OMUVBd: Daily Global Surface UVB Irradiance and Erythemal Dose

Global daily gridded data provides erythemally weighted ultraviolet (UVB) dose and dose rate at local solar noon. Measurements are derived from the Aura-OMI satellite at a 1.0x1.0 degree spatial resolution. Each file contains data from the sunlit portion of the globe and is stored in the HDF-EOS5 format.

Use Cases

• Tracking global UV exposure trends based on daily erythemal dose grids.
• Modeling skin cancer risk factors using surface UVB irradiance data.
• Validating atmospheric chemistry models with satellite-derived spectral surface measurements.
• Assessing solar radiation for agricultural or environmental studies using gridded noon-time dose rates.

Strengths

• Data has a global spatial scope, covering the entire sunlit portion of Earth.
• Provides daily temporal resolution for tracking short-term UV variations.
• Produced by a authoritative source, the National Aeronautics and Space Administration.

Limitations

• Key metadata such as row count, column names, and exact time range are unavailable.
• Spatial resolution of 1.0x1.0 degrees may be too coarse for localized studies.
• License is ambiguously listed as 'other-license-specified' without clear terms.
