Abstract

Erratum to: The spatial density gradient of galactic cosmic rays and its solar cycle variation observed with the Global Muon Detector Network

Highlights

Equation (4) in the original paper (Kozai et al 2014) was incorrect and needs to be multiplied by a factor 2, as ξzGEO

Summary

Introduction

Equation (4) in the original paper (Kozai et al 2014) was incorrect and needs to be multiplied by a factor 2, as ξzGEO. Masayoshi Kozai1*, Kazuoki Munakata1, Chihiro Kato1, Takao Kuwabara2, John W. A few sentences in the paper need to be reworded as follows.
