Abstract:

A suite of instruments is described that measure the parameters required as sea truth for a shipborne lidar system. Novel optical configurations are used with digital electronics to efficiently measure beam transmission, backscattering, beam-spread function, and diffuse spectral attenuation. All sensors are linked to a single desktop computer for data collection and analysis in near-real-time at sea. The instrumentation is described, and representative data are presented. Author
