Using the Solar Isotope Spectrometer (SIS) on NASA's ACE spacecraft, we have measured
the composition and energy spectra of anomalous cosmic rays (ACRs) near 1 AU down to
energies of ~10 MeV/nucleon since August 1997. Recently these measurements have been
augmented by data from the Low Energy Telescope (LET) on the STEREO spacecraft, which
allows us to extend the energy spectra down to ~3 MeV

We study the spatial gradients of galactic cosmic rays in the inner heliosphere using
data from the Kiel Electron Telescope (KET) aboard Ulysses and the Cosmic Ray Isotope
Spectrometer (CRIS) aboard the Advanced Composition Explorer (ACE) for the time
period from 1997 to 2007. This covers the solar minimum in the A>0-solar magnetic
epoch, the solar magnetic reversal to an A<0-magnetic epoch at

Be-7 is a familiar cosmogenic nuclide in the atmosphere. Since aerosols with
the Be-7 are fallen down from the upper troposphere to the ground, it is
possible to investigate the altitude distribution of the Be-7s from the size
distribution of aerosols attached by the Be-7s. Probably there are the aerosols
of small size in the upper altitude.
Therefore, using an Andersen air sampler, we s

In studying solar modulation of galactic cosmic rays, a modulation parameter \phi is
often used, whose value vary by a factor of more than 2 from the solar maximum to the
solar minimum, reflecting the effects of different levels of solar activities on the
modulation. Simple and elegant, this approach however, based on the assumption that
the current of GCRs is small and can be taken to be zero

A linear relationship between the observed 26-day recurrent cosmic-ray
intensity variations and the global latitudinal gradient was first reported by
Zhang (1997, ApJ, 488). Burger and Hitge (2004, ApJL, 617) used a three-
dimensional steady-state numerical modulation model and showed that a Fisk-
type (Fisk 1996, JGR, 101) heliospheric magnetic field (HMF) can in principle
explain these o
