  • WACR-ARSCL Evaluation Data Available for MARCUS Field Campaign

    From top to bottom, these images from the MARCUS WACR-ARSCL VAP show best-estimate reflectivity, non-ship-corrected mean Doppler velocity, and ship-corrected mean Doppler velocity for November 28, 2017. A value-added product (VAP) that combines observations from the marine version of the 95 GHz W-Band ARM Cloud Radar (WACR) and other ARM mobile instruments now provides datastreams…

  • Merged Multisensor Cloud-Precipitation Mask and Cloud Type Data Now Available for GoAmazon2014/15

    The example plot shown here is from a merged RWP-WACR-ARSCL data set. Key: a) WACR reflectivity; b) RWP reflectivity; c) new RWP-WACR-ARSCL cloud mask; d) cloud-type classification; e) microwave radiometer (MWR) retrieved liquid water path (blue), present weather detector (PWD) rain rate (black), and tipping bucket rain rate (red). The black dots in panels (a,…

  • ARM Cloud Radar-Remote Sensing Evaluation Data Available for LASIC Campaign

    Plots from the WACR-ARSCL value-added product show reflectivity best estimate (top) and mean Doppler velocity (bottom) as captured February 22, 2017, during the LASIC field campaign on Ascension Island. Evaluation data for the W-Band ARM Cloud Radar-Active Remote Sensing of Clouds (WACR-ARSCL) value-added product are now available for the ARM Mobile Facility deployment to Ascension…

  • New WACR Radar Data Available for AWARE Campaign

    Best estimate reflectivity data from the WACR-ARSCL value-added product are shown here for the AWARE field campaign on January 3, 2016. The W-band ARM Cloud Radar-Active Remotely Sensed Cloud Locations (WACR-ARSCL) provides cloud boundaries and best-estimate time-height fields of radar moments. WACR observations are corrected for velocity aliasing, and then significant detection masks are produced.…

  • An Update of WACR-ARSCL: Evaluation VAP Data Available

    A data plot example is shown here from Hyytiälä, Finland, for July 1, 2014. New data sets from the 95 GHz W-band ARM Cloud Radar-Active Remote Sensing of Clouds (WACR-ARSCL) are now available for download as an evaluation value-added product (VAP) for the ARM Mobile Facility (AMF) deployments in Hyytiälä, Finland, from February through September…

  • New Best Estimate Data Available for WACR-ARSCL

    A data plot from the WACR-ARSCL Reflectivity Best Estimate from Graciosa Island, Azores, is shown for June 27, 2009. New data from the 95 GHz W-band ARM Cloud Radar-Active Remote Sensing of Clouds (WACR-ARSCL) value-added product (VAP) (Kollias and Miller, 2007) are now available in the ARM Data Archive. In addition to the WACR data,…

  • Vertical Air Motion Profiles Available Through New Value-Added Product

    In the top figure, evidence of stratiform precipitation is observed in the WACR reflectivity profiles. Vertical air motion is retrieved from the WACR velocity spectra for hours 900 to 1200 as depicted on the lower left. An overview of the VAP algorithm is displayed on the lower right. Click to enlarge.The Vertical Air Motion during…

  • Black Forest, Germany, WACR-ARSCL Evaluation Products Now Available

    Observations from the 95 GHz W-band ARM Cloud Radar (WACR), Micropulse Lidar, and ceilometer have been combined using the new WACR-Active Remote Sensing of Clouds (WACR-ARSCL) value-added process (VAP) (Kollias and Miller, 2007) to produce cloud boundaries and time-height profiles of cloud location, radar moments, and linear depolarization ratio fields for the ARM Mobile Facility…
