Topic: Upgrade of the Solar tables for Suomi National Polar-orbiting Partnership (S-NPP) Ozone Mapping and Profiler Suite Nadir Profiler Sensor Data Record (OMPS NP SDR)

Date/Time Issued: July 22, 2026 1407 UTC

Product(s) or Data Impacted: V8Pro (OMPS NP) SDR and EDR (Environmental Data Records)

Date/Time Initial Impact: TBD (Late next week)

Date/Time of Expected End: N/A

Length of Outage: NA

Details/Specifics: 

Following the S-NPP Safehold Event on July 10th, the OMPS Team is utilizing the current gap in OMPS NP SDR and V8Pro EDR product availability to deploy an upgraded methodology for the biweekly solar tables. This new approach adjusts the solar irradiance spectra to simultaneously account for instrument throughput calibration variations and solar activity. Once product distribution is fully restored, these new spectra will yield more accurate radiance-to-irradiance measurement ratios.

As a result of these enhancements, users will observe small (±1%) layer-dependent variations in the V8Pro ozone profile EDRs relative to retrievals from before the event. 

This update is slated for promotion to PROD on Wednesday, July 22, 2026, and will become effective when S-NPP OMPS Nadir Profiler data availability resumes late next week.

There is no change to the file names.
