MSUOP: Daily Oceanic Precipitation Estimates from Microwave Sounding Units

Global oceanic precipitation data derived from Microwave Sounding Unit (MSU) instruments on multiple satellite platforms. The product uses a method from 1993, estimating precipitation by measuring thermal emission near 60 GHz and correcting for atmospheric warming. It is provided by NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) and was last updated in March 2026.

Use Cases

• Modeling global oceanic precipitation trends based on microwave emission data.
• Validating climate model outputs against satellite-derived temperature and precipitation estimates.
• Analyzing the relationship between upper tropospheric temperatures and liquid water precipitation.
• Studying long-term changes in atmospheric warming attributable to liquid water emission.

Strengths

• Data is derived from multiple satellite platforms, likely providing broad spatial coverage.
• Applies a peer-reviewed correction method (Limb93) for atmospheric warming.
• Last updated date is explicitly provided (2026-03-12).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data is limited to oceanic regions and derived from a specific sensor type (MSU).
