Abstract. Saharan Dust Outbreaks frequently hit the Mediterranean Basin, lasting for a few days. These phenomena have various implications ecosystem of entire basin, affecting atmosphere, lithosphere, biosphere, hydrosphere, and cryosphere. Moreover, they cause numerous hazards to human society, especially concerning environment health, are particularly significant people living in “Dust Belt” around Sahara, including nearby areas such as Basin. This study demonstrates that continuous dust...

Abstract. Understanding the evolving patterns of intense rainfall in Mediterranean under climate change is an urgent challenge. An analysis annual total and maximum one-day precipitation from 1955 to 2023 performed with ERA5-Land dataset over EURO-CORDEX domain reveals emerging contrasting trends along much northern coast, heavy events increasing decreasing. independent investigation on a ground-based dense monitoring network southern Italy confirms results. We focus this representative...

Abstract In a general framework characterized by ever-increasing evidence of impacts attributable to climate change, the quantitative estimation wildfire emissions (e.g., black carbon, carbon monoxide, particulate matter) and evaluation its uncertainty are crucial for mitigation adaptation purposes. Global atmospheric emission models use mainly remote sensing fire datasets, which affected significant uncertainties. To assess errors sensing-based inventories, we compared temporal spatial...

This work provides the first continuous measurements of carbonaceous aerosol at Global Atmosphere Watch (GAW) Monte Curcio regional station, within southern Mediterranean basin. We specifically analyzed elemental carbon (EC) and organic (OC) concentrations in particulate matter (PM) samples, collected from April to December during two years 2016 2017. The purpose study is understand behavior both PM species, their fine coarse size fraction, along with seasonal variability. Based on 18 months...

Wildfire occurrence and severity in the Mediterranean region during summer season is increasing, being favoured by climate change-induced conditions (i.e., drought, heatwaves). Moreover, additional natural sources frequently impact this region, particularly Saharan dust intrusions. This study focuses on combined effect of wildfires air quality central Basin (CMB) 2017, an exceptional year for forested burned areas southern Italy. The annual behaviors PM2.5, PM10, CO, benzene, benzo(a)pirene...

Abstract This study investigates the spatial and temporal dynamics of Dissolved Organic carbon (DOC) concentration in a Mediterranean headwater catchment (Turbolo River catchment, southern Italy) equipped with two multi‐parameter sondes providing more than two‐year (May 2019–November 2021) continuous high‐frequency measurements several DOC‐related parameters. The were installed nested sections, quasi‐pristine upstream sub‐catchment downstream outlet anthropogenic water quality disturbances....

Abstract. The Global Mercury Observation System (GMOS) project, has developed a global-scale network of ground-based atmospheric monitoring sites, expanding the coverage mercury (Hg) measurements worldwide and improving understanding global Hg transport deposition, particularly in regions South Hemisphere where observational data is limited. This work provides first continuous records gaseous elemental (GEM) concentrations observed from October 2012 to May 2016 Northwestern Patagonia...

The effects of a Summer Firework Festival on the air quality were studied for first time in rural area Southern Italy. case study analyzes physical-chemical properties airborne particles collected during Note di Fuoco (NDF) Festival, which took place Belvedere M.mo 2016. sampling period was peculiar since one week three different kinds events have succeeded: days NDF with concurrence festival and firework displays, day typical street Market involving food stalls specialty shops, no specific...

This study investigates the spatial and temporal dynamics of DOC concentration in a Mediterranean headwater catchment (Turbolo River catchment, southern Italy) equipped with two multi-parameter sondes providing more than two-year (May 2019 to November 2021) continuous high-frequency measurements several DOC-related parameters. The were installed nested sections, quasi-pristine upstream sub-catchment downstream outlet some anthropogenic disturbances on water quality. estimates achieved by...

Hydrological factors are known to contribute regulate the DOC balance at reach scale. Interannual, intra-annual (seasonal) and event-based hydrological variability, particularly in headwater streams, affects stream-hillslope organic matter exchanges river network connectivity, leading significant space time variations sources processes regulating dynamics.This paper contributes ongoing effort improve understanding of related dynamics streamflow concentration spatial variability across...

Table S1.Descriptive statistics of meteorological variables [temperature (t), wind speed (ws), direction (wd) and relative humidity (rh)] GEM concentration recorded at the EMMA Station (Nahuel Huapi National Park, Northwestern Patagonia) are reported referring to both whole data frame (October 23, 2012 -May 15, 2016), as well each four seasons (Summer, Autumn, Winter Spring) .

<p>While observations of Mediterranean SST (Sea Surface Temperature) are showing an increasing trend during the last decades, future CMIP6 (Coupled Model Intercomparison Project Phase 6) projections highlight a further increase approximately 3 °C, according to SSP3-7.0 (Shared Socioeconomic Pathway) scenario. Among coastal areas Basin, Calabrian peninsula (southern Italy) is particularly prone severe hydrometeorological events due intense atmosphere-sea...

<p class="western" align="justify">The climate change induced-events are affecting the Mediterranean Sea through ever-increasing frequent and severe heatwaves droughts, which primary drivers for wildfires diffusion. This study aims to comprehensively investigate wildfires' impact on emissions of PM2.5 Black Carbon during fire seasons in southern Italy.  As a first step, Lagrangian transport produced by impacting two National...

<p>In the Mediterranean region, climate change-induced effects (i.e., increasing drought and heatwaves) are intensifying wildfire occurrences severity. During 2017 administrative region of Calabria (southern Italy) was affected by an exceptional season. This study evaluates impact on some air quality parameters in two National Parks, located north south respectively. Two sampling stations were considered for assessment, namely Monte Curcio Global Atmosphere Watch (GAW) regional...
