Olympic Mountains Rain Gauge Pairs for Satellite Validation

Met One tipping bucket rain gauge pairs collected precipitation amount and rate data during the Olympic Mountains Experiment (OLYMPEX) field campaign. The campaign, led by NASA's Global Precipitation Measurement mission, took place from November 2015 to February 2016 on the Olympic Peninsula in the Pacific Northwest. This dataset provides ground-truth measurements to validate precipitation observations from the GPM Core Observatory satellite.

Use Cases

• Validating satellite-derived precipitation rates from the GPM Core Observatory against ground-based measurements.
• Analyzing temporal patterns of precipitation amount and rate during winter storms in the Pacific Northwest.
• Studying the influence of complex terrain (Olympic Mountains) on precipitation distribution and intensity.
• Comparing precipitation data from paired gauges at individual station platforms for instrument reliability assessment.

Strengths

• Data collection was part of a targeted NASA field campaign (OLYMPEX) designed specifically for satellite validation.
• Measurements cover a full winter season from November 2015 through February 2016.
• Data is collected from paired rain gauges at each station, allowing for internal consistency checks.

Limitations

• Specific column names, row counts, and total dataset size are not provided by any source.
• Sources conflict on the data availability end date (June 20, 2016 vs. campaign end in February 2016) and the last update date (2026 vs. 2016).
• The exact license is ambiguous, listed as 'other-license-specified' on some platforms and 'None' on others.
