MSO3L3zm5: Global Ozone Profiles and Total Columns from Merged Satellite Data, 1970-2013

Global monthly zonal mean ozone data from 1970 to 2013, covering latitudes from -80.0 to 80.0 degrees in 5.0-degree zones. The dataset contains profile layer and total column ozone estimates from multiple Nimbus and NOAA satellite instruments, processed with the v8.6 SBUV algorithm. It was produced by the National Aeronautics and Space Administration and is stored in a single 0.4 MB HDF5 file.

Use Cases

• Modeling long-term stratospheric ozone trends based on the 43-year time series.
• Analyzing latitudinal ozone distribution based on the 5.0-degree zonal mean data.
• Comparing ozone retrieval algorithms based on the v8.6 SBUV methodology described.
• Studying satellite instrument calibration and continuity across multiple missions.

Strengths

• Covers a 43-year time period from May 1970 through July 2013.
• Provides global coverage from -80.0 to 80.0 degrees latitude.
• Integrates data from multiple satellite missions (Nimbus-4 BUV through NOAA-18 SBUV/2).
• Uses a refined v8.6 algorithm with updated cross-sections and climatology.

Limitations

• Data coverage contains gaps, especially between 1973-1977 and 1976-1978.
• Row count and specific column-level documentation are unknown.
• Last updated metadata is from 2026-03-13; data freshness should be verified.
