TROPESS TCR-2: Anthropogenic NOx Emissions, Monthly Global Grid

TROPESS Chemical Reanalysis Surface Anthropogenic NOx emissions Monthly 2-dimensional Product contains nitrogen oxides (NO and NO2) emissions from anthropogenic sources. The data are part of the Tropospheric Chemical Reanalysis v2 (TCR-2) for the period 2005-2021, produced using JPL's MOMO-Chem data assimilation framework. Data files are in netCDF format, providing a year of monthly data at a spatial resolution of 1.125 x 1.125 degrees.

Use Cases

• Analyzing trends in human-caused nitrogen oxide emissions over a 17-year period.
• Validating and calibrating atmospheric chemistry models using assimilated satellite observations.
• Mapping the spatial distribution of NOx emissions on a global 1.125-degree grid.
• Investigating seasonal and interannual variability in anthropogenic air pollution sources.

Strengths

• Provides a 17-year continuous time series (2005-2021) of monthly emissions.
• Uses a sophisticated multi-species, multi-model data assimilation framework (MOMO-Chem) to optimize emissions.
• Offers a consistent global spatial grid at 1.125 x 1.125 degrees.

Limitations

• Column names and detailed variable metadata are not provided in the source descriptions.
• The dataset's license is ambiguously described as 'other-license-specified' without details.
• The spatial resolution (1.125 degrees) may be too coarse for localized or urban-scale studies.
