SSN and FLUX refer to sun spot number and solar radio flux, respectively. North American GCR neutron data for Newark, New Jersey (NM1) and Thule Air Force base, Greenland (NM2). Climatological indices included in the correlation matrix are the Atlantic Multidecadal Oscillation (AMO), the Quasi-Biennial Oscillation (QBO), the multivariate El Nino Southern Oscillation (ENSO), the North Atlantic Oscillation (NAO), and the Pacific Decadal Oscillation (PDO). Bold coefficients indicate p-vales less than 0.05.
