Did Open Solar Magnetic Field Increase during the Last 100 Years: A Reanalysis of Geomagnetic Activity
K. Mursula, D. Martini, A. Karinen
Long-term geomagnetic activity presented by the aa index has been used to show that the heliospheric magnetic field has more than doubled during the last 100 years. However, seriou…

Latitudinal dependence of low cloud amount on cosmic ray induced ionization
I. G. Usoskin, N. Marsh, G. A. Kovaltsov +2
A significant correlation between the annual cosmic ray flux and the amount of low clouds has recently been found for the past 20 years. However, of the physical explanations sugge…
