Fine and coarse dust radiative impact during an intense Saharan dust outbreak o...
López-Cayuela, M.A.; Córdoba-Jabonero, C.; Sicard, M.; Abril-Gago, J.; Salgueiro, Vanda; Comerón, A.; Granados-Muñoz, M.J.; Costa, Maria JoãoMineral dust has a key role in the Earth’s radiative balance, and it has become significant over the Iberian Peninsula (IP), where Saharan dust outbreaks have seemed to increase in frequency and intensity. This study quantifies the dust direct radiative effect (DRE) in the short-wave range (SW) during an intense persistent springtime dust episode over the IP. In particular, the vertical distribution of dust opt...
Extreme, wintertime Saharan dust intrusion in the Iberian Peninsula: Lidar moni...
Fernández, Alfonso; Sicard, Michael; Costa, Maria João; Guerrero-Rascado, J. L.; Gómez-Amo, J.L.; Molero, F.; Barragán, R.; Basart, S.; Bortoli, DanieleAn 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 extreme dust intrusion through passive and active remote sensing techniques. For that, AERONET (AErosol RObotic NETwork) and EARLINET (European Aerosol Research LIdar NETwork) databases are used. The sites considered ar...

Sicard, M.; Granados-Muñoz, M. J.; Alados-Arboledas, L.; Barragán, R.; Bedoya-Velásquez, A. E.; Benavent-Oltra, J. A.; Bortoli, Daniele; Comerón, A.During the 2017 record-breaking burning season in Canada/United States, intense wild fires raged during the first week of September in the Pacific northwestern region (British Columbia, Alberta, Washington, Oregon, Idaho, Montana and northern California) burning mostly temperate coniferous forests. The heavy loads of smoke particles emitted in the atmosphere reached the Iberian Peninsula (IP) a few days later o...
VERTICALLY-RESOLVED CHARACTERIZATION OF THE FEBRUARY 2016 EXCEPTIONAL SAHARAN D...
Guerrero Rascado, Juan Luis; Costa, Maria João; Sicard, Michael; Gómez-Amo, J. L.; Benavent-Oltra, J. A.; Román, R.; Bortoli, Daniele; Marcos, C.An unusual Saharan dust outbreak occurred on 20-24 February 2016 over the Iberian Peninsula. This work focuses on the particle vertical distribution investigated at four EARLINET AERONET stations: Granada, Évora, Burjassot and Barcelona. This event was exceptional because: (i) Saharan dust outbreaks over the Iberian Peninsula are atypical during wintertime,(ii) the aerosol optical depth reached high values (up ...
