  • Micropulse Lidar Cloud Mask VAP Data Revised for High-Latitude Sites

    Data reprocessed with a revised version of the Micropulse Lidar Cloud Mask value-added product (MPLCMASK VAP) are now available for four high-latitude sites. This reprocessing also includes periods of data previously listed as missing. The durations of missing data varied from several minutes to several hours and occurred periodically during the winter months. Affected fields…

  • Updated Micropulse Lidar Cloud Mask VAP in Production

    Sample Micropulse Lidar Cloud Mask (MPLCMASK) plots from the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition show the log10 (backscatter), linear depolarization ratio (LDR), and cloud mask for October 7, 2019. Production data for Atmospheric Radiation Measurement (ARM) user facility sites operating fast-switching polarized micropulse lidars are now available from an…

  • MPLCMASK Evaluation Data Available for MARCUS Campaign

    Sample plots from the MARCUS deployment show the log10 (backscatter) and the LDR for a selected range and UTC time for February 18, 2018. An updated version of the Micropulse Lidar Cloud Mask (MPLCMASK) value-added product (VAP) provides cloud boundaries and linear depolarization ratio (LDR) for the Measurements of Aerosols, Radiation, and Clouds over the…

  • Lidar Value-Added Product Provides Cloud Measurements

    Sample plot generated by MPLCMASK. Click to enlarge. Lidar cloud boundaries are a useful tool for identifying cloud base height and cloud thickness in optically thin clouds. The Micropulse Lidar Cloud Mask (MPLCMASK) value-added product (VAP) provides cloud base height, cloud top height, and backscatter coefficient for non-polarized micropulse lidar measurements. In addition, depolarization ratio…
