TOMSEPL3mery: UV-B Erythemal Irradiance Monthly Grid

NASA Earth Probe Total Ozone Mapping Spectrometer version 8 monthly averaged global gridded data contains UV-B erythemal local noon irradiance values. The data are mapped to a global grid of 180 x 288 cells with a lat-long resolution of 1.00 x 1.25 degrees. It is produced by the Laboratory for Atmospheres at NASA Goddard Space Flight Center.

Use Cases

• Monitoring global UV-B exposure trends based on monthly averaged irradiance values.
• Assessing ozone layer effects on surface ultraviolet radiation using mapped erythemal irradiance.
• Modeling spatial patterns of solar radiation risk using the 1 deg x 1.25 deg global grid.
• Analyzing long-term changes in atmospheric radiation from the time-series monthly data.

Strengths

• Provides a specific global spatial resolution of 1.00 x 1.25 degrees.
• Contains a defined grid size of 180 x 288 cells for consistent global coverage.
• Data originates from a recognized NASA laboratory (Code 614 at Goddard Space Flight Center).

Limitations

• Column names and data structure details are unknown across all sources.
• Sources conflict on the last updated date (2003 vs. 2026), indicating potential metadata inconsistency.
• The dataset is stored in ASCII format, which may require conversion for modern analysis tools.
