OML1BRUZ: Aura Satellite UV Zoom-in Spectral Radiance Data

Global satellite observations from the Aura Ozone Monitoring Instrument (OMI) provide geolocated Earthshine UV radiance measurements in zoom-in mode. The dataset contains spectral radiances from 264 to 383 nm, with approximately 14 orbital data files (~210 MB each) generated per day, though the zoom-in product is only available about once a month. Data is stored in netCDF format and covers the daylit portion of orbits.

Use Cases

• Monitoring atmospheric composition and trace gases based on UV spectral radiance measurements.
• Analyzing spatial distribution of aerosols and clouds using geolocated, high-resolution ground pixel data (13 km x 12 km at nadir).
• Calibrating and validating radiative transfer models with Earth view spectral radiances from 264 to 383 nm.
• Studying long-term UV radiation trends from a consistent, orbital satellite time series.

Strengths

• Provides high spatial resolution with 60 ground pixels across a ~750 km swath for Band 2 and 30 pixels across a ~2600 km swath for Band 1.
• Contains detailed spectral information with 557 channels in the 307-383 nm range and 159 channels in the 264-311 nm range.
• Data is stored in the standardized, self-describing netCDF format, facilitating scientific analysis.

Limitations

• Key metadata such as column names, row counts, and exact temporal coverage are not provided in the available sources.
• The zoom-in mode product is only available approximately once a month, limiting temporal frequency for specific analyses.
• License is listed as 'other-license-specified' without explicit terms, requiring user verification.
