Olympic Peninsula Satellite Overpass Data for GPM Validation

November 2015 through May 2016 data provides brightness temperature, precipitation, and total column water vapor estimates from multiple satellite overpasses for the OLYMPEX field campaign. This dataset supports ground-based validation of the Global Precipitation Measurement (GPM) Core Observatory satellite findings. It was collected and is maintained by the GHRC DAAC.

Use Cases

• Validating GPM satellite precipitation retrievals using ground-based campaign data.
• Analyzing spatial patterns of brightness temperature across the Olympic Peninsula.
• Studying correlations between total column water vapor and precipitation rates.
• Comparing precipitation estimates from multiple satellite platforms (DMSP, GCOM-W1, MetOp, NOAA, NPP).

Strengths

• Covers a focused 7-month field campaign period from November 2015 to May 2016.
• Integrates overpass data from at least seven distinct satellite platforms for cross-validation.
• Specifically designed for ground validation of the GPM Core Observatory mission.

Limitations

• Exact row count, file size, and detailed column names are not provided by any source.
• License information conflicts between 'other-license-specified' and 'None' across platforms.
