OMPS-NPP: Daily Global Ozone Satellite Grid

OMPS-NPP L3 NM Ozone Total Column data provides daily global maps of atmospheric ozone concentrations. Measurements are derived from the Ozone Mapping and Profiling Suite Nadir-Mapper instrument aboard the Suomi-NPP satellite. The product includes UV aerosol index and reflectivity at 331 nm retrievals, gridded to a 1.0-degree resolution.

Use Cases

• Tracking global ozone hole formation and recovery based on daily total column measurements.
• Analyzing seasonal and interannual ozone variability using the 1.0-degree gridded time series.
• Correlating atmospheric aerosol load with ozone levels using the included UV aerosol index data.
• Validating atmospheric chemistry model outputs against satellite-derived ozone maps.

Strengths

• Provides daily global coverage from -90 to 90 degrees latitude.
• Offers a consistent 1.0-degree longitude by 1.0-degree latitude grid (360x180 array).
• Includes multiple derived parameters: ozone total column, UV aerosol index, and reflectivity at 331 nm.

Limitations

• Key metadata such as row count, file size, and specific license terms are inconsistently reported or missing across platforms.
• Column names and detailed data structure are not provided in the available descriptions.
• The 'last updated' date of 2026-04-09 appears to be a future date, indicating potential metadata error.
