With the increasing demand for alternative energy sources, natural hydrogen is gaining attention commercial exploitation. Naturally accumulated only utilized today at field of Bourakébougou, Mali, highlighting major knowledge gaps in behaviour systems and related exploration-production workflows. Circular depressions called “fairy circles” represent a surface manifestation seeps that commonly occur continental cratons are formed relatively quickly (few years)....
Abstract. Rock salt has remarkable mechanical properties and high economic importance; however, the strength of compared to other rocks makes it a rather vulnerable material. Human activities could lead acceleration dissolution soluble rock collapse subsurface caverns. Although sinkhole development can be considered local geological disaster regarding characteristic size surface depressions, deformations result in catastrophic events. In this study we report spatiotemporal evolution...
During the peak days of 2019 Leonids and Geminids (16–19 November 10–16 December), two ionograms/minute one Skymap/minute campaign measurements were carried out at Sopron (47.63°N, 16.72°E) Průhonice (50.00°N, 14.60°E) Digisonde stations. The stations used frequencies between 1 17 MHz for ionograms, Skymaps made 2.5 MHz. A temporary optical camera was also installed with a lower brightness limit +1 visual magnitude. manual scaling ionograms December to study behavior regular sporadic E layer...
A Nemzeti Kutatási, Fejlesztési és Innovációs Hivatal által támogatott 2018-2.2.1-NKP-2018-00007 kutatási projekt végső célját Magyarország szeizmotektonikai modelljének megalkotása jelentette. megszületett új, országos modell „kézzelfogható”, a szakmai gyakorlatban közvetlenül is felhasználható megjelenítését két 1:500.000 léptékű térkép – veszélyeztetettségi térképe testesíti meg. Ezek az első ilyen típusú térképek országról. Hatékony segítséget nyújtanak különböző alapkutatási...
Mesoscale convective systems are effective sources of atmospheric disturbances that can reach ionospheric heights and significantly alter conditions. Convective affect the Earth’s atmosphere on a continental scale up to F-layer heights. Extratropical cyclone “Zyprian” occurred at beginning July, 2021 dominated weather over whole Europe. An extensive cold front associated with moved from western part eastern Europe, followed by ground-level convergence formation organized thunderstorm...
During the 2019 Leonid meteor shower, European Fireball Network recorded a bright fireball (meteor code: EN171119_041459) at 04:15:0.2 (UT) on 17 November 2019. The appeared coordinates 49.95°N 15.56°E height of 134.46 km, and disappeared 50.23°N 15.26°E 71.81 km. ionization effect caused by in digisonde’s campaign measurements taken with 2 ionogram/min time resolution Průhonice station (50.00°N, 14.60°E). trace ionograms as faint sporadic E-like layer, maximum reached upper limit...
The impact of individual meteors on the lower ionosphere (90-150 km height) has been investigated during wintertime meteor showers using measurements two DPS-4D Digisondes installed at Sopron (47.63°, 16.72°) and Pruhonice (50°, 14.5°). optical have performed by a zenith camera next to digisonde Sopron. It provided opportunity compare high cadence ionograms measured parallel with data determine plasma trails meteors. Campaign ionograms/minute station...

<p>In the last decades, development of space geodesy methods has allowed much more accurate observations planetary surface dynamics than before. The various SAR satellites, like global navigation systems, make their in different microwave frequency ranges (1-10 GHz). Earth's atmosphere is transparent to signal, but factors affecting wave propagation (propagation direction and velocity) medium are time-dependent, anisotropic, inhomogeneous and, case ionosphere, dispersive....
