Paper Abstract

Understanding the effect of aerosol on clouds and cloud systems is one of the major challenges in climate research. Local studies suggest a multitude of aerosol influences on cloud properties, some increasing cloud albedo and some decreasing it. The net effect remains uncertain. NASA's TRIANA mission, which would see the whole sunlit face of the Earth continually, would provide simultaneous data on aerosol properties and cloud reflectivity from its EPIC multi-spectral imager. With TRIANA's unique position at the L-1 Lagrange point, these data would be available not only globally but also over the entire daytime, well suited to accommodate the often short lifetimes of aerosol and investigations around diurnal cycles. This pilot study explores the ability to detect relationships between aerosol properties and cloud-reflectivity with advanced statistical methods and applies to any L-1 imager with similar capabilities. Prototype results using data from the EOS Terra platform are presented.
