An unprecedented extreme Saharan dust event was registered in winter time from 20 to 23 February 2017 over the Iberian Peninsula (IP). We report on aerosol optical properties observed under this intrusion through passive and active remote sensing techniques. For that, AERONET (AErosol RObotic NETwork) EARLINET (European Aerosol Research LIdar databases are used. The sites considered are: Barcelona (41.38°N, 2.17°E), Burjassot (39.51°N, 0.42°W), Cabo da Roca (38.78°N, 9.50°W), Évora (38.57°N,...
Abstract. An intense and long-lasting Saharan dust outbreak crossed the Iberian Peninsula (IP) from southwest (SW) to northeast (NE) 25 March until 7 April 2021. This work aims assess optical mass contribution of both fine coarse particles along their transport. Five lidar stations were monitoring transport evolution particles, i.e. El Arenosillo/Huelva, Granada, Torrejón/Madrid Barcelona in Spain, Évora Portugal. The particular meteorological conditions determined aerosol scenario overall...

A third site, Alborán (Alborán Spain), with only a few months data considered for...
Three volcanic plumes were detected during the Tajogaite volcano eruptive activity (Canary Islands, Spain, September–December 2021) over Iberian Peninsula. The spatiotemporal evolution of these events is characterised by combining passive satellite remote sensing and ground-based lidar sun-photometer systems. inversion algorithm GRASP used with a suite instruments such as lidar/ceilometer from eight sites at different locations throughout Satellite observations showed that ash remained...
The invasive alien, African giant snail, Lissachatina fulica, considered as a pest, poses significant threat to ecosystems, human health and agriculture across tropical subtropical regions. Therefore, in order address the challenge posed by presence of this animal outside its original habitat it is essential understand current potential future distribution. Thus, study, which highlights critical role regional bioclimatic datasets improving predictive accuracy species distribution models...
The laurel forest (laurisilva) represents a unique and biodiverse ecosystem currently confined to subtropical regions with specific climatic conditions. In the Canary Islands, these laurisilva forests, constrained areas high humidity stable temperatures as northern slopes of Tenerife, La Gomera, Palma, are particular ecological importance hosting numerous endemic species. However, climate change poses significant threat fragile habitats, potential shifts in their distribution at both...
Glyoxal (CHOCHO) is an intermediate product of the oxidation volatile organic compounds (VOCs) and has anthropogenic, biogenic pyrogenic sources. It indicator formation secondary aerosols in atmosphere plays a role photochemical reactions ozone troposphere. Additionally, at high concentrations glyoxal harmful for humans. The lifetime short (a few hours) it removed from by photolysis, OH, deposition. Due to different sources glyoxal, its abundance can vary between several parts per trillion...
In this paper, we illustrate a new, simple and complementary ground-based methodology to retrieve the vertically resolved atmospheric precipitation intensity through synergy between measurements from National Aeronautics Space Administration (NASA) Micropulse Lidar network (MPLNET), an analytical model solution disdrometer measurements. The presented results are obtained at two mid-latitude MPLNET permanent observational sites, located respectively NASA Goddard Flight Center, USA,...
A field campaign took place in the western and central Mediterranean basin on June–July 2013 framework of ChArMEx (Chemistry-Aerosol Experiment, http://charmex.lsce.ipsl.fr/)/ADRIMED (Aerosol Direct Radiative Impact regional climate MEDiterranean region, http://adrimed.sedoo.fr/) project to characterize aerosol direct radiative forcing (DRF) over Mediterranean. This work focuses DRF estimations at Lecce (40.33°N; 18.11°E; 30 m above sea level) during Saharan dust outbreak that affected...

Relative humidity (RH) profiling using Raman lidars requires simultaneous range-resolved temperature and pressure data that are not always available. We propose assess a method based on the use of locally retrieved atmospheric model to estimate profiles.
