TOMS Meteor-3: Daily Global Ozone, UV, and Reflectivity Grids

Daily global gridded data from the Meteor-3 Total Ozone Mapping Spectrometer (TOMS) version 8 contains total column ozone, UV aerosol index, Lambertian effective surface reflectivity (Rayleigh corrected), and UV-B erythemal local noon irradiances. The data are mapped to a global grid of size 180 x 288 with a lat-long resolution of 1.00 x 1.25 degrees and are stored in the EOS Hierarchical Data Format (HDF-EOS). These data were produced by the Laboratory for Atmospheres at NASA Goddard Space Flight Center.

Use Cases

• Monitoring ozone layer depletion based on total column ozone measurements.
• Tracking aerosol events like volcanic eruptions or dust storms using the UV aerosol index.
• Analyzing surface reflectance properties for climate modeling based on Lambertian effective surface reflectivity.
• Estimating UV-B exposure risks using erythemal local noon irradiance data.
• Studying long-term atmospheric trends using daily, globally gridded time-series data.

Strengths

• Provides four distinct atmospheric measurements (ozone, aerosol index, reflectivity, UV irradiance) in a single dataset.
• Offers a consistent global spatial grid with 180 x 288 cells at a 1.00 x 1.25 degree resolution.
• Data is produced by a recognized authority, NASA Goddard Space Flight Center's Laboratory for Atmospheres.
• Dataset is available on multiple platforms (NASA Earthdata and Data.gov), indicating established use.

Limitations

• Exact temporal coverage (start and end dates) is not specified in the provided metadata.
• Column names and specific data formats within the HDF-EOS files are not detailed.
• Metadata shows a conflict for 'last updated' date between 1994-11-24 and 2026-04-09.
