Abstract
The quasi-five-year variation in the abundance of nitrate in Central Greenl and ice is revealed. Probable origin of the variation is the connection of solar proton events with the period of declining solar activity. Such a con nection exists during more than 200 years and appears to be a fundamental p roperty of solar activity.
