The GPM Ground Validation Airborne Precipitation Radar 3rd Generation (APR-3) OLYMPEX dataset was collected from November 12, 2015 to December 19, 2015 during the GPM Ground Validation Olympic Mountains Experiment (OLYMPEX) field campaign held in the Pacific Northwest. APR-3 is the APR-2 used in previous field campaigns with the addition of W-band measurement capability. APR-3 beams scan cross-track from +/- 25° to the right and left of nadir. Ku-band, Ka-band and W-band frequency doppler measurements are made from the DC-8 aircraft at 10km altitude during OLYMPEX. The APR-3 dataset files are in HDF-4 format with PNG format browse images. This L1 APR-3 dataset provides radar reflectivity, doppler velocity for all bands, linear depolarization ratio at Ku-band, and normalized radar cross section measurements at Ka and Ku-bands.
