Monthly Atmospheric Carbon Monoxide and Ozone Diagnostics from 1980

1980 to present monthly mean data from NASA's MERRA-2 atmospheric reanalysis. This collection provides assimilated diagnostics for carbon monoxide properties and total column ozone. It is produced by NASA's Global Modeling and Assimilation Office using the GEOS model.

Use Cases

• Modeling long-term trends in carbon monoxide column burden and surface concentration over the satellite era.
• Analyzing spatial and temporal variance in total column ozone from 1980 to the present.
• Studying global carbon monoxide emission and chemical production rates using monthly assimilated data.
• Validating atmospheric chemistry models against the reanalysis data for carbon monoxide and ozone parameters.

Strengths

• Covers a multi-decade period from 1980 to the present.
• Provides assimilated data combining models and observations for accuracy.
• Includes variance metrics for certain atmospheric parameters.

Limitations

• Data has a latency of approximately three weeks after each month ends.
• Specific row counts, file sizes, and spatial resolution details are not provided in the input.
• Reprocessing events can lead to filename changes, requiring user awareness.
