Aquarius Satellite Seasonal Climatology of Sea Surface Density

Seasonal climatology data for sea surface density, derived from the Aquarius/SAC-D satellite's descending passes. The dataset contains gridded 1-degree spatial resolution maps, with density estimates based on the TEOS-10 standard using retrieved salinity and collocated sea surface temperature. It is produced by NASA and CONAE as part of the Aquarius mission's Version 5.0 data release.

Use Cases

• Modeling ocean circulation and climate patterns based on seasonal sea surface density maps.
• Analyzing long-term density climatology for climate change studies based on gridded 1-degree data.
• Validating oceanographic models using satellite-derived density estimates from the TEOS-10 standard.
• Studying the relationship between sea surface salinity, temperature, and density from collocated satellite data.

Strengths

• Data is derived from a dedicated satellite instrument (Aquarius) with three radiometers and a scatterometer for corrections.
• Provides a 1-degree spatial resolution global grid for consistent analysis.
• Produced through a collaborative effort between NASA and the Argentinian Space Agency (CONAE).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
