OLYMPEX Weather Radar Data for Precipitation Validation

GPM Ground Validation CAX1 Radar CFradial format OLYMPEX dataset contains radar parameters from a SELEX Meteor 60DX10 Compact Weather radar. Environment and Climate Change Canada operated the radar from Vancouver Island during the OLYMPEX field campaign. Data are available in netCDF-4 format covering November 14, 2015 through April 1, 2016.

Use Cases

• Validating satellite-derived precipitation estimates from the GPM mission using ground-based radar reflectivity measurements.
• Analyzing storm structure and microphysics using differential reflectivity and Doppler velocity columns.
• Studying winter precipitation patterns in the Pacific Northwest using time-series data from the OLYMPEX campaign period.
• Calibrating hydrological models with high-resolution (0.4-1.0 km) spatial radar data.

Strengths

• Data originates from a specific, well-documented field campaign (OLYMPEX) supporting the GPM mission.
• Provides multiple calibrated radar parameters including reflectivity, Doppler velocity, and differential reflectivity.
• Covers a continuous nearly five-month period from November 2015 to April 2016.

Limitations

• Exact dataset size, row count, and column details are not provided by any source.
• Sources conflict on license information, with one specifying 'other-license-specified' and another listing 'None'.
• Data is confined to a single radar location and a specific campaign timeframe, limiting generalizability.
