Ice-core evidence for a small solar-source of atmospheric nitrate
A precision-dated ice-core nitrate record from Law Dome, coastal East Antarctica is compared to the timing of known solar proton events and geomagnetic storms over the period 1888 to 1995. We find statistical evidence for a significant (P < 0.03) but small elevation in mean nitrate concentrations...
