GPM IFloodS: Ground Validation Campaign Reports

GPM Ground Validation Campaign Reports IFloodS V1 consists of reports filed by scientists during the Iowa Flood Studies (IFloodS) field experiment from April to mid-June 2013. The dataset includes Mission Scientist, Instrument Scientist, and Weather Forecast reports, often with attachments, documenting the campaign to collect detailed surface precipitation measurements. Its cross-platform presence on Data.gov and NASA Earthdata signals its importance for satellite precipitation validation.

Use Cases

• Validating satellite-based precipitation estimates using ground instrument and radar measurements.
• Analyzing field campaign logistics and operational decisions documented in Mission Scientist reports.
• Studying instrument performance and calibration during a major precipitation field experiment.
• Reviewing weather forecasts used to plan daily mission activities during the IFloodS campaign.

Strengths

• Provides detailed, contemporaneous documentation from a major NASA-led field campaign.
• Contains multimodal content, including text reports and file attachments.
• Is hosted by authoritative sources, including NASA and the U.S. government.

Limitations

• Column names and a precise row count are not provided by any source, limiting structured analysis.
• Sources conflict on the last update date (2014 vs. 2026), creating uncertainty about metadata freshness.
• The dataset's size and exact file formats beyond PDF, BIN, ISO, and HTML are unspecified.
