Using the authors' own FOSCAT software (specifically following Jean-Marc Delouis's IGARSS 2024 Pangeo tutorial workflow), scattering-transform synthesis fills cloud gaps in Copernicus Marine sea surface temperature observations to within 1 K of an operational gap-free analysis product, and outperforms a standard spherical-harmonic interpolation baseline by approximately an order of magnitude. The framework's applicability to oceanographic Earth observation is therefore concretely demonstrated, not only argued. https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/delouis-2022-sst-replication-outcome https://w3id.org/sciencelive/o/terms/hasConfidenceLevel https://w3id.org/sciencelive/o/terms/HighConfidence https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/delouis-2022-sst-replication-outcome https://w3id.org/sciencelive/o/terms/hasEvidenceDescription Single-day experiment on Copernicus Marine SST for 2026-04-01. Inputs: L3S PMW (cmems_obs-sst_glo_phy_l3s_pmw_P1D-m) with cloud gaps, L4 analysis (cmems_obs-sst_glo_phy-temp_nrt_P1D-m) as gap-free reference, both at 0.25° native resolution and downgraded to HEALPix nside=32 (12,288 cells). FOSCAT scattering synthesis: NORIENT=4, KERNELSZ=3, 300 L-BFGS iterations, ~139 seconds on CPU (Apple M1 Pro). Validation against L4 in cloudy regions only:\n\n- Spherical-harmonic baseline RMSE: 11.46 K\n- FOSCAT RMSE: 0.989 K\n- Improvement: 91.4%\n\nFull results JSON archived at Zenodo 10.5281/zenodo.19686691. https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/delouis-2022-sst-replication-outcome https://w3id.org/sciencelive/o/terms/hasLimitationsDescription Three caveats limit the strength of the conclusion: (1) Single-date evaluation. Only one day (2026-04-01) of L3S/L4 SST was tested; cloud distribution, ocean regimes, and the gap pattern vary across days and seasons, so a multi-day study would strengthen the result. (2) Lower-than-paper resolution. nside=32 (~6° angular resolution) was used for CPU runtime; the original paper operates at nside=256, and the WGS84 follow-up study (fiesta-scattering-sst-healpix-geo) shows the framework's behaviour can change at higher resolution. (3) L4 as ground truth. The 0.989 K RMSE is computed against the L4 operational analysis product, not against in-situ measurements; L4 itself is an interpolation of observations and may have systematic biases that propagate into the apparent 'truth'. https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/delouis-2022-sst-replication-outcome https://w3id.org/sciencelive/o/terms/hasOutcomeRepository https://doi.org/10.5281/zenodo.19707888 https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/delouis-2022-sst-replication-outcome https://w3id.org/sciencelive/o/terms/hasValidationStatus https://w3id.org/sciencelive/o/terms/Validated https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/delouis-2022-sst-replication-outcome https://w3id.org/sciencelive/o/terms/isOutcomeOf https://w3id.org/sciencelive/np/RA45t1bdfz6Jr40G9dDqrWAF4i7-DT3HQNOSheRWjcuho/delouis-2022-sst-replication-study https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/provenance https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/assertion http://www.w3.org/ns/prov#wasAttributedTo https://orcid.org/0000-0002-1784-2920 https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/pubinfo https://orcid.org/0000-0002-1784-2920 http://xmlns.com/foaf/0.1/name Anne Fouilloux https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40 http://purl.org/dc/terms/created 2026-04-26T17:49:33.886Z https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40 http://purl.org/dc/terms/creator https://orcid.org/0000-0002-1784-2920 https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40 http://purl.org/dc/terms/license https://creativecommons.org/licenses/by/4.0/ https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40 http://purl.org/nanopub/x/introduces https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/delouis-2022-sst-replication-outcome https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40 http://purl.org/nanopub/x/wasCreatedAt https://platform.sciencelive4all.org https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40 http://www.w3.org/2000/01/rdf-schema#label NP created using Declaring a replication study outcome according to FORRT https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40 https://w3id.org/np/o/ntemplate/wasCreatedFromTemplate https://w3id.org/np/RA2zljn0Nw9SadppOyxZoh-_Rxosslrq-vYG-p9SttnJE https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/sig http://purl.org/nanopub/x/hasPublicKey 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 https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/sig http://purl.org/nanopub/x/hasSignature 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 https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40 https://w3id.org/sciencelive/np/RAK2ynlqgA3L_YVbEo-cVoXZ7T63q4eCFZqf9CPWWNc40/sig http://purl.org/nanopub/x/signedBy https://orcid.org/0000-0002-1784-2920
