Black carbon (BC) and brown carbon (BrC) are light‐absorbing aerosols with significant climate impacts, but their absorption properties and direct radiative effect (DRE) remain uncertain. We simulated BC and BrC absorption during the intense Canadian boreal wildfires in June 2023 using an enhanced version of CHIMERE chemical and transport model. Th...

The uncertainty of hydrological forecasts is strongly related to the uncertainty of the rainfall field due to the nonlinear relationship between the spatio-temporal pattern of rainfall and runoff. Rain gauges are typically considered to provide reference data to rebuild precipitation fields. However, due to the density and the distribution variabil...

Italy is a territory characterized by complex topography with the Apennines mountain range crossing the entire peninsula and its highest peaks in central Italy. Using the latter as our area of interest and the snow seasons 2018/19, 2019/20 and 2020/21, the goal of this study is to investigate the ability of a simple single-layer and a more sophisti...

Central Italy is characterized by complex orography. The territorial response to heavy precipitation may activate different processes in terms of hydrogeological hazards. Floods, flash floods, and wet mass movements are the main ground effects triggered by heavy or persistent rainfall. The main aim of this work is to present a unique tool that is b...

Abstract The increase of human settlements and activities in coastal areas is causing a significant impact on coastal water quality. Predicting and monitoring the latter is of fundamental importance for assessing sustainable coastal engineering and ecosystem health. This trend is strongly influenced by the presence of rivers’ mouths, acting as crit...

Many of the estuaries and coastal areas in Europe are used for the cultivation and harvesting of bivalve mollusks. Mussel farming is strongly influenced by weather and environmental conditions. Several studies have shown that the sanitary conditions of shellfish are related to hydrological factors of rivers adjacent to the farming area, as rivers a...

Italy is a territory characterized by complex topography with the Apennines mountain range crossing the entire peninsula with its highest peaks in central Italy. Using the latter as area of interest and the winter season during 2018–2019, the goal of this study is to investigate the ability of snow cover models to reproduce the observed snow height...

Biological early warning systems (BEWS) are installed worldwide for the continuous control of water intended for multiple uses. Sentinel aquatic organisms can alert us to contaminant presence through their physiological or behavioural alterations. The present study is aimed at sharing the experience acquired with water biomonitoring of the Gran Sas...

Black carbon (BC), brown carbon (BrC), and soil dust are the most important radiation-absorbing aerosols (RAAs). When RAAs are deposited on the snowpack, they lower the snow albedo, causing an increase in the solar radiation absorption. The climatic impact associated with the snow darkening induced by RAAs is highly uncertain. The Intergovernmental...

Emerging contaminants could exert combined toxic effects, including synergetic and antagonistic ones, that cannot be identified by chemical analysis tools. The biological early warning systems (BEWS) perform a real-time and continuous (24 h) monitoring of physiological and/or behavioural parameters of organism alterations, potentially correlated to...

The southern peninsula in India mostly welcomes rainfall period during the northeastern monsoon in the months of November and December. Chennai, a city in the Indian state of Tamil Nadu in the southern India, received an extreme amount of rainfall on 1 December 2015 recording over 400mm within 24hr. This was causes by the unusual wind surges in the...

Floods and flash floods are complex events, depending on weather dynamics, basin physiographical characteristics, land use cover and water management. For this reason, the prediction of such events usually deals with very accurate model tuning and validation, which is usually site-specific and based on climatological data, such as discharge time se...

Highly populated coastal environments receive large quantities of treated and untreated wastewater from human and industrial sources. Bivalve molluscs accumulate and retain contaminants, and their analysis provides evidence of past contamination. Rivers and precipitation are major routes of bacteriological pollution from surface or sub-surface runo...

Black carbon (BC), brown carbon (BrC) and soil dust are the most radiation absorbing aerosols (RAA). When RAA are deposited on the snowpack, they lower the snow albedo, increasing the absorption of the solar radiation. The climatic impact associated to snow darkening induced by RAA is highly uncertain. In this work, a 5-years simulation with GEOS-C...

The weather forecasts for precipitation have considerably improved in recent years thanks to the increase of computational power. This allows for the use of both a higher spatial resolution and the parameterization schemes specifically developed for representing sub-grid scale physical processes at high resolution. However, precipitation estimation...

Hydrological forecasting is becoming increasingly important in the context of climate change impact assessment on people safety, economy, ecosystems and social sciences. Extreme weather events connected with water availability are becoming more frequent and predictions of hydrological phenomena deals with civil protection activities, as well as wat...

The response of Mediterranean small catchments hydrology to climate change is still relatively unexplored. Regional Climate Models (RCMs) are an established tool for evaluating the expected climate change impact on hydrology. Due to the relatively low resolution and systematic errors, RCM outputs are routinely and statistically post-processed befor...

Air presence of particulate pollutants is an environmental problem with significant health issues. Monitoring their concentration is a key factor for the correct management of urban activities. In the smart cities scenario, the most fruitful tools for such application are sensor networks combined with machine learning techniques. In this work, neur...

A new concept of Decision Support System (DSS) is presented. It is able to account for and support all phases of the risk analysis process: event forecast, prediction of reliable and accurate damage scenarios, estimate of their impact on Critical Infrastructures (CI), estimate of the possible consequences. It also provides an estimate of the conseq...

In 2012, six years after the previous epidemic, Bluetongue virus serotype 1 (BTV-1) re-emerged in Sardinia causing a limited number of outbreaks. Due to impossibility of implementing a vaccination campaign, the BTV-1 then spread all over the island in 2013 with about 7,000 outbreaks and, in September 2013, the virus reached Central Italy, with a li...
