Ozone Monitoring Instrument Atmospheric Composition Data

Satellite observations from the Ozone Monitoring Instrument (OMI) provide global mapping of ozone columns, profiles, and key air quality components. The dataset includes measurements of NO2, SO2, BrO, HCHO, aerosols, cloud properties, and UV-B radiation. Data is processed by NASA and ESA into four levels, from raw sensor counts to time-composited global grids.

Use Cases

• Analyze global trends in NO2 and SO2 columns to assess regional air pollution changes over time.
• Distinguish aerosol types like smoke, dust, and sulfates using aerosol absorption optical depth measurements.
• Map daily or monthly UV-B radiation distribution and cloud coverage from Level 3 global grid products.
• Calibrate atmospheric models with geo-located orbital swath data for ozone profiles at 13 km x 48 km resolution.

Strengths

• Measures multiple atmospheric components: ozone, NO2, SO2, BrO, HCHO, aerosols, clouds, and UV-B.
• Provides data at four processing levels from raw sensor counts to globally gridded composites.
• Offers fine spatial resolution for ozone mapping at 13 km x 24 km.

Limitations

• Specific row count, file size, and temporal coverage range are not provided in the input.
• Data availability and completeness may vary by processing level (Level 0 to Level 3).
• License terms for use and redistribution are unknown.
