WMO/GAW Aerosol Measurement Procedures, Guidelines and Recommendations (2nd Edition)

This report expands the guidelines on aerosol measurements from Aerosol Optical Depth to include a comprehensive list of aerosol optical, physical and chemical measurements that are needed globally. It provides assistance to those involved in developing an integrated global aerosol measurement system for climate and atmospheric composition studies. It should be considered a living document that will be updated and revised according to new scientific and technological developments. The most recent update to this report can be found at http://www.wmo-gaw-wcc-aerosol-physics.org/wmo-gaw-reports.html.
