Subvisual cirrus detection via a multi-spectral decomposition method

Lidar data collected on September 15, 1988 over Dayton (Ohio) were synchronized with NOAA satellite observations in order to investigate the feasibility of discriminating between observations of subvisual cirrus, other cirrus, and clear sky. It is concluded that the detection of subvisual cirrus currently requires 'ground-truth' information, such as lidar measurements, for cloud height determinations and for verification.
