TRPSCRO3S6H3D: Global Tropospheric Ozone Uncertainty Reanalysis

Global 3-dimensional data provides the ensemble spread of ozone concentrations from the Tropospheric Chemical Reanalysis v2 (TCR-2) for 2005-2021. This product quantifies analysis uncertainty using JPL's MOMO-Chem data assimilation framework, which optimizes concentrations and emissions from multiple satellite sensors. Data is structured as yearly netCDF files with 6-hourly temporal resolution and 27 vertical pressure levels.

Use Cases

• Quantifying uncertainty in ozone analysis for model validation based on the ensemble spread metric.
• Studying long-term trends in tropospheric ozone variability from the 2005-2021 reanalysis period.
• Assimilating multi-sensor satellite ozone data using the described MOMO-Chem framework.
• Analyzing the vertical distribution of ozone uncertainty across 27 pressure levels from 1000 to 60 hPa.

Strengths

• Provides a 17-year continuous record from 2005 to 2021.
• Offers high vertical resolution with data across 27 distinct pressure levels.
• Derived from a sophisticated multi-species, multi-model data assimilation system (MOMO-Chem).
• Has a consistent 6-hourly temporal resolution for analyzing diurnal cycles.

Limitations

• Column names and precise data schema are not documented in the provided metadata.
• The license is ambiguously listed as 'other-license-specified' without clear terms.
• Exact file sizes and row counts are unavailable, hindering download planning.
