Canadian Winter Weather Station Data for Satellite Validation

October 4, —2006 through March 31, 2007 surface meteorological measurements from the Environment Canada XET station during the C3VP field campaign in southern Canada. This dataset, produced by NASA, includes temperature, pressure, wind, humidity, solar radiation, soil temperature, snow depth, and precipitation to support the validation of satellite remote sensing models for winter precipitation.

Use Cases

• Validating satellite-derived precipitation estimates from missions like GPM and CloudSat using ground-truth precipitation and snow depth measurements.
• Analyzing relationships between surface conditions (soil temperature, grass temperature) and atmospheric variables (air temperature, humidity) during winter.
• Studying surface energy budgets in winter using solar radiation, sunshine duration, and temperature columns.
• Correlating wind speed and direction data with precipitation patterns to understand storm dynamics.
• Using the multi-parameter time-series to calibrate or improve hydrological and atmospheric models for snow-dominated regions.

Strengths

• Provides a focused six-month time series covering a full winter season from October 2006 to March 2007.
• Contains a multi-faceted set of over ten surface meteorological variables, including less common measurements like grass temperature and sunshine.
• Data is associated with a formal international validation campaign (C3VP) supporting NASA's GPM mission.

Limitations

• Exact row count, file size, and column structure are unspecified across all sources.
• Sources conflict on the last updated date: one lists 2007-03-31, another lists 2026-03 13, suggesting potential metadata inconsistency.
• License is ambiguously listed as 'other-license-specified' without explicit terms.
