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. This paper introduces the recent European Aerosol Research Lidar Network (EARLINET) quality-assurance efforts at instrument level. Within two dedicated campaigns and five single-site intercomparison activities, 21 EARLINET systems from 18 stations were intercompared between 2009 2013. A comprehensive strategy for campaign setup data evaluation has been established. Eleven nine participated in Intercomparison (EARLI09). In this campaign, three reference qualified which served as...
Abstract Western Patagonia (40–56°S) is a clear example of how the systematic lack publicly available data and poor quality control protocols have hindered further hydrometeorological studies. To address these limitations, we present PatagoniaMet (PMET), compilation ground-based (PMET-obs; 1950–2020), daily gridded product precipitation temperature (PMET-sim; 1980–2020). PMET-obs was developed considering 4-step process applied to 523 time series obtained from eight institutions in Chile...
Abstract. In the framework of ACTRIS (Aerosols, Clouds, and Trace Gases Research Infrastructure Network) summer 2012 measurement campaign (8 June–17 July 2012), EARLINET organized performed a controlled exercise feasibility to demonstrate its potential perform operational, coordinated measurements deliver products in near-real time. Eleven lidar stations participated which started on 9 at 06:00 UT ended 72 h later 12 UT. For first time, single calculus chain (SCC) – common developed within...
This study evaluates the reliability of Weather Research and Forecasting (WRF) model to simulate extreme snowfall events in Southern Andes. The assessment includes comparison seven microphysics parameterizations (MPs) schemes, using two different reanalysis datasets as boundary initial conditions, namely NCEP-FNL ERA-interim. Results demonstrate feasibility predicting snow with reasonable accuracy WRF, but level is dependent on imposed conditions. In particular, by computing RMSE turned out...
This study evaluates the capabilities of Weather Research and Forecasting (WRF) model to reproduce variability precipitation over Central Andes Chile Argentina, a region characterized by complex topography. The simulation corresponds dynamical downscaling ERA-Interim, in period 1996–2015, performed with two nested grids, at 9 3 km horizontal resolution. Precipitation data from 62 rain gauges Argentina were used evaluate performance WRF simulations carried out annual warm-cold season...
The Concepción Metropolitan Area (CMA) in South-Central Chile presents a complex interplay of climatic conditions, tectonic activity, and varied topography that heightens landslide susceptibility. CMA is characterized by steep escarpments sloping valleys atop blocks. This setting creates landslide-prone areas as urban development extends into unstable hillslopes. Unfortunately, current inventories are limited inconsistent, hindering effective susceptibility zoning planning efforts. objective...
In the Southern Volcanic Zone of Andes (~33°S - ~46°S), glaciers occur only on highest peaks active volcanoes. Many these glaciers, hence, are located within craters or calderas that have a bowl-shaped basal geometry atypical to other mountain glaciers. Volcán Sollipulli, at about 39° S, hosts massive glacier fills caldera (diameter ~4 km), with relatively flat surface elevation ~2060 m in 2023/2024. Ground-penetrating radar data from 2013 suggested...
Mountain systems are experiencing significant impacts from changes in precipitation and temperature, directly affecting natural water reservoirs like glaciers snow. Projections suggest that some ranges may vanish entirely by the end of this century. Currently, loss glacier mass is already altering streamflow impacting dependent ecosystems. Snow cover has decreased globally, especially at lower elevations, due to more falling as rain rather than This dramatically changed hydrology mountain...
The present study introduces a methodology based on Socio-Hydrological Models Integrated with Agent-Based (SHABM) to identify and analyze potential water conflicts in the Longaví River Basin, Chile. This approach combines fieldwork characterize user profiles, computational modeling, simulations explore interactions among users, governance systems, hydrological dynamics context of limited resources.The Basin is defined by Mediterranean climate pluvial-nival regime that creates marked...
Stretching from ~33ºS to ~46ºS, the Southern Volcanic Zone (SVZ) in Andes constitutes one most continuous glaciated volcanic regions along midlatitudes. Here, headwaters are on active volcanoes, with glaciers a notable variety of forms, including valley glaciers, ice aprons, mountain and crater glaciers. Furthermore, ubiquitous glacial landforms attest for larger coverage past. Building earlier foundational case studies, since 2015 we have developed multidisciplinary...
Glaciers are of paramount importance in diverse environments, and due to the accelerated retreat experienced recent decades, efforts have intensified achieve a comprehensive understanding key variables such as mass balance glacial melting. However, scarcity data regions that difficult access, Andes Cordillera, hinders reliable glaciological studies historical period. This study examined melting dynamics Universidad Glacier, largest semi-arid Andes, from 1955 2020, using physically based Cold...
Abstract This study describes the performance of five gridded data sets in reproducing precipitation and/or temperature over complex terrain high Chilean Andes. The relationship instrumental observations and with climate modes variability trends indices extremes are also explored between period 1980–2015. mismatches larger northern southern regions relation to precipitation, while for temperature, disagreement is higher central region. However, better results delivered by Climatic Research...
