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...
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...
Abstract. Mineral dust has a key role in the Earth's radiative balance, and it become significant over Iberian Peninsula (IP), where Saharan outbreaks have seemed to increase frequency intensity. This study quantifies direct effect (DRE) short-wave range (SW) during an intense persistent springtime episode IP. In particular, vertical distribution of optical properties was derived at five lidar stations, Global Atmospheric Model (GAME) used for transfer simulations. Moreover, this innovates...
The volcanic eruption of Cumbre Vieja (La Palma Island, Spain), started on 19 September 2021 and was declared terminated 25 December 2021. A complete set aerosol measurements were deployed around the volcano within first month eruptive activity. This paper describes results observations made at Tazacorte west bank island where a polarized micro-pulse lidar deployed. analyzed two-and-a-half months (16 October–31 December) reveal that peak height lowermost strongest plume did not exceed 3 km...
Abstract. The short-wave (SW) direct radiative effect (DRE) during the summer 2019 heatwave produced partly by a moderate, long-lasting Saharan dust outbreak over Europe is analysed in this study. Two European sites (periods) are considered: Barcelona, Spain (23–30 June), and Leipzig, Germany (29 30 1350 km apart from each other. Major data obtained AERONET polarised Micro-Pulse Lidar (P-MPL) observations. Modelling used to describe different pathways, as observed at both sites. coarse (Dc)...
Abstract. Simultaneous observations of a polarized micro-pulse lidar (P-MPL) system and two reference European Aerosol Research Lidar Network lidars running at the Leipzig site Germany, 51.4∘ N, 12.4∘ E; 125 m a.s.l.) were performed during comprehensive 2-month field intercomparison campaign in summer 2019.

The aim of this study was to analyze the potential GRASP code retrieve optical and microphysical properties vertically-resolved using a synergy polarized Micro-Pulse Lidar Sun/sky photometer observations. focus on long-range transport Canadian aged-smoke plumes observed at El Arenosillo/Huelva (Spain) from 7 8 September 2017. Both columnar height-resolved were assessed in comparison with AERONET data vertical lidar-retrieved profiles, respectively. In particular, also derived POLIPHON...
In view of the existing controversy around origin photosynthesis and, therefore, first photosynthetic pigments, our work focuses on theoretical study a hypothetical pigment, simpler than those today, that collects energy from solar radiation Earth-like exoplanets. Our results show there could exist geochemical conditions allow abiotic formation primeval pigment might become sufficiently abundant in early stages habitable rocky These would place this before appearance life very young planet,...
Only a low percentage of the radiation from our Sun is captured by photosynthesis, but this conversion solar to chemical energy sustains all life on Earth. Photosynthesis could be present in any exoplanetary system fulfilling main three ingredients for metabolic route: light, water, and carbon dioxide. To deepen into idea, ExoPhot project aims study relation between photosynthetic systems exoplanet conditions around different types stars focusing two aspects: (i) Assessing fitness variety...
Abstract. Mineral dust has a key role in the Earth’s radiative balance, and it become significant over Iberian Peninsula (IP), where Saharan outbreaks seem to increase frequency intensity. This study quantifies direct effect (DRE) short-wave range (SW), during an intense persistent springtime episode IP. A long-term analysis (14 days) was performed five lidar stations. The vertical distribution of optical properties derived, finding wide dynamic aerosol concentration that allowed suitable...
The atmospheric dust cycle on Mars plays a dominant role in the planetary radiative balance, photochemistry escape, and redistribution of materials surface. Although this has been extensively modelled characterized with both orbital situ observations, to date little is known about total mass that circulated, actual lifting settling rates, main sources sinks. Using global seasonal measurements opacity, data reduction methodology can describe annual scale 95% accuracy presented. method was...
