TRPSCRT6H3D: Tropospheric Temperature Reanalysis 2005-2021

TROPESS Chemical Reanalysis Temperature 6-Hourly 3-dimensional Product V1 (TRPSCRT6H3D) provides a global, 3D atmospheric temperature field from the Tropospheric Chemical Reanalysis v2 (TCR-2). The dataset is produced using JPL's MOMO-Chem data assimilation framework, which integrates observations from multiple satellite sensors. It offers a 17-year record at 6-hourly intervals on a 1.125-degree grid across 27 vertical pressure levels.

Use Cases

• Validating and improving global climate model temperature profiles based on the assimilated satellite observations.
• Analyzing long-term temperature trends in the troposphere from 2005 to 2021.
• Providing meteorological input fields for atmospheric chemistry transport models using the 3D, 6-hourly data.
• Studying vertical temperature structure and variability across 27 pressure levels between 1000 and 60 hPa.

Strengths

• Provides a 17-year continuous record (2005-2021) for longitudinal climate studies.
• Offers high temporal resolution (6-hourly) and 3D spatial structure across 27 vertical levels.
• Uses a sophisticated multi-species, multi-sensor data assimilation framework (JPL MOMO-Chem) to optimize the field.

Limitations

• Specific column names and data volume details are not provided in the available metadata.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
• Data freshness is unclear; the last metadata update is listed as 2026, which may be a placeholder.
