Robustness of Solar-Cycle Empirical Rules Across Different Series Including an Updated ADF Sunspot Group Series
Ilya Usoskin, Gennady Kovaltsov, Wilma Kiviaho
Empirical rules of solar cycle evolution form important observational constraints for the solar dynamo theory. This includes the Waldmeier rule relating the magnitude of a solar cy…
A New Full 3-D Model of Cosmogenic Tritium H Production in the Atmosphere (CRAC:3H)
S. V. Poluianov, G. A. Kovaltsov, I. G. Usoskin
A new model of cosmogenic tritium (H) production in the atmosphere is presented. The model belongs to the CRAC (Cosmic-Ray Atmospheric Cascade) family and is named as CRAC:3H.…
Revisited reference solar proton event of 23-Feb-1956: Assessment of the cosmogenic-isotope method sensitivity to extreme solar events
Ilya G. Usoskin, Sergey A. Koldobskiy, Gennady A. Kovaltsov +4
Our direct knowledge of solar eruptive events is limited to several decades and does not include extreme events, which can only be studied by the indirect proxy method over millenn…
