Observing and understanding the Southeast Asian aerosol system by remote sensing: An initial review and analysis for the Seven Southeast Asian Studies (7SEAS) program

► The complex relationships between Southeast Asia's geographic, meteorological and aerosol systems are reviewed. ► There are few aerosol measurements in Southeast Asia, and those that do exist suggest significant regional variability. ► Southeast Asia hosts one of the world's most challenging aerosol observing environments. ► Satellite derived products for clouds, precipitation, fire and aerosol diverge significantly in Southeast Asia. ► If used properly, satellite products can provide significant insight into the regional aerosol environment.
