MERRA-2 M2TMNPODT: Monthly Ozone Tendencies on Pressure Levels

M2TMNPODT is a 3-dimensional monthly mean data collection from NASA's MERRA-2 global atmospheric reanalysis. It contains assimilations of ozone tendencies on 42 pressure levels, covering the period from 1980 to the present with a latency of about three weeks after each month. The dataset is produced by NASA's Global Modeling and Assimilation Office using the Goddard Earth Observing System Model version 5.12.4.

Use Cases

• Modeling total ozone analysis tendencies based on assimilated data
• Analyzing the tendency of odd oxygen mixing ratio due to chemistry
• Studying the tendency of ozone due to dynamics
• Investigating the tendency of odd oxygen due to moist processes
• Examining variance of ozone-related parameters

Strengths

• Covers a long temporal range from 1980 to present
• Provides data on 42 distinct pressure levels
• Includes variance data for certain parameters
• Produced by NASA's Global Modeling and Assimilation Office

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is provided in specialized formats like BIN and ISO
