TRPSCRCOM3D: Global CO Concentrations from 2005-2021

The TROPESS Chemical Reanalysis CO Monthly 3-dimensional Product provides vertical concentrations of carbon monoxide globally from 2005 to 2021. It is generated by the Tropospheric Chemical Reanalysis v2 (TCR-2) using JPL's MOMO-Chem data assimilation framework, which optimizes concentrations and emissions from multiple satellite sensors. Data are stored as monthly files in netCDF format at a spatial resolution of 1.125 degrees and 27 pressure levels.

Use Cases

• Analyzing global carbon monoxide transport patterns based on 3D concentration fields
• Studying long-term trends in atmospheric pollution from 2005-2021 monthly data
• Validating emission inventories using the MOMO-Chem assimilation framework's optimized outputs
• Investigating vertical distribution of CO across 27 pressure levels from 1000 to 60 hPa

Strengths

• Provides a 17-year continuous record (2005-2021) for trend analysis
• Offers 3-dimensional data at 27 vertical pressure levels for detailed atmospheric structure
• Uses a sophisticated multi-species, multi-model assimilation framework (MOMO-Chem) to optimize both concentrations and emissions

Limitations

• Column names and detailed variable metadata are not provided in the available descriptions
• The spatial resolution of 1.125 degrees may be coarse for regional-scale studies
• Platform metadata shows conflicts: license is listed as 'other-license-specified' on some platforms but 'None' on others
