TRPSCRNO2M3D: Global Nitrogen Dioxide Vertical Concentrations

Global monthly 3-dimensional concentrations of nitrogen dioxide (NO2) from 2005 to 2021. The data are part of the Tropospheric Chemical Reanalysis v2 (TCR-2), produced using JPL's MOMO-Chem data assimilation framework that optimizes concentrations and emissions from multiple satellite sensors. Files are in netCDF format with a spatial resolution of 1.125 x 1.125 degrees and 27 vertical pressure levels.

Use Cases

• Analyzing long-term trends in global NO2 pollution based on the 2005-2021 time series.
• Studying the vertical distribution of NO2 across 27 pressure levels from 1000 to 60 hPa.
• Validating chemical transport models using assimilated satellite observations from the MOMO-Chem framework.
• Assessing regional emissions changes by leveraging the data's simultaneous optimization of concentrations and emissions.

Strengths

• Provides a 17-year continuous time series (2005-2021) for longitudinal analysis.
• Offers 3-dimensional data with 27 vertical pressure levels, enabling study of atmospheric profiles.
• Uses a sophisticated multi-species, multi-sensor data assimilation framework (MOMO-Chem) for consistency.

Limitations

• Column names and exact data structure are not specified in the provided metadata.
• License is ambiguously listed as 'other-license-specified' without further details.
• Row counts and file sizes are unknown, limiting precise assessment of data volume.
