Abstract. We present a multi-sensor archive collecting spatial and temporal information about volcanic SO2 clouds generated by the 11 largest eruptions of this century. The detection monitoring are an important topic for aviation management, climate issues weather forecasts. Several studies focusing on single eruptive events exist, but no available at moment combines quantitative data from as many instruments. archived collocated vertical column density estimations three different satellite instruments (AIRS, IASI GOME-2), atmospheric parameters profiles Global Navigation Satellite Systems (GNSS) Radio Occultations (RO), cloud-top height aerosol type Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP). Additionally, we provide algorithms anomaly due to presence cloud. dataset is gathering 206 d data, 44 180 backscatter 64 764 radio occultation profiles. modular structure allows easy collocation datasets according users' needs, cross-comparison shows consistency estimated sensors algorithms, sensitivity resolution described here published DOI https://doi.org/10.5880/fidgeo.2020.016 (Tournigand et al., 2020a).
