    • GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) OLYMPEX V1

    Metadata Updated: April 10, 2026

    The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) OLYMPEX dataset contains information on individual hydrometeors including their size distribution, terminal fall speed, and total concentration collected during the Global Precipitation Measurement mission (GPM) Ground Validation (GV) Olympic Mountains Experiment (OLYMPEX). The OLYMPEX field campaign took place between November 2015 and January 2016, with additional ground sampling continuing through February 2016, on the Olympic Peninsula in the Pacific Northwest of the United States. The purpose of the campaign was to provide ground-validation data for the measurements taken by instrumentation aboard the GPM Core Observatory satellite. The Two-Dimensional Video Disdrometer (2DVD) data were collected from four sites during the campaign. The dataset files are available from October 31, 2015 through January 17, 2016 (though the exact dates may vary per site) in ASCII-tsv format.
