NASA GEOS-CF Global Atmospheric Composition Forecast

GEOS-CF provides global, near-real-time forecasts of atmospheric composition at a 25 km resolution. The system integrates NASA's GEOS weather model with the GEOS-Chem chemistry module to analyze pollutants like ozone, carbon monoxide, nitrogen oxides, and PM2.5. It is produced by the National Aeronautics and Space Administration (NASA).

Use Cases

• Analyzing global tropospheric ozone levels using the ozone column data.
• Tracking near-real-time sources and transport of fine particulate matter (PM2.5).
• Studying atmospheric chemistry interactions between nitrogen oxides and sulfur dioxide.
• Investigating correlations between surface air temperature and pollutant concentrations.
• Modeling global carbon monoxide distribution from combustion and natural sources.

Strengths

• Provides global coverage with a high horizontal resolution of 0.25 degrees (~25 km).
• Integrates a state-of-the-science chemistry module (GEOS-Chem) with a proven weather forecasting system.
• Offers near-real-time forecasts for a wide range of chemical species, supporting timely analysis.

Limitations

• Specific row counts, total dataset size, and detailed column names are not provided across any source.
• The license is ambiguously listed as 'other-license-specified' without clear terms.
• The last update date (2026-03-13) appears to be a future date, indicating a potential metadata error.
