Global GEOS-Chem simulations at 2° × 2.5° resolution were used to generate O3 concentrations constrained by OMI NO2 observations from the NASA standard product for 2006–2016. The ozone simulations were driven by NOx emissions from a referenced source. The dataset was authored by Zhen Qu and last updated in June 2026.
Use Cases
- Modeling global tropospheric ozone distribution based on satellite-constrained simulations.
- Analyzing decadal trends in atmospheric ozone concentrations based on the 2006-2016 time series.
- Validating regional air quality models against a global posterior estimate based on OMI NO2 data.
- Studying the impact of NOx emissions on ozone levels based on the referenced emission driver.
Strengths
- Covers a continuous 11-year period from 2006 to 2016.
- Provides global coverage at a 2° × 2.5° spatial resolution.
- Integrates observations from the NASA OMI NO2 standard product.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
