Suominet is a network of ground-based GPS receivers and meteorological sensors used to estimate column precipitable water vapor. Hourly reports include surface pressure, temperature, humidity, and water vapor data, spanning from June 2001 to the present. The archive includes real-time and post-processed reports from the global network.
Use Cases
- Model atmospheric water vapor distribution based on GPS-derived column precipitable water vapor estimates.
- Analyze surface weather conditions based on hourly surface pressure, temperature, and humidity reports.
- Study long-term trends in atmospheric moisture based on data spanning from 2001 to the present.
- Compare real-time and post-processed atmospheric measurements for accuracy assessment.
Strengths
- Data spans a long temporal range from June 2001 to the present.
- Includes multiple atmospheric variables: surface pressure, temperature, humidity, and estimated water vapor.
- Provides both real-time and post-processed reports for potential quality comparison.
Limitations
- Last updated metadata is from 2014-09-30; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Update intervals are described as irregular, which may affect data continuity.
