WMO/GAW Aerosol Measurement Procedures, Guidelines and Recommendations

WMO has a history of organizing aerosol measurements, as reflected in its promotion of monitoring stations globally, and workshops particularly focused on aerosol optical depth (AOD) such as those in 1986 (WMO/GAW Report No. 43) and 1994 (WMO/GAW Report No. 101). This report expands the guidelines on aerosol measurements from AOD 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.
