MERRA-2 M2T3NENAV: 3-Hourly Atmospheric Vertical Coordinates

73 model layer edges provide vertical coordinates, including edge pressure and edge heights, for the NASA MERRA-2 global atmospheric reanalysis. The data is available every three hours starting from 01:30 UTC and covers the period from 1980 to the present. This collection is produced by NASA's Global Modeling and Assimilation Office using the Goddard Earth Observing System Model version 5.12.4.

Use Cases

• Modeling atmospheric vertical profiles based on edge pressure and edge heights.
• Analyzing time-series trends in atmospheric layer boundaries based on 3-hourly data.
• Integrating vertical coordinate data with other MERRA-2 reanalysis components for comprehensive climate studies.

Strengths

• 73 distinct model layer edges provide detailed vertical resolution.
• Data is updated with a latency of approximately 3 weeks after the end of each month.
• Time-averaged data points are available at a 3-hourly frequency.

Limitations

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