Meteorological Effects

Continuous recording of the intensity of the hard component of cosmic rays has been carried out at Ottawa (Geomagnetic Lat. 56.8) and at Resolute (Geomagnetic Lat. 83) in the Canadian Arctic for over a year. Two counter telescopes with different amounts of lead shielding are used at each station. The results have been analyzed for barometer effect in four series of observations each extending over three months. When averaged, they show a barometer coefficient of –1.75% per cm. of mercury for mesons with momenta above 350 Mev./c and –2.13% per cm. of mercury for those with momenta above 630 Mev./c.A calculation has been made of the temperature and barometer effects. It was based on the variations in the probability of decay of mesons in the atmosphere, under varying atmospheric conditions. The calculations of the temperature effect do not yield results comparable with measurement; those of the barometer effect show that considerable information can be obtained about the meson spectrum from measurements of the barometer coefficients. The results favor a spectrum in agreement with parts of spectra measured by other authors. They suggest the possibility of a second maximum in the production spectrum of mesons.

Sidereal Anisotropy

The sidereal time variation is analyzed using data for the ion chambers at Cheltenham and Christchurch for the period 1938–58 and for the meson and neutron components during the IGY. All the results derived from these three kinds of data support the existence of a two-way sidereal anisotropy, suggested by Jacklyn, which has two maxima of the cosmic-ray intensity in the directions of 8 h and 20 h S.T. (sidereal time).

Ray Effects

Ionizing radiation sources such as Solar Energetic Particles and Galactic Cosmic Radiation may cause unexpected errors in imaging and communication systems of satellites in the Space environment, as reported in the previous literature. In this study, the temporal variation of the speckle values on Sentinel 1 satellite images were compared with the cosmic ray intensity/count data, to analyze the effects which may occur in the electromagnetic wave signals or electronic system. Sentinel 1 Synthetic Aperture Radar (SAR) images nearby to the cosmic ray stations and acquired between January 2015 and December 2019 were processed. The median values of the differences between speckle filtered and original image were calculated on Google Earth Engine Platform per month. The monthly median “noise” values were compared with the cosmic ray intensity/count data acquired from the stations. Eight selected stations’ data show that there are significant correlations between cosmic ray intensities and the speckle amounts. The Pearson correlation values vary between 0.62 and 0.78 for the relevant stations.

The results of the analysis of data obtained from measurements carried out by means of regular stratospheric launchings of cosmic-ray radiosondes over the Murmansk region and the Antarctic observatory in Mirny in 1963–66 are presented. The problem of the anisotropy of the primary component of low-energy cosmic rays and of temperature effects on the cosmic-ray intensity in the atmosphere are discussed.
