Abstract. In a companion paper (Horváth et al., 2021), we introduced new technique to estimate volcanic eruption column height from extremely oblique near-limb geostationary views. The current demonstrates and validates the in number of recent eruptions, ranging ones with weak columnar plumes subplinian events massive umbrella clouds overshooting tops that penetrate stratosphere. Due its purely geometric nature, method is shown be unaffected by limitations traditional brightness temperature...
Abstract The Kuril Island arc extending for about 1,200 km from Kamchatka Peninsula to Hokkaido is a typical active subduction zone with ∼40 historically subaerial volcanoes, some of which are persistently degassing. Seven Kurilian volcanoes (Ebeko, Sinarka, Kuntomintar, Chirinkotan, Pallas, Berg, and Kudryavy) on six islands (Paramushir, Shiashkotan, Ketoy, Urup, Iturup) emit into the atmosphere > 90% total fumarolic gas arc. During field campaigns in 2015–2017 direct sampling fumaroles,...
Abstract. A geometric technique is introduced to estimate the height of volcanic eruption columns using generally discarded near-limb portion geostationary imagery. Such oblique observations facilitate a height-by-angle estimation method by offering close-to-orthogonal side views protruding from Earth ellipsoid. Coverage restricted daytime point estimates in immediate vicinity vent, which nevertheless can provide complementary constraints on source conditions for modeling near-field plume...

Noctilucent, or "night-shining," clouds (NLCs) are a spectacular optical nighttime phenomenon that is very often neglected in the context of atmospheric optics. This paper gives brief overview current understanding NLCs by providing simple physical picture their formation, relevant observational characteristics, and scientific challenges NLC research. Modern ground-based photographic observations, carried out framework automated digital camera networks around globe, outlined. In particular,...
Abstract We report on the first common volume ground‐based and space measurements of mesospheric front in noctilucent clouds (NLCs). The detailed observations were performed with automated digital cameras located at Athabasca University Geophysical Observatory (Canada) night 29–30 June 2012, while simultaneous conducted onboard Thermosphere Ionosphere Mesosphere Energetics Dynamics satellite using Sounding Atmosphere Broadband Emission Radiometry instrument. large temperature difference...
Abstract On 27 November 2012 at 1715 local time, a focused swarm of earthquakes was interpreted as the start new ongoing eruption on south flank (Tolbachinsky Dol) Plosky Tolbachik volcano in east central Kamchatka, Russia (Figure 1a) [Samoylenko et al., 2012]. Visual observations 29 showed ash shooting from two fractures well long, rapidly moving lava flows. Although initial clouds reached 6 kilometers height, subsequent ashfall has been limited to area around main vents, and no permanent...

AbstractThe present research examines the measured morphometric values of monogenetic cinder cones in Tolbachik volcanic field, Kluchevskaya group, Kamchatka. The were from digital elevation models (DEMs) derived satellite data (ASTER, ALOS PALSAR, and SRTM) digitized topographic maps. GPS measurements 85 locations performed field to provide geodetic reference for DEM processing assess accuracy DEM. A methodology on a is proposed. parameters include main characteristics that control rate...
