TROPESS TCR-2: Ammonium Aerosol Vertical Concentrations

TROPESS Chemical Reanalysis v2 (TCR-2) provides a 3-dimensional dataset of ammonium aerosol vertical concentrations. It covers the period 2005-2021 with 6-hourly resolution, generated using JPL's MOMO-Chem framework to assimilate data from multiple satellite sensors. The product has a spatial resolution of 1.125 degrees and 27 vertical pressure levels.

Use Cases

• Analyzing global ammonium aerosol transport patterns based on 3-dimensional concentration fields.
• Assessing long-term trends in ammonium aerosol pollution from the 2005-2021 time series.
• Validating chemical transport models using assimilated satellite observations.
• Studying vertical distribution of aerosols across 27 pressure levels from 1000 to 60 hPa.
• Investigating emissions optimization results from the MOMO-Chem data assimilation framework.

Strengths

• Provides a 17-year continuous time series (2005-2021) for longitudinal analysis.
• Offers high temporal resolution with 6-hourly data points.
• Includes detailed vertical structure with data at 27 distinct pressure levels.
• Utilizes a sophisticated assimilation framework (MOMO-Chem) combining multiple satellite sensors.

Limitations

• Column names and specific variable metadata are not provided in the available descriptions.
• The dataset's size and row count are unknown, limiting assessment of data volume.
• License information is inconsistently reported as 'other-license-specified' or 'None' across sources.
