The Global Argo Data Repository archives monthly profile data collected by Argo profiling floats since September 1995. NOAA NCEI operates the repository, containing real-time and delayed-mode profiles of ocean temperature, salinity, pressure, conductivity, dissolved oxygen, nitrate, pH, chlorophyll a, backscattering, and downwelling irradiance. Data collection began in 1995 and monthly archiving started in the second quarter of fiscal year 2003.
Use Cases
- Modeling global ocean temperature changes based on monthly profile data.
- Analyzing salinity distributions for climate research based on float measurements.
- Studying marine biogeochemistry based on profiles of dissolved oxygen, nitrate, and chlorophyll a.
- Calibrating satellite oceanographic data based on in-situ pressure and conductivity measurements.
- Investigating long-term oceanographic trends based on data collected since 1995.
Strengths
- Data collection spans from September 1995 to the present, providing a long-term record.
- Monthly archiving since April 2003 ensures regular updates.
- Profiles include multiple biogeochemical parameters like dissolved oxygen, nitrate, and chlorophyll a.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
