Note that there are 35 air districts in California. Ten air districts that conduct ambient air quality monitoring are developing separate Annual Network Plans covering the ambient monitoring within their jurisdictions. This Annual Network Plan covers the 25 air districts for which the local air agencies are not drafting a separate report.
