TROPESS TCR-2: OH Radical Concentrations 2005-2021

TROPESS Chemical Reanalysis OH 6-Hourly 3-dimensional Product provides vertical concentrations of the hydroxyl radical (OH) from the Tropospheric Chemical Reanalysis v2 (TCR-2). TCR-2 uses JPL's MOMO-Chem data assimilation framework to optimize concentrations and emissions from multiple satellite sensors for the period 2005-2021. Data files are netCDF4 format, containing yearly data at 6-hourly resolution with a spatial grid of 1.125° and 27 pressure levels.

Use Cases

• Analyzing hydroxyl radical concentration trends over time based on the 6-hourly temporal resolution from 2005-2021
• Studying vertical distribution of OH in the troposphere based on the 27 pressure levels between 1000 and 60 hPa
• Assessing global spatial patterns of atmospheric chemistry based on the 1.125 x 1.125 degree latitude-longitude grid
• Validating chemical transport models using reanalysis data from the JPL MOMO-Chem assimilation framework

Strengths

• Provides a 17-year continuous time series (2005-2021) for long-term trend analysis
• Offers high temporal resolution (6-hourly) and detailed vertical profiling (27 pressure levels)
• Data is produced using a sophisticated multi-species assimilation framework (JPL MOMO-Chem)

Limitations

• Column names and specific variable metadata are not provided in the available descriptions
• License is ambiguously described as 'other-license-specified' without explicit terms
• Dataset size and row counts are unknown across all sources
