Summary authors & editors: Joan Aron; Martin Ruzek
This map shows the average pH of rainfall measured during the year 2000 by the US National Atmospheric Deposition Program which operates an acid rain observing network. Lower pH values indicate increased acidity. "Ecosystem Change and Public Health - A Global Perspective" , a new book discussing a range of environmental issues, uses this series of acid rain maps and other information in explaining the chemistry and the impact of acid rain as part of an Earth systems approach to global change studies. The NASA Earth Science Enterprise 2001 education products review has recognized this text as an outstanding educational product.
