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 nearby Canary Islands covering mean area 120 ± 202 km2 whole period sulphur dioxide reached Remote three mainly composed sulphates, which transported into free troposphere. high backscatter-related Ångström exponents for wavelengths 532–1064 nm (1.17 0.20 to 1.40 0.24) low particle depolarization ratios (0.08 0.02 0.09 0.02), measured multi-wavelength Raman lidar, hinted presence spherical small particles. layer aerosol optical depth 532 (AODL532) obtained measurements contributed between 49% 82% AERONET total column AOD in event II (11–13 October). According retrievals, 440 (AODL440) was higher all values 0.097 (Badajoz) 0.233 (Guadiana-UGR) lower III (19–21 October) varying 0.003 (Granada) 0.026 (Évora). Compared retrievals nm, AODL440 had contributions 21% 52% II. In I (25–28 September), volume concentrations (VC) varied 5 4 μm3cm−3 (El-Arenosillo/Huelva) 17 10 (Guadiana-UGR), while this variation 11 7 27 (Guadiana-UGR). Due impact on atmospheric economic fields, radiative forcing airspace security, proper characterization required. This work undertakes it using advanced instrumentation methods.
