A long Saharan dust event over the western Mediterrranean: Lidar, Sun photometer observations and regional dust modeling
(2006-08-31)
Article
Accés obertA long Saharan dust event affected the western Mediterranean in the period 12– 28 June 2002. Dust was present mainly between 1- and 5-km height affecting most parts of the Iberian Peninsula and reaching western/central ... -
Application of a synergetic lidar and sunphotometer algorithm for the characterization of a dust event over Athens, Greece
(2013-11-18)
Article
Accés obertWe present first retrievals of the Lidar-Radiometer Inversion Code (LIRIC), applied on combined lidar and sunphotometer data during a Saharan dust episode over Athens, Greece, on July 20, 2011. A full lidar dataset in terms ... -
Estimation of mineral dust long-wave radiative forcing: sensitivity study to particle properties and application to real cases in the region of Barcelona
(2014-01-01)
Article
Accés obertThe aerosol radiative effect in the long-wave (LW) spectral range is sometimes not taken into account in atmospheric aerosol forcing studies at local scale because the LW aerosol effect is assumed to be negligible. At ... -
Forecasting the northern African dust outbreak towards Europe in April 2011: a model intercomparison
(2016-04-21)
Article
Accés obertIn the framework of theWorld Meteorological Organisation’s Sand and Dust Storm Warning Advisory and Assessment System, we evaluated the predictions of five state-of-the-art dust forecast models during an intense ... -
Profiling of Saharan dust from the Caribbean to western Africa – Part 2: Shipborne lidar measurements versus forecasts
(European Geosciences Union (EGU), 2017-12-12)
Article
Accés obertA unique 4-week ship cruise from Guadeloupe to Cabo Verde in April–May 2013 see part 1, Rittmeister et al. (2017) is used for an in-depth comparison of dust profiles observed with a polarization/Raman lidar aboard the ... -
Saharan dust events in the dust belt -Canary Islands- and the observed association with in-hospital mortality of patients with heart failure
(MDPI, 2020-01-30)
Article
Accés obertRecent studies have found increases in the cardiovascular mortality rates during poor air quality events due to outbreaks of desert dust. In Tenerife, we collected (2014–2017) data in 829 patients admitted with a heart ... -
Sources and processes affecting levels and composition of atmospheric particulate matter in the Western Mediterranean
(Universitat Politècnica de Catalunya, 2002-12-03)
Tesi
Accés obertThis study is focused on the identification of the sources and processes affecting levels and composition of PM10 and PM2.5 from air quality monitoring networks in Eastern Spain. This is a multidisciplinary study. Time ... -
Spatiotemporal evolution of a severe winter dust event in the western Mediterranean: Aerosol optical and physical properties
(2017-05-16)
Article
Accés obertAn outstanding Saharan dust event affected the Iberian Peninsula during winter 2016 (20 to 25 February). The impact of this event on ambient PM10 surface levels and its spatial and temporal evolution was investigated by ... -
The pulsating nature of large-scale Saharan dust transport as a result of interplays between mid-latitude Rossby waves and the North African Dipole Intensity
(Elsevier, 2017-10)
Article
Accés obertIt was previously shown that during August the export of Saharan dust to the Atlantic was strongly affected by the difference of the 700-hPa geopotential height anomaly between the subtropics and the tropics over North ...
