Atmosferická alektrina a sekundárne kozmické žiarenie
Atmospheric electricity and secondary cosmic radiation
Program: Inter-academic agreement
Project leader: Mgr. Langer Ronald
Annotation: A continuation of recently started joint investigation into the relation between atmospheric electricity and dynamics, secondary cosmic radiation and space weather is proposed. A special focus will be paid to events that occur during thunderstorms, e.g., to enhanced count rates that were observed in particle detector SEVAN during periods of large electric fields, and search for a possible detection of particles during individual atmospheric discharges. The study will be based on measurements of electrostatic field, electromagnetic radiation from lightning, meteorological data, and energetic particles and gamma-rays on Lomnický peak. A further improvement and extension of measurement setup around Lomnický peak is anticipated. Atmospheric electric field will also be measured at several places in the Czech Republic. The main goal of the proposed project is a better understanding of mechanisms that couple atmospheric electricity and thunderstorms with energetic particles (radiation) and space weather. Both statistical approach and analysis of individual events will be performed.

Kozmické žiarenie pozorované na dvoch vysokohorských observatóriách: Moussala a Lomnický štít
Cosmic rays as observed at two high mountain observatories: BEO Moussala and Lomnicky Stit
Program: Inter-academic agreement
Project leader: Mgr. Langer Ronald
Annotation: The main idea of the project is bilateral cooperation between two European high mountain stations (Lomnický štít, Slovakia and BEO Moussala, Bulgaria) in the field of solar phenomena (or extreme space whether events) as Forbush decrease (FD) and modulation effects on galactic cosmic rays (GCR), and their possible correlation with meteorological parameters. A Forbush decrease is a rapid decrease in the observed galactic cosmic ray intensity following a coronal mass ejection (CME). It occurs due to the magnetic field of the plasma solar wind sweeping some of the GCR away from Earth. The FD is usually observable by particle detectors on Earth within a few dаys аfter the CME, аnd the decrease takes place over the course of a few hours. Over the following severаl dаys, the sоlar cоsmic ray intensity rеturns tо nоrmal.Peer reviewed article (2) from 2009 found that low clouds contain less liquid water following Forbush decreases, and for the most influential events the liquid water in the oceanic atmosphere can diminish by as much as 7%. Further work (3, 4) found no connection between Forbush decreases and cloud properties until the connection was found in diurnal temperature range (5) and since confirmed in satellite data (6).8NM64 neutron monitor measures continuously cosmic rays at Lomnický Štít (2634 m a.s.l., rigidity cut-off ~4GV) with high statistical accuracy (average count rate ~440 s-1) since December 1981 (7).The muon telescope at BEO Moussala (2925 m a.s.l., rigidity cut-off ~6.3 GV) is in operation since August 2006. The averaged yearly data show good anti-correlation with the averaged sun-spot number for the period August 2006 – June 2017 (to be published elsewhere), several FDs were also detected (8, 9 and 10). The CR data from the two stations will be analyzed for 11 years period and correlations between their variations and meteorological parameters will be investigated (11, 12). The effect of strong electric field around the time of the thunderstorms will be searched both at Moussala and at Lomnický štít with help of similar detector systems SEVAN being in operation at both stations as it was done recently for Lomnický štít (15). This may be especially importance because of different shape of surface at the stations (Lomnicky stit is rather sharp in altitude profile). The physics behind climate change is still a subject of discussion and in need of further analysis (13). The standard method of examining the effect of CR on CC is to search for a correlation of the time series of the two quantities: CC and CR (14). There are numbers of factors which need to be kept in mind, as follows: the presence of a correlation between CR and CC; the nature of CC; Global, spatial variability; Global temporal variability;Altitude differences. In what follows we examine the comprehensive meteorological data from the Lomnicky stit (LS) and BEO Moussala mountain observatories in comparison with Global data to answer the question: is there support for the hypothesis that CR contribute significantly to the local climate, by way of enhanced cloud cover?References1.
