TRPSCRO32H2D: Surface Ozone Reanalysis 2005-2021

TCR-2 reanalysis uses JPL's MOMO-Chem framework to simultaneously optimize concentrations and emissions from multiple satellite sensors. This dataset provides surface ozone concentrations at a 2-hourly resolution over a 17-year period. The data is stored in netCDF files with a spatial resolution of 1.125 x 1.125 degrees.

Use Cases

• Analyzing long-term trends in surface ozone pollution based on the 2005-2021 time range
• Modeling regional ozone concentrations based on the 1.125-degree spatial grid
• Assessing emission optimization results based on the MOMO-Chem assimilation framework
• Studying diurnal ozone cycles based on the 2-hourly temporal resolution

Strengths

• Provides a 17-year continuous record (2005-2021) for longitudinal analysis
• Offers high temporal resolution with 2-hourly data points
• Utilizes a sophisticated multi-sensor, multi-constituent assimilation framework (MOMO-Chem)

Limitations

• Column names and exact data structure are not specified in the provided metadata
• Sources disagree on the last updated date (2026-04-09 vs 2021-12-31)
• The dataset size and row count are unknown
