TROPESS TCR-2: Global Surface Pressure Reanalysis

TROPESS Chemical Reanalysis Surface Pressure 2-Hourly 2-dimensional Product provides global surface pressure values from the Tropospheric Chemical Reanalysis v2 (TCR-2). The dataset spans 2005-2021, with a 2-hourly temporal resolution and a spatial grid of 1.125 x 1.125 degrees. It is generated using JPL's MOMO-Chem data assimilation framework, which optimizes concentrations and emissions from multiple satellite sensors.

Use Cases

• Analyzing global atmospheric pressure patterns based on the 2-hourly time series.
• Validating meteorological inputs for chemical transport models using assimilated satellite data.
• Studying long-term trends in surface pressure from 2005 to 2021.
• Incorporating reanalysis data into climate studies due to the 1.125-degree spatial resolution.

Strengths

• Provides a 17-year continuous time series from 2005 to 2021.
• Offers high temporal resolution with 2-hourly data points.
• Utilizes a sophisticated data assimilation framework (MOMO-Chem) integrating multiple satellite sensors.

Limitations

• Column names and exact data structure are not documented.
• Metadata for size, row count, and author is missing across platforms.
• There is a conflict in the 'last updated' metadata between 2026-04-09 and 2021-12-31.
