Investigation of meteorological measurements along a 45 m tower at Dome C on the high East Antarctic Plateau revealed two distinct stable boundary layer (SBL) regimes this location. The first regime is characterized by strong winds and continuous turbulence. It results in full vertical coupling temperature, wind magnitude direction SBL. second weak winds, associated with turbulent activity very temperature inversions reaching up to 25 K lowest 10 m. Vertical profiles are generally...
In February 2017 the “Carbonaceous Aerosol in Rome and Environs (CARE)” experiment was carried out downtown to address following specific questions: what is color, size, composition, toxicity of carbonaceous aerosol Mediterranean urban background area Rome? The motivation this lack understanding types are responsible for severe risks human health posed by particulate matter (PM) pollution, how aerosols influence radiative balance. Physicochemical properties were characterised, relevant...
Wherever a loose bed of sand is subject to sufficiently strong winds, aeolian dunes form at predictable wavelengths and growth rates. As mature coarsen, however, their trajectories become more idiosyncratic; nonlinear effects, sediment supply, wind variability geologic constraints increasingly relevant, resulting in complex history-dependent dune amalgamations. Here we examine fundamental question: do stop growing and, if so, what determines ultimate size? Earth's major seas are populated by...
Abstract. Regional climate model MAR (Modèle Atmosphérique Régional) was run for the region of Dome C located on East Antarctic plateau, during summer 2011–2012, in order to refine our understanding meteorological conditions OPALE tropospheric chemistry campaign. A very high vertical resolution is set up lower troposphere, with a grid spacing roughly 2 m. Model output compared temperatures and winds observed near surface from 45 m tower as well sodar radiation data. generally good agreement...
Air temperature (Ta) measurements are crucial for characterizing phenomena ike the urban heat island (UHI), which can create critical conditions in cities during summer. This study aims to develop a machine earning-based model, namely gradient boosting, estimate Ta from geostationary satellite ST data and apply these estimates investigate UHI dynamics. Using Rome, Italy, as case study, model was trained with 15 weather stations, taking multi-temporal values (instantaneous agged up 4 h)...
Abstract The Boundary layer Air Quality-analysis Using Network of Instruments (BAQUNIN) supersite is presented. site has been collecting pollutant concentrations and meteorological parameters since 2017. Currently, BAQUNIN consists three observation sites located in the city center Rome (Italy), neighboring semirural rural areas. To best our knowledge, one first observatories world to involve several passive active ground-based instruments installed multiple locations, managed by different...
The Mediterranean is recognized among the most responsive regions to climate change, with annual temperatures projected increase by 1–5 °C until 2100. Large cities may experience an additional stress discomfort due Urban Heat Island (UHI) effect. In present study, WRF-ARW numerical weather prediction model was used investigate change impact on UHI for two cities, Rome and Thessaloniki. For this purpose, three 5-year time-slice simulations were conducted (2006–2010, 2046–2050, 2096–2100)...
The mixing-layer height is estimated using measurements from a high resolution surface-layer sodar run at the French-Italian station of Concordia Dome C, Antarctica during summer 2011–2012. temporal and spatial allows monitoring evolution whole diurnal cycle, i.e. very shallow nocturnal boundary layer followed by typical daytime growth. behaviour height, variable between about 10- 300 m, analyzed as function mean turbulent structure layer. Focusing on convective cases only, retrieved values...
Two mini neutron monitors are installed at Concordia research station (Dome C, Central Antarctica, <TEX>$75^{\circ}06^{\prime}S$</TEX>, <TEX>$123^{\circ}23^{\prime}E$</TEX>, 3,233 m.a.s.l.). The site has unique properties ideal for cosmic ray measurements, especially the detection of solar energetic particles: very low cutoff rigidity < 0.01 GV, high elevation and poleward asymptotic acceptance cones pointing to geographical latitudes > <TEX>$75^{\circ}S$</TEX>. instruments consist a...
Anomalous deviations from the Beer-Lambert law have been observed for a long time in wide range of application. Despite all attempts, reliable and accepted model has not provided so far. In addition, some cases attenuation radiation seems to follow hyperbolic more than an exponential extinction law. Starting probabilistic interpretation based on Poissonian distribution events, this paper we consider classical introducing weighted version The generalized is able account both sub or...
Aims. An experiment was set up at the Concordia station in Antarctica during winter-over period 2012 to determine behaviour of atmospheric optical turbulence lower part boundary layer. The aim study influence and weather conditions on quality astronomical observations. is characterised by high images thanks very low seeing values. surface layer interior winter stably stratified with differences temperature between top inversion, which reach 20−35°C. In spite this strong static stability,...
<p>One year field experiment has started on December 2011 at the French - Italian station of Concordia Dome C, East Antarctic Plateau. The objective is study surface layer turbulent processes under stable/very stable stratifications, and mechanisms leading to formation warming events. A sodar was improved achieve vertical/time resolution needed these processes. system, named Surface Layer (SL-sodar), may operate both in high vertical (low range) low (high modes. <em>In...
In the period January–February 2014, observations were made at Concordia station, Dome C, Antarctica to study atmospheric turbulence in boundary layer using a high-resolution sodar. The structure was observed beginning from lowest height of about 2 m, with vertical resolution less than m. Typical patterns diurnal evolution spatio-temporal detected by sodar are analyzed. Here, we focus on wavelike processes within transition stable unstable stratification occurring morning hours. Thanks...
Abstract. A 10-year record of oxygen and hydrogen isotopic composition precipitation is presented here: from 2008 to 2017, 1483 daily samples were collected year-round on a raised platform at Concordia Station, East Antarctica. Weather data retrieved the Italian Antarctic Meteo-Climatological Observatory automatic weather station (AWS), while ERA5 was used estimate total precipitation. The δ–temperature relationships moderately high for (r2=0.63 0.64 δ18O δ2H, respectively) stronger using...
