GPM Ground Validation Airborne Precipitation Radar 3rd Generation (APR-3) OLYMPEX V2

The GPM Ground Validation Airborne Precipitation Radar 3rd Generation (APR-3) OLYMPEX V2 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. This dataset is version -2 (V2) of the APR-3, an enhanced and upgraded instrument derived from the APR-2 used in previous field campaigns. APR-3 has the addition of W-band measurement capability, and scans cross-track from +/- 25° to the right and left of nadir. Ku-band, Ka-band, and W-band frequency Doppler measurements are made by APR-3 from the DC-8 aircraft at 10 km altitude during OLYMPEX. The APR-3 dataset files are in HDF-5 format with JPG format browse images. This dataset contains radar reflectivity, Doppler velocity for all bands, linear depolarization ratio at Ku-band, and normalized radar cross section measurements at Ka and Ku-bands.
