DLPROF-WIND

ARM operates several scanning coherent Doppler lidar systems at various sites around the globe. These instruments operate in the near infrared (1.5 microns) and provide measurements of radial velocity, attenuated aerosol backscatter, and signal-to-noise ratio. Systems are typically operated using a fixed scan schedule consisting of plan-position-indicator (PPI) scans that are performed several times per hour and vertically pointing during other times. The DLPROF-WIND value-added product calculates profiles of horizontal winds from the PPI scans. These wind measurements in the atmospheric boundary layer are particularly important for modeling pollutant and aerosol transport.
