SBUV2N14L2: Daily Ozone Profile and Total Column Data from NOAA-14

NOAA-14 satellite data from 1995 to 2006 provides daily ozone nadir profiles and total column measurements using the v8.6 SBUV algorithm. This algorithm incorporates Brion-Daumont-Malicet ozone cross-sections and an OMI-derived cloud-height climatology for retrieval. The daily HDF5 files served as the direct input for generating monthly zonal mean ozone products.

Use Cases

• Analyzing long-term stratospheric ozone trends based on daily nadir profile data from 1995-2006.
• Validating newer satellite ozone retrievals using the v8.6 algorithm's inter-instrument calibration methodology.
• Studying the impact of cloud-height climatology on ozone profile estimates derived from SBUV measurements.
• Creating aggregated monthly zonal mean datasets from the foundational daily Level-2 files.

Strengths

• Provides a continuous 11.5-year time series from March 1995 through September 2006.
• Uses a specific, documented retrieval algorithm (v8.6 SBUV) with named cross-sections and climatologies.
• Data is cross-platform available on NASA EarthData and Data.gov, indicating established use.

Limitations

• Column names and detailed schema are not provided in any source description.
• Conflicting 'last updated' metadata: one source lists 2026-04 09, another lists 2006-09-28.
• File sizes (1-5 MB) suggest data volume, but total row count and dataset size are unknown.
