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

The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) HyMeX data was collected during the HYdrological cycle in Mediterranean EXperiment (HyMeX), which provided data on raindrop size and precipitation drop size distribution. The 2DVD measured the size of raindrops and also recorded two side view optical images of each raindrop. Used for in situ measurements of precipitation drop size distribution, this instrument recorded orthogonal image projections of raindrops as they crossed its sensing area and provided velocity and shape of individual raindrops.The HyMeX 2DVD data were collected in France and Italy from September 12, 2012 to November 12, 2012. The data are in ASCII format.

Wind Solar Wind Experiment (SWE) Strahl Detector Two Dimensional Electron Angular Distributions, (H4), 12 s Data

Explanatory Notes: The 2D Electron Angular Distributions included in this Data Set were measured by the Wind/SWE Strahl Detector (see Ogilvie et al., "SWE, a Comprehensive Plasma Instrument for the Wind Spacecraft", Space Sci. Rev., 71, 55, 1995). Each Angular Distribution was measured at a single Electron Energy. The Energy was selected by applying a Voltage between the Electrostatic Analyzer Plates. The Detector sampled 32 Energies between 19 eV and 1238 eV, and during normal Operation would Sweep through these Energies one at a Time with approximately 12 s Cadence. The 12 Anodes of the Instrument are set in a vertical Pattern in a Plane that contains the Spacecraft Spin Axis, spanning a Field of View +/-28° centered around the Ecliptic (with uneven Angular spacing between Anodes). The Wind Spacecraft Spin Axis is set at a Right Angle with the Ecliptic Plane, allowing different Azimuthal Angles to be sampled as the Spacecraft Spins (3 s Spin Period). These Azimuthal Bins have a Fixed Separation of 3.53°. Each Strahl (and Antistrahl) Distribution measured by the Spacecraft consists of a 14 ⨯ 12 Angular Grid of Electron Counts, that was measured at a Fixed Energy during a single Spacecraft Spin. Counts are converted into Physical Units of f(v) (e.g., cm^-6s^3) in the standard Fashion by accounting for the Detector Efficiency and Geometric Factor. The Data Set reported here contains: f_strahl, f_antistrahl, f_strahl_counts, f_antistrahl_counts, phi_strahl, phi_antistrahl, theta, energy.

GPM GROUND VALIDATION TWO-DIMENSIONAL VIDEO DISDROMETER (2DVD) MC3E V1

The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) MC3E dataset was collected during the Midlatitude Continental Convective Clouds Experiment (MC3E), which provides data on raindrop size and precipitation drop size distribution.

The experiment was a collaborative effort between the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility and the National Aeronautics and Space Administration's (NASA) Global Precipitation Measurement (GPM) mission Ground Validation (GV) program. The field campaign leveraged the unprecedented observing infrastructure currently available in the central United States, combined with an extensive sounding array, remote sensing and in situ aircraft observations, NASA GPM ground validation remote sensors, and new ARM instrumentation purchased with American Recovery and Reinvestment Act funding. The overarching goal was to provide the most complete characterization of convective cloud systems, precipitation, and the environment that has ever been obtained, providing constraints for model cumulus parameterizations and space-based rainfall retrieval algorithms over land that had never before been available.
