GHRSST MUR: Global Sea Surface Temperature Analysis at 0.25 Degree Resolution

A global 0.25 degree resolution sea surface temperature analysis produced by the JPL Physical Oceanography DAAC. The dataset integrates nighttime skin and subskin SST observations from multiple satellite instruments, including AMSR-E, MODIS, WindSat, and AVHRR, along with in-situ data from NOAA iQuam. It was created under the NASA MEaSUREs program and adheres to GHRSST Data Processing Specification version 2 format.

Use Cases

• Modeling ocean-atmosphere heat exchange based on global foundation sea surface temperature data.
• Analyzing long-term SST anomalies based on the derived anomaly variable from a 2003-2014 climatology.
• Improving high-latitude SST parameterization based on integrated ice concentration data from OSI SAF.
• Validating satellite-derived SST products based on the multi-sensor optimal interpolation approach.

Strengths

• Integrates data from at least seven distinct satellite instruments and in-situ sources.
• Provides a derived SST anomaly variable based on a defined 2003-2014 climatology.
• Uses an optimal interpolation approach on a global 0.25 degree grid for consistent resolution.
• Includes ice concentration data for improved high-latitude SST parameterization.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
