  • New Data Available From Updated Raman Lidar Value-Added Product

    This figure provides sample plots from ARM’s Southern Great Plains Central Facility Raman lidar on May 25, 2020. The top plot shows a time-height cross-section of the merged photon counting rates for the narrow-field-of-view elastic (355 nm) channel. The middle plot shows cloud base height estimates, and the bottom plot shows the so-called “merge flag.”…

  • Reprocessed Raman Lidar Data Now Available

    This comparison plot shows the improved detection of cirrus and anvil clouds using the Raman and micropluse lidar data.Raman Lidar data obtained at the Darwin site have been reprocessed with an improved cloud mask, attenuation flag, and extended height range to 20 kilometers. Data are now available at 2-minute and 10-minute resolution for the Raman…

  • New Aerosol Best-Estimate Data Available as Value-Added Product

    Quicklook plots of monthly time series are generated for column AOD, vertical profiles up to 4 km of SSA and g, and for the corresponding RH profile. The optical properties are shown for the nominal green wavelength of 500 nm. The Aerosol Best Estimate (ABE) value-added product (VAP) provides best-estimate time series of total column…

  • Raman Lidar Data Product Suite Provides Best-Estimate Data

    Example of plots produced by the Raman lidar best-estimate VAP for April 3, 2011. Panels (a), (b), and (c) show time-height cross-sections of relative humidity, aerosol backscatter coefficient, and aerosol depolarization. A time series of aerosol optical depth is shown in panel (d). Click to view full-size image. Science data products derived from the Raman…
