TRPSCRSO2M3D: Monthly 3D Sulfur Dioxide Concentrations, 2005-2021

2005-2021 monthly vertical concentrations of sulfur dioxide (SO2) are provided by the Tropospheric Chemical Reanalysis v2 (TCR-2). The data uses JPL's MOMO-Chem assimilation framework to optimize concentrations and emissions from multiple satellite sensors. Each file contains a year of data at 1.125 x 1.125 degree spatial resolution across 27 pressure levels.

Use Cases

• Analyzing long-term trends in global SO2 pollution based on the 2005-2021 time series.
• Validating atmospheric chemistry models using the 3D, pressure-level concentration data.
• Studying volcanic or anthropogenic emission events using the assimilated satellite observations.
• Investigating seasonal and spatial patterns of tropospheric SO2 at a 1.125-degree resolution.

Strengths

• Provides a 17-year continuous record (2005-2021) for longitudinal analysis.
• Offers 3-dimensional data with 27 vertical pressure levels between 1000 and 60 hPa.
• Uses a sophisticated multi-species data assimilation framework (MOMO-Chem) from JPL.
• Has a consistent monthly temporal resolution and 1.125 x 1.125 degree global spatial grid.

Limitations

• Column names and specific variable metadata are not provided in the available descriptions.
• The license is ambiguously listed as 'other-license-specified' without clear terms.
• Data freshness is unclear; the last metadata update is listed as 2026, which may be an error.
