TROPESS TCR-2: Global 3D Sulfur Dioxide Concentrations

The TROPESS Chemical Reanalysis SO2 6-Hourly 3-dimensional Product provides vertical concentrations of sulfur dioxide from the Tropospheric Chemical Reanalysis v2 (TCR-2). TCR-2 uses JPL's MOMO-Chem data assimilation framework to simultaneously optimize concentrations and emissions from multiple satellite sensors for the period 2005-2021. Data files are in netCDF format, containing yearly data at 6-hourly resolution with a spatial grid of 1.125 x 1.125 degrees across 27 pressure levels.

Use Cases

• Analyzing global sulfur dioxide transport patterns based on 3-dimensional concentration fields.
• Studying temporal trends in SO2 emissions from 2005 to 2021 using the 6-hourly reanalysis.
• Validating atmospheric chemistry models against assimilated satellite observations from the MOMO-Chem framework.
• Investigating vertical distribution of SO2 across 27 pressure levels between 1000 and 60 hPa.

Strengths

• Provides a 17-year continuous time series (2005-2021) for longitudinal analysis.
• Offers high vertical resolution with data across 27 distinct pressure levels.
• Utilizes a sophisticated multi-species, multi-model assimilation framework (MOMO-Chem) from JPL.

Limitations

• Column names and specific variable metadata are not provided in the available descriptions.
• The spatial resolution of 1.125 degrees is coarse for localized regional studies.
• Platform metadata for size, row count, and author is incomplete or conflicting.
