Weekly gridded Level-3 sea surface salinity (SSS) retrievals from the NASA-CONAE Aquarius/SAC-D mission. The dataset provides polar-gridded observations derived from L-band radiometer measurements. It was produced by NASA and Argentina's CONAE, with data last updated in June 2015.
Use Cases
- Analyzing weekly sea surface salinity (SSS) anomalies and trends in polar oceans using the gridded data fields.
- Validating ocean circulation and freshwater flux models by comparing against the satellite-retrieved salinity values.
- Investigating the relationship between polar sea ice melt and near-surface ocean salinity from the polar-gridded observations.
- Assessing seasonal and interannual variability of SSS in high-latitude regions using the time-series of weekly gridded products.
Strengths
- Data is processed to Level-3, indicating gridded and spatially interpolated products for ease of use.
- Provides weekly temporal resolution for monitoring short-term salinity changes.
- Focus on polar regions offers specific coverage for critical climate zones.
Limitations
- Data recency is limited, with last update in 2015, ending with the Aquarius mission.
- Specific spatial resolution, row count, and validation metrics are unknown from the description.
- Coverage is limited to polar-gridded areas, not providing a full global view.
