SBUV2N19L2: Daily Ozone Nadir Profiles and Total Columns from NOAA-19

SBUV2N19L2 provides daily ozone nadir profile and total column data retrieved from NOAA-19 satellite measurements using the v8.6 Solar Backscattered Ultraviolet (SBUV) algorithm. The algorithm incorporates Brion-Daumont-Malicet ozone cross sections, an OMI-derived cloud-height climatology, a revised a priori ozone climatology, and inter-instrument calibration. This Level-2 product serves as the direct input for generating monthly zonal mean ozone data.

Use Cases

• Monitoring daily stratospheric ozone profiles based on nadir satellite retrievals.
• Analyzing ozone column trends over the 2009-2013 period for specific geographic regions.
• Validating other satellite or model-based ozone data using the v8.6 algorithm's cross-sections and climatology.
• Providing input data for generating higher-level, aggregated products like monthly zonal means.

Strengths

• Data is produced by a specific, documented algorithm (v8.6 SBUV) using multiple calibrated inputs.
• Covers a defined multi-year time range from February 2009 through July 2013.
• Available on multiple authoritative platforms (NASA EarthData, Data.gov), indicating established provenance.

Limitations

• Column names and detailed schema are not provided in the available metadata.
• The last updated date conflicts between sources (2013-08-01 and 2026-04 09), creating uncertainty about metadata maintenance.
• Data collection ended in July 2013, limiting analysis to historical periods.
