Understanding Atmospheric Neutralization and it's Dependence
An Introduction to Acidity Trends across the United States of America.
Trends in Atmospheric Neutralization
Strong Acidity and Neutralization based on seasonal trends and the inclusion of Na+ and Cl-.
Rate of Change
Estimation of changes in the strong acidity and neutralization within 2004-2010 by linear regression and the Theil-sen slope method. Abbreviation for site names are GLA: Glacier NP, GRA: Grand Canyon NP, PER: Perkinstown, SHE: Shenandoah NP, PEN: Penn State, GEO: Georgia Station. 1) Strong acidity is given as a percentage of increase and decrease from average over a year. 2) Neutralization is given as a unit increase or decrease within a year. 3) Calculation without Na+ and Cl- was within the time range of 2004-2010 for consistency.
