Characterization of Tajogaite volcanic plumes detected over the Iberian Peninsu...
Salgueiro, Vanda; Guerrero-Rascado, Juan Luis; Costa, Maria João; Román, Roberto; Cazorla, Alberto; Serrano, Antonio; Molero, Francisco; Sicard, MichaelThree volcanic plumes were detected during the Tajogaite volcano eruptive activity (Canary Islands, Spain, September–December 2021) over the Iberian Peninsula. The spatiotemporal evolution of these events is characterised by combining passive satellite remote sensing and ground-based lidar and sun-photometer systems. The inversion algorithm GRASP is used with a suite of ground-based remote sensing instruments s...
Vertical characterization of fine and coarse dust particles during an intense S...
López-Cayuela, Maria Ángeles; Córdoba-Jabonero, Carmen; Bermejo-Pantaleón, D.; Sicard, Michael; Salgueiro, Vanda; Molero, FranciscoAn intense and long-lasting Saharan dust outbreak crossed the Iberian Peninsula (IP) from the southwest (SW) to the northeast (NE) from 25 March until 7 April 2021. This work aims to assess the optical and mass contribution of both fine and coarse dust particles along their transport. Five Iberian lidar stations were monitoring the transport and evolution of the Saharan dust particles, i.e. El Arenosillo/Huelva...
Statistical Intercomparison of Aeolus B10 SCA and SCAmb Backscatter Coefficient...
Abril-Gago, Jesus; Guerrero-Rascado, Juan Luis; Costa, Maria João; Bravo-Aranda, Juan Antonio; Sicard, Michael; Bermejo-Pantaleón, DiegoIn this work, we perform an intercomparison of Aeolus reprocessed B10 (baseline 10) SCA (Standard Correct Algorithm) and SCAmb (Standard Correct Algorithm middle bin) co-polar backscatter coefficients ( ) with analogous ground-based measurements from the ACTRIS/EARLINET stations of Granada (Spain, 24 matching overpasses), Évora (Portugal, 15 overpasses) and Barcelona (Spain, 16 overpasses). Ground-based total p...
Intense Saharan Dust Outbreak over the Iberian Peninsula in springtime 2021: Mo...
López-Cayuela, M. A.; C. Córdoba-Jabonero, C.; Bermejo-Pantaleón, D.; Sicard, Michael; Salgueiro, Vanda; Molero, F.; Granados-Muñoz, M. J.In spring 2021 an intense Saharan dust outbreak reached the Iberian Peninsula (IP), lasting from 26 March until 5 April. It was monitored at six lidar stations, belonging to either MPLNET or ACTRIS/EARLINET networks, covering thus almost all the IP extension. Polarized Micro-Pulse Lidar measurements were carried out at El Arenosillo/Huelva (ARN, Spain; 37.1ºN, 6.7ºW, 40 m a.s.l.), Torrejón de Ardoz (TRJ, Spain;...
Statistical validation of Aeolus L2A particle backscatter coefficient retrieval...
Abril-Gago, Jesus; Guerrero-Rascado, Juan Luis; Costa, Maria João; Bravo-Aranda, Juan Antonio; Sicard, Michael; Bermejo-Pantaleón, DiegoThe Global Observing System (GOS) has encountered some limitations due to a lack of worldwide real-time wind measurements. In this context, the European Space Agency (ESA) has developed the Aeolus satellite mission, based on the ALADIN (Atmospheric Laser Doppler Instrument) Doppler wind lidar; this mission aims to obtain near-real-time wind retrievals at the global scale. As spin-off products, the instrument re...
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...
EARLINET evaluation of the CATS Level 2 aerosol backscatter coefficient product
Proestakis, Emmanouil; Amiridis, Vassilis; Marinou, Eleni; Binietoglou, Ioannis; Ansmann, Albert; Wandinger, Ulla; Hofer, Julian; Yorks, JohnWe present the evaluation activity of the European Aerosol Research Lidar Network (EARLINET) for the quantitative assessment of the Level 2 aerosol backscatter coefficient product derived by the Cloud-Aerosol Transport System (CATS) aboard the International Space Station (ISS; Rodier et al., 2015). The study employs correlative CATS and EARLINET backscatter measurements within a 50 km distance between the groun...
EARLINET VALIDATION OF CATS L2 PRODUCT
Proestakis, Emmanouil; Amiridis, Vassilis; Kottas, Michael; Marinou, Eleni; Binietoglou, Ioannis; Ansmann, Albert; Wandinger, Ulla; Yorks, JohnThe Cloud-Aerosol Transport System (CATS) onboard the International Space Station (ISS), is a lidar system providing vertically resolved aerosol and cloud profiles since February 2015. In this study, the CATS aerosol product is validated against the aerosol profiles provided by the European Aerosol Research Lidar Network (EARLINET). This validation activity is based on collocated CATS-EARLINET measurements and ...
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 ...
