IBM System Storage Ideas Portal


This portal is to open public enhancement requests against IBM System Storage products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).

Contrail Climate Record Retention

PROBLEM: Contrail science depends on long baselines: Lee et al. 2021 assessed 2000–2018; Teoh et al. 2024 compared 2019–2021 against 2018; Travis et al. 2002 needed 30 years of temperature data (1971–2000) to recognize a three-day anomaly. Yet satellite contrail detections, flight-track archives and humidity reanalyses are kept under different retention rules by different owners, and old records are deleted before anyone knows they are the baseline for the next study.

SOLUTION: A contrail climate record retention rule: contrail detections, flight tracks and humidity fields retained together for a stated minimum period with a stated owner — so the baseline for the next decade's contrail science is not deleted in this decade's storage cleanup.

EVIDENCE BASIS: DOCUMENTED — Lee et al. 2021 (2000–2018); Teoh et al. 2024 (2019–2021); Travis et al. 2002 (1971–2000 baseline, ~4,000 stations). Sources: Lee et al. 2021; Teoh et al. 2024; Nature 418, 601.
