  • MOSAiC Doppler Lidar Motion Correction VAPs Now in Production

    Two value-added products (VAPs) specifically designed for the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition recently moved from evaluation to production. The Doppler Lidar Motion Correction (DLMC) VAP applies a motion correction to Doppler lidar (DL) measurements collected on the icebreaker R/V Polarstern during MOSAiC. The Doppler Lidar Motion Correction…

  • Wind Profiles Derived From Motion-Corrected MOSAiC Lidar Data

    A new value-added product (VAP) developed specifically for the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition is now available for evaluation. This VAP derives profiles from Doppler lidar measurements collected on the research icebreaker R/V Polarstern, which drifted through the central Arctic during MOSAiC. The Doppler Lidar Motion Correction Wind Profiles…

  • ARM Rolls Out New Products for Determining Boundary-Layer Height

    The structure and depth of the planetary boundary layer (PBL) are important to a wide range of atmospheric processes. Such processes include cloud formation and aerosol and chemical mixing, transport, and transformation. Errors in the determination of PBL height can significantly affect the formation and maintenance of low-level clouds and the initiation of convective clouds…

  • Doppler Lidar Data Products Released for 3 ARM Campaigns

    The Atmospheric Radiation Measurement (ARM) user facility operates Doppler lidars around the globe to provide measurements of radial velocity, attenuated aerosol backscatter, and signal-to-noise ratio. Systems are typically operated using a fixed scan schedule. Doppler lidar data are used to derive horizontal wind and vertical velocity statistics. The Doppler Lidar Wind value-added product (DLPROF-WIND VAP)…

  • Companion Data Sets Key In on Eastern North Atlantic Doppler Lidar

    Two new Doppler lidar principal investigator data sets are available from the Atmospheric Radiation Measurement (ARM) user facility’s Eastern North Atlantic (ENA) atmospheric observatory. Doppler lidars, which record backscatter and mean Doppler velocity, are sensitive to echoes from aerosols and hydrometeors. One of the new ENA data sets provides noise-filtered, calibrated backscatter to help distinguish…
