Data & Maps

• Global background ozone levels are not well documented as few ozone measurements have been made in many parts of the world. In an effort to bridge this information gap, a global-scale ozone air monitoring network was designed based on the use of ozone passive air monitoring devices. Volunteers at more than 400 locations around the world assisted us with this two part study in March and August, 1999. http://www.thesalmons.org/ozone/data.html
