Large aerosols (approximately 150 micro-meter in diameter) were released from a blimp and tracked by NRL's millimeter wave radar (WARLOC) and NRL Eye-safe Volume Imaging Lidar (NEVIL). The releases simulated an elevated release of aerosols in an urban or coastal setting.
This photo shows the blimp as seen by the camera located on the lidar scanning system.
This image shows lidar-observed backscatter over 10 seconds as the aerosol disperses. The range distances are relative to the blimp location.
