TRPSCRENOXBM2D: Monthly Global Biomass Burning NOx Emissions

NASA's TROPESS Chemical Reanalysis Surface Biomass Burning NOx emissions product provides a global, monthly record of nitrogen oxides (NO and NO2) emissions from fires. The data are generated using JPL's MOMO-Chem data assimilation framework, which optimizes emissions and concentrations by assimilating observations from multiple satellite sensors. It covers the period 2005-2021 at a spatial resolution of 1.125 x 1.125 degrees.

Use Cases

• Analyzing interannual trends in fire-related NOx emissions based on the 2005-2021 time series.
• Validating or constraining atmospheric chemistry models using the data-assimilated emission estimates.
• Studying the spatial distribution of biomass burning emissions at a 1.125-degree resolution.
• Investigating the coupling between fire activity and tropospheric nitrogen chemistry.

Strengths

• Provides a 17-year continuous record (2005-2021) for analyzing long-term trends.
• Uses a sophisticated multi-species data assimilation framework (MOMO-Chem) to optimize emissions.
• Has a defined spatial resolution of 1.125 x 1.125 degrees and monthly temporal resolution.

Limitations

• Column names and specific variable definitions are not provided in the available metadata.
• The license is ambiguously listed as 'other-license-specified' without clear terms.
• Data freshness is unclear; the last metadata update is listed as 2026, but the record ends in 2021.
