TROPESS Chemical Reanalysis: Sulfate Aerosol Concentrations

Global sulfate aerosol concentrations are provided from 2005 to 2021, derived from the Tropospheric Chemical Reanalysis v2 (TCR-2). The dataset uses JPL's MOMO-Chem assimilation framework to optimize concentrations and emissions from multiple satellite sensors. Data are structured as monthly 3-dimensional grids at 27 pressure levels between 1000 and 60 hPa, with a spatial resolution of 1.125 x 1.125 degrees.

Use Cases

• Analyzing long-term trends in sulfate aerosol pollution based on the 2005-2021 time series.
• Modeling vertical distribution of aerosols for atmospheric studies based on the 27 pressure levels.
• Assessing global sulfate emissions and transport patterns based on the 1.125-degree spatial grid.
• Validating chemical transport models using assimilated satellite observations from the TCR-2 framework.

Strengths

• Provides a 17-year continuous time series (2005-2021) for longitudinal analysis.
• Offers detailed vertical profiling with data at 27 distinct pressure levels.
• Utilizes a sophisticated multi-species, multi-model assimilation framework (MOMO-Chem) for data consistency.

Limitations

• Specific column names and data volume (size/rows) are not documented across all platforms.
• The license is ambiguously listed as 'other-license-specified' without further detail.
• Data freshness is unclear as the last update metadata is inconsistent across sources.
