TRPSCRPSM2D: Global Surface Pressure from Tropospheric Chemical Reanalysis

Global data provides monthly surface pressure values from 2005 to 2021, generated by the Tropospheric Chemical Reanalysis version 2 (TCR-2). This product uses JPL's MOMO-Chem data assimilation framework to optimize atmospheric concentrations and emissions from multiple satellite sensors. Files are in netCDF4 format with a spatial resolution of 1.125 x 1.125 degrees and contain one year of data per file.

Use Cases

• Validating and initializing climate models based on assimilated surface pressure fields.
• Analyzing long-term trends in surface pressure as part of broader atmospheric studies.
• Studying tropospheric chemistry-meteorology interactions using a consistent reanalysis framework.

Strengths

• Covers a 17-year time range from 2005 to 2021, providing a long-term record.
• Uses a sophisticated multi-species, multi-sensor data assimilation framework (MOMO-Chem) for internal consistency.
• Has a defined spatial resolution of 1.125 x 1.125 degrees and monthly temporal resolution.

Limitations

• Key metadata such as row count, file size, and specific column/variable names are not provided in the sources.
• The license is ambiguously listed as 'other-license-specified' without further detail.
• Data freshness is unclear; the last updated date (2026-04-09) appears to be a future metadata timestamp.
