             abstract = "The north-south (NS) anisotropy, or NS asymmetry of galactic 
                         cosmic-ray (GCR) intensity, indicates a GCR flow perpendicular to 
                         the ecliptic plane which contains both the interplanetary magnetic 
                         field (IMF) and radial density gradient of GCRs induced by the 
                         solar modulation on average. This uniqueness of the pointing 
                         direction of NS anisotropy results in a phenomenon unseen in other 
                         anisotropy components, a reversal of its polarity according to the 
                         IMF sector polarity. The magnitude of the NS anisotropy reversal 
                         allows us to estimate the density gradient of GCRs, making it a 
                         unique indicator of the solar modulation of GCRs. Ground-based 
                         muon detectors are proven to provide more significant measurements 
                         of the NS anisotropy than neutron monitors, thanks to the small 
                         degradation of muon momentum directions in the atmospheric 
                         propagation and its relatively higher response rigidity to primary 
                         cosmic rays where the NS anisotropy is enhanced. However, the NS 
                         anisotropy measurements have suffered from the atmospheric 
                         temperature effect on muons. Recently a new correction method for 
                         the temperature effect using atmospheric re-analysis data was 
                         proposed. We are attempting a precise calculation of the NS 
                         anisotropy utilizing this correction method. Solar cycle 
                         variations of the NS anisotropy, or GCR density gradient, and its 
                         rigidity spectrum will be presented with unprecedented accuracy.",
