Rain Gauge Measurements from NASA ACHIEVE IPHEx Campaign

May 9, 2014 through June 14, 2014 data was collected during the Integrated Precipitation and Hydrology Experiment (IPHEx) in North Carolina. The dataset contains high-sensitivity optical and tipping bucket rain gauge measurements from NASA's ACHIEVE mobile laboratory, providing precipitation rate, cumulative precipitation, and temperature. It is managed by the GHRC DAAC and serves as ground validation for the Global Precipitation Measurement (GPM) mission.

Use Cases

• Validating satellite-based precipitation estimates from the GPM mission using ground-based rain gauge data.
• Analyzing temporal patterns of precipitation rate and 24-hour cumulative rainfall during a focused field campaign.
• Comparing measurements from high-sensitivity optical rain gauges with standard tipping bucket gauge readings.
• Studying the relationship between precipitation and temperature in a ground-based mobile laboratory setting.

Strengths

• Data originates from a controlled NASA field campaign (IPHEx) with a defined time range of May 9 to June 14, 2014.
• Includes measurements from two distinct instrument types (optical and tipping bucket) for comparative analysis.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata and Data.gov), indicating curation and importance.

Limitations

• Specific row count, file size, and complete column names are not provided by any source.
• Sources conflict on the last updated date, reporting either 2014-06-15 or 2026-03 13.
• License is ambiguously listed as 'other-license-specified' or 'None' across different entries.
