Abstract

This paper describes a project on automating the interpretation of cloud images recorded during several types of atmospheric observations: (1) dust clouds generated by controlled explosions, (2) chemical releases of infrared-active gases, and (3) lidar measurements of cloud altitude winds. This program began with a basic cloud tracking system for lidar comparisons, which has since been upgraded. We describe automated methods for tracking clouds of relatively constant shape, segmenting time-dependent clouds and plumes from scenic backgrounds, characterizing cloud and plume shapes, and measuring the speed and direction of cloud motion. Dust clouds were created by fireworks, releases of pressurized aerosols and by propane-driven blast tubes. Chemical clouds of organic vapors were created by evaporation or with pressurized balloon releases. Cloud imagery for particle releases was recorded primarily with a pair of visible video cameras. The chemical clouds were imaged with a high framing rate infrared camera in the 2.5 – 3.5 micron region. Current project goals include an end-to-end system for cloud warnings, wind measurement, and dispersion predictions in real time.
