GPM Ground Validation Ikaalinen C-Band Radar Data for LPVEx

October 19, 2010 radar reflectivity data was collected by the Ikaalinen dual-polarimetric C-Band Doppler radar in Finland. This dataset supports the Global Precipitation Measurement (GPM) mission's Light Precipitation Validation Experiment (LPVEx), aimed at improving satellite precipitation algorithms for high-latitude, light rainfall systems. The data is provided by NASA and is available in RAW and UF file formats.

Use Cases

• Calibrating and validating GPM satellite precipitation retrieval algorithms using ground-based radar reflectivity measurements.
• Analyzing the microphysical structure of light precipitation events in high-latitude climates like the Gulf of Finland.
• Studying dual-polarimetric radar signatures for specific precipitation types captured on a single campaign day.

Strengths

• Data originates from a NASA-led field campaign (LPVEx) designed for satellite algorithm validation.
• Provides measurements from a specific dual-polarimetric C-Band radar, offering detailed reflectivity data.
• Focuses on the under-sampled meteorological context of high-latitude light precipitation.

Limitations

• Temporal coverage is extremely limited to a single day (October 19, 2010).
• Specific column names, row counts, and dataset size are not documented across any source.
• License information is unclear, listed as 'other-license-specified' on one platform and null on another.
