SBUV2N09L2: Daily Ozone Profiles and Total Columns from NOAA-9

From February 1985 through January 1998, this dataset provides daily ozone nadir profile and total column measurements from the NOAA-9 satellite's Solar Backscattered Ultraviolet (SBUV) instrument. The data are generated using the v8.6 SBUV algorithm, which incorporates specific ozone cross-sections and cloud-height climatologies. These Level-2 daily files serve as the input for creating monthly zonal mean ozone products.

Use Cases

• Analyzing long-term ozone layer trends based on daily nadir profile retrievals.
• Validating atmospheric chemistry models using satellite-derived total column ozone data.
• Studying interannual ozone variability from a 13-year satellite record.
• Assessing algorithm performance for the v8.6 SBUV retrieval method.

Strengths

• Provides a continuous 13-year time series from 1985 to 1998.
• Uses a specific, documented algorithm (v8.6) with named cross-sections and climatologies.
• Data is cross-platform available, indicating established scientific use.

Limitations

• Column names and detailed schema are not provided in the available metadata.
• Conflicting 'last updated' dates (1998 vs. 2026) suggest metadata management issues.
• Data format (HDF5) and lack of column details may require specialized tools for access and analysis.
