of neutral and charged sub-3nm clusters their connection to new particle formation (NPF) were investigated during the PEGASOS campaign (7 June–9 July 2012) at San Pietro Capofiume measurement station in Po Valley, Italy. Continuous high detected period, although condensation sink was relatively (median value 1.1 × 10−2 s−1). median cluster 2140 7980 cm−3 size bins 1.5–1.8 1.8–3 nm, majority them electrically neutral.

Abstract. Vertical profiles of aerosol particle optical properties were explored in a case study near the San Pietro Capofiume (SPC) ground station during PEGASOS Po Valley campaign summer 2012. A Zeppelin NT airship was employed to investigate effect dynamics planetary boundary layer at altitudes between ∼ 50 and 800 m above ground. Determined included size distribution, hygroscopic growth factor, effective index refraction light absorption coefficient. The first three parameters used...
Abstract. Investigations on atmospheric aerosols and their sources were carried out in October/November 2013 May/June 2014 consecutively a suburban area of Rome (Tor Vergata) central (near St Peter's Basilica). During both years Saharan dust advection event temporarily increased PM10 concentrations at ground level by about 12–17 µg m−3. Generally, the ambient aerosol was more strongly influenced primary emissions, whereas higher relative contributions secondary particles (sulfate, aged...
Abstract. This work evaluates the impact of trans-regional aerosol transport from Po basin on particulate matter levels (PM10) and physico-chemical characteristics in northwestern Alps. To this purpose, we exploited a multi-sensor, multi-platform database over 3-year period (2015–2017) accompanied by series numerical simulations. The experimental setup included operational (24/7) vertically resolved profiles an automated lidar ceilometer (ALC), integrated properties Sun/sky photometer,...
