OML1BRVZ: Aura OMI VIS Zoom-in Geolocated Earthshine Radiances

The OMI/Aura Level 1B VIS Zoom-in Geolocated Earthshine Radiances V004 dataset contains spectral radiance measurements from the daylit portion of satellite orbits, produced approximately once per month. It provides geolocated Earth view spectral radiances from the VIS detectors in the 349 to 504 nm wavelength range, with each orbit file covering a swath width of roughly 750 km. Data is stored in netCDF format, with each of the approximately 14 daily orbital files being about 240 MB in size.

Use Cases

• Analyzing high-resolution spectral signatures of Earth's surface and atmosphere based on 751 channels in the 349-504 nm band.
• Monitoring spatial radiance patterns across a ~750 km swath using 60 ground pixels (13 km x 12 km at nadir) per observation.
• Calibrating atmospheric models with geolocated, time-series spectral radiance data from the Aura satellite's zoom-in measurement mode.

Strengths

• Provides high spectral resolution with 751 channels in Band 3 (349-504 nm).
• Offers detailed spatial observation with 60 ground pixels across a ~750 km swath.
• Data is stored in the standardized, self-describing netCDF format.

Limitations

• Key metadata such as column names, row counts, and exact temporal coverage are unavailable across all sources.
• The dataset's availability is limited to approximately once per month.
• License information is inconsistently reported as 'other-license-specified' or null.
