    • GPM GROUND VALIDATION TWO-DIMENSIONAL VIDEO DISDROMETER (2DVD) NSSTC V1

    Metadata Updated: September 19, 2025

    The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) NSSTC dataset was collected by the Two-Dimensional Video Disdrometer (2DVD), which uses two high speed line scan cameras which provide continuous measurements of size distribution, shape and fall velocities of all precipitation particles and types. This 2DVD is the third generation 2D video disdrometer designed by Joanneum Research of Graz, Austria. This dataset provides rainfall data for the Global Precipitation Measurement (GPM) Mission Ground Validation Experiment collected at the National Space Science Technology Center (NSSTC) in Hunstville, AL. There may be occasional gaps in the data when the instrument is not resident at the NSSTC and is sent to participate in field campaigns.
