Two sets of nitrate (NO3−) concentration data in Central Greenland ice, obtained through the GISP2 collaboration and by the University of Kansas, were analyzed statistically. The two records correlate well over time scales from a few years up to a

A series of yearly data on the concentration of radioactive carbon 14C in tree rings measured at the Tbilisi State University in 1983–1986 and covering the time interval 1600–1940 is statistically analyzed. We find evidence for a 22-year cyclicit

Bidecadal fluctuations in terrestrial climate were analyzed. It was shown that this variability might arise if Earth's climate reacts to galactic cosmic-ray intensity, integrated over its full quasi-11-year cycle. It was further shown that this integ

Long-term changes of the GCR intensity in the heliosphere were analysed making use of records of cosmogenic isotopes abundances (10Be and 14C) in natural archives and neutron monitor data. These data contain information about short-term, 11-year, 22-

In the present paper we study variations of the nitrate content in Greenland ice core for the last 400 years. These data were obtained by high-precision measurements performed by the University of Kansas. It is shown that approximately 20-year period

Past solar activity is studied based on analysis of data on the nitrate content of Greenland ice in the period from 1576–1991. Hundred-year (over the entire period) and quasi-five-year (in the middle of the 18th century) variations in the nitrate c

We discuss the energy release process in a solar flare. The onset of this flare in soft X-rays was detected at 00:18 UT on April 22nd, 1994, by the IRIS X-ray spectrometer, which was a component of the scientific payload in the international complex
