GPM Ground Validation FD12P: Visibility and Precipitation Data from C3VP Campaign

NASA's GPM Ground Validation Environment Canada Visibility Sensor FD12P C3VP dataset contains visibility and precipitation measurements collected at the Centre for Atmospheric Research Experiments (CARE) site in southern Canada. Data were gathered during the Canadian CloudSat/CALIPSO Validation Project field campaign from October 4, 2006, through March 31, 2007, to support the modeling and remote sensing of winter precipitation. The dataset is formatted as a Microsoft Excel comma-separated variable spreadsheet.

Use Cases

• Validating satellite-based precipitation estimates from the GPM mission using ground-based sensor data.
• Improving numerical weather prediction models for winter precipitation events with in-situ visibility and precipitation measurements.
• Analyzing temporal patterns of atmospheric visibility and precipitation rates during a winter field campaign.
• Supporting research on the remote sensing of snowfall and mixed-phase precipitation.

Strengths

• Data collected during a dedicated, multi-mission field campaign (C3VP) supporting NASA's GPM mission.
• Provides a specific, continuous time range of observations from October 2006 to March 2007.
• Hosted by a major space agency (NASA), indicating institutional oversight.

Limitations

• Column names and a precise row count are not provided in any source, limiting understanding of data structure.
• Sources conflict on the last updated date (2007 vs. 2026), raising questions about metadata maintenance.
• The license is ambiguously listed as 'other-license-specified' without further details.
