MERRA-2 M2TMNPUDT: Monthly Wind Tendencies on Pressure Levels

M2TMNPUDT is a 3-dimensional monthly mean data collection from NASA's MERRA-2 global atmospheric reanalysis. It contains assimilations of wind tendencies, such as total eastward wind analysis tendency and tendencies due to dynamics and turbulence, on 42 pressure levels. The dataset covers the period from 1980 to the present and is produced by NASA's Global Modeling and Assimilation Office using the GEOS model.

Use Cases

• Analyzing global wind tendency patterns based on assimilated eastward and northward wind data.
• Studying the contribution of dynamics and turbulence to wind changes based on the specified tendency parameters.
• Validating climate models using pressure-level wind tendency data from a long-term reanalysis.
• Investigating atmospheric variability and trends from 1980 onward using monthly mean wind tendency collections.

Strengths

• Data is produced by NASA's Global Modeling and Assimilation Office, an authoritative source.
• Coverage spans from 1980 to the present, providing a long-term record.
• Includes wind tendencies on 42 distinct pressure levels for detailed vertical analysis.

Limitations

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