Abstract
Ground-based, low-cost, uncooled infrared imagers are specially calibrated and deployed for long-term measurements of spatial and temporal cloud statistics. Measurements of cloud optical depth are shown for thin clouds, and validated with a dual-polarization cloud lidar. Good comparisons are achieved for thin clouds having 550-nm optical depth of 3 or less.
