TRPSCRENOXLM2D: Lightning NOx Emissions Reanalysis 2005-2021

Monthly nitrogen oxides (NO and NO2) emissions from lightning strikes are provided from 2005 to 2021. The data 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. Each netCDF file contains a year of data at a 1.125 x 1.125 degree spatial resolution.

Use Cases

• Validating and improving atmospheric chemistry models based on assimilated satellite observations.
• Analyzing interannual variability and trends in lightning-generated NOx emissions over a 17-year period.
• Studying the spatial distribution of a natural NOx source on a global 1.125-degree grid.
• Providing prior emission estimates for regional air quality studies based on the TCR-2 reanalysis framework.

Strengths

• Covers a 17-year time range (2005-2021), enabling long-term trend analysis.
• Uses a sophisticated multi-species data assimilation framework (MOMO-Chem) to optimize emissions.
• Provides data on a consistent global grid with a defined 1.125 x 1.125 degree spatial resolution.
• Cross-platform presence on NASA Earthdata and Data.gov signals its importance and curation.

Limitations

• Specific column names and row counts are not provided in the available metadata, limiting precise understanding of the data structure.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
• Data freshness is unclear; the last update date is provided but may reflect metadata revision, not new data.
