TRPSCRO3M3D: Global Tropospheric Ozone Reanalysis 2005-2021

2005-2021 monthly 3D ozone concentrations from the Tropospheric Chemical Reanalysis v2 (TCR-2). The dataset uses JPL's MOMO-Chem data assimilation framework to optimize concentrations and emissions from multiple satellite sensors. Data is provided in netCDF4 files with a spatial resolution of 1.125 x 1.125 degrees across 27 pressure levels.

Use Cases

• Analyzing long-term trends in tropospheric ozone concentrations based on the 2005-2021 monthly time series.
• Validating atmospheric chemistry models using the assimilated 3D concentration fields from the MOMO-Chem framework.
• Studying the vertical distribution of ozone across the 27 pressure levels between 1000 and 60 hPa.
• Investigating regional ozone pollution and transport patterns using the 1.125-degree global grid.

Strengths

• Provides a 17-year (2005-2021) consistent reanalysis time series for long-term trend analysis.
• Offers 3-dimensional data with 27 vertical pressure levels, enabling analysis of ozone profiles.
• Uses a sophisticated multi-species, multi-sensor data assimilation framework (MOMO-Chem) from JPL.
• Has a documented principal investigator (Kazuyuki Miyazaki) and originates from NASA.

Limitations

• Column names and detailed variable metadata are not provided in the source descriptions.
• License information is inconsistent ('other-license-specified' on datagov vs. 'None' on nasa_earthdata).
• Dataset size and row counts are uniformly listed as unknown or 'None' across all platforms.
