Abstract. We report attempted validation of Ozone Monitoring Instrument (OMI) sulfur dioxide (SO2) retrievals in the stratospheric volcanic cloud from Sarychev Peak (Kurile Islands) in June 2009, through opportunistic deployment of a ground-based ultraviolet (UV) spectrometer (FLYSPEC) as the volcanic cloud drifted over central Alaska. The volcanic cloud altitude (~12–14 km) was constrained using coincident CALIPSO lidar observations. By invoking some assumptions about the spatial distribution of SO2, we derive averages of FLYSPEC vertical SO2 columns for comparison with OMI SO2 measurements. Despite limited data, we find minimum OMI-FLYSPEC differences within measurement uncertainties, which support the validity of the operational OMI SO2 algorithm. However, our analysis also highlights the challenges involved in comparing datasets representing markedly different spatial and temporal scales. This effort represents the first attempt to validate SO2 in a stratospheric volcanic cloud using a mobile ground-based instrument, and demonstrates the need for a network of rapidly deployable instruments for validation of space-based volcanic SO2 measurements.

By invoking some assumptions about the spatial distribution of SO2, we derive averages of FLYSPEC vertical SO2 columns for comparison with OMI SO2 measurements. Despite limited data, we find minimum OMI-FLYSPEC differences of ~5–6 % which support the validity of the operational OMI SO2 algorithm. These measurements represent the first attempt to validate SO2 in a stratospheric volcanic cloud using a mobile ground-based instrument, and demonstrate the need for a network of rapidly deployable instruments for validation of space-based volcanic SO2 measurements.

A New Species

The world’s most northern species of the nudibranch genus Adalaria rossica sp. nov. from Franz Josef Land and a new species of Onchidoris expectata sp. nov. from the north-west Pacific Matua Island (Kurile Islands) are described. Prior to this study the nudibranch fauna from Franz Josef Land was represented only by two common North Atlantic species. Molecular taxonomic data were not applied for the Franz Josef Land nudibranchs previously. Nudibranchs of Matua Island have never been investigated. Furthermore, a new North Pacific taxon, Adalaria ultima sp. nov., is described here. The taxonomy of the onchidoridid genera Adalaria and Onchidoris is discussed.
