TRPSCRECOTM2D: Global Surface Carbon Monoxide Emissions, 2005-2021

TROPESS Chemical Reanalysis Surface Total CO emissions Monthly 2-dimensional Product provides a global estimate of surface-level carbon monoxide emissions from all sources. The dataset is part of the Tropospheric Chemical Reanalysis v2 (TCR-2), generated using JPL's MOMO-Chem data assimilation framework that optimizes concentrations and emissions from multiple satellite sensors. Data are provided as netCDF files with monthly resolution at a 1.125 x 1.125-degree spatial grid.

Use Cases

• Analyzing long-term trends in global CO emissions based on the 2005-2021 time series.
• Validating regional emission inventories using the spatially gridded 2-dimensional product.
• Assimilating optimized emission estimates into atmospheric chemistry models using the MOMO-Chem framework outputs.
• Studying seasonal and interannual variability of total surface CO sources from the monthly resolution data.

Strengths

• Provides a 17-year continuous record (2005-2021) for analyzing long-term trends.
• Uses a sophisticated multi-species, multi-sensor data assimilation framework (MOMO-Chem) to optimize emissions.
• Offers consistent global coverage at a defined spatial resolution of 1.125 x 1.125 degrees.

Limitations

• Metadata completeness is low; specific column/variable names and row/file counts are not provided.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
• Data freshness is unclear; the last platform update is listed as 2026-04-09, but the core data ends in 2021.
