TROPESS TCR-2: Global Formaldehyde Concentrations 2005-2021

2005-2021 monthly formaldehyde concentrations are provided by the Tropospheric Chemical Reanalysis v2 (TCR-2), using JPL's MOMO-Chem framework to assimilate data from multiple satellite sensors. The product offers 3-dimensional data at 27 pressure levels between 1000 and 60 hPa, with a spatial resolution of 1.125 x 1.125 degrees. The reanalysis simultaneously optimizes both atmospheric concentrations and emissions for multiple chemical species.

Use Cases

• Analyzing long-term trends in formaldehyde concentrations based on the 2005-2021 monthly time series.
• Studying vertical distribution of formaldehyde in the troposphere using the 27 pressure level data.
• Assessing regional formaldehyde emissions and transport patterns using the 1.125-degree gridded data.
• Validating chemical transport models with assimilated concentration and emission estimates from the MOMO-Chem framework.

Strengths

• Provides a 17-year continuous time series (2005-2021) for longitudinal analysis.
• Offers detailed vertical resolution with data at 27 distinct pressure levels.
• Uses a sophisticated multi-species assimilation framework (MOMO-Chem) that optimizes both concentrations and emissions.

Limitations

• Specific column names and variable details within the NetCDF files are not provided in the metadata.
• The dataset's size and row count are unspecified across all sources.
• License information is inconsistently reported as 'other-license-specified' or 'None'.
