Satellite Ocean Products Grid: Weekly Averages from DMSP F8

Global satellite data provides weekly averages of ocean wind speed, atmospheric water vapor, cloud liquid water, and rain rate. This dataset is part of NASA's MEaSUREs Program, produced by Remote Sensing Systems using a unified algorithm refined over 20 years. The netCDF collection originates from the DMSP F8 satellite's Special Sensor Microwave/Imager (SSM/I).

Use Cases

• Analyzing long-term trends in global ocean surface wind speeds.
• Modeling atmospheric water vapor content and its distribution.
• Studying the relationship between cloud liquid water and precipitation rates.
• Validating climate and weather models against satellite-retrieved rain rate data.
• Investigating interannual variability in key ocean-atmosphere parameters.

Strengths

• Data products are generated using a unified, physically based algorithm refined over a 20-year period.
• SSMIS data is intercalibrated to the brightness temperature level of previous SSM/I sensors, ensuring continuity for the time series.

Limitations

• Specific row counts, file sizes, and a complete column list are not provided by any source.
• Sources conflict on the last updated date, with one listing 1992-01-04 and another listing 2026-03 12.
