    • GPM Ground Validation Cloud Physics LiDAR (CPL) OLYMPEX V1

    Metadata Updated: February 6, 2026

    The GPM Ground Validation Cloud Physics Lidar (CPL) OLYMPEX dataset consists of extinction profiles, layer optical depth, layer lidar ratio, and aircraft parameter measurements measured by the CPL flown on the NASA ER-2 aircraft during the Global Precipitation Mission (GPM) Olympic Mountains Experiment (OLYMPEX) campaign. The CPL instrument is a multi-wavelength backscatter lidar that provides multi-wavelength measurements of cirrus and aerosols with high temporal and spatial. Data files are available from November 9, 2015 through December 15, 2015 in HDF-5 format with layer information in ASCII text files. Browse imagery files in GIF format contain optical depth and flight path images.
