TRPSCRENOXSM2D: Global Soil NOx Emissions, 2005-2021

TROPESS Chemical Reanalysis v2 uses JPL's MOMO-Chem framework to assimilate satellite data, simultaneously optimizing both atmospheric concentrations and emissions. This dataset provides monthly, global estimates of nitrogen oxides (NO and NO2) released from surface soil sources. Each netCDF file contains a year of data at a spatial resolution of 1.125 x 1.125 degrees.

Use Cases

• Quantifying natural soil contributions to atmospheric NOx budgets based on the optimized emissions data.
• Evaluating and improving chemical transport model performance using the assimilated, multi-species reanalysis.
• Analyzing interannual variability and trends in soil emissions over the 17-year time range.
• Providing boundary conditions for regional air quality studies based on the global 2-dimensional product.

Strengths

• Provides a 17-year continuous record (2005-2021) for analyzing long-term trends.
• Data is produced using a sophisticated multi-model, multi-constituent chemical data assimilation framework (MOMO-Chem) from JPL.
• Simultaneously optimizes both concentrations and emissions, offering a physically consistent reanalysis.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable across all sources.
• The license is ambiguously listed as 'other-license-specified' without clear terms.
• Spatial resolution (1.125°) may be too coarse for local or regional-scale analysis.
