We propose GEN2, a generative prediction-correction framework for an efficient and accurate forecast of the extreme event statistics. The prediction step is constructed as a conditional Gaussian emulator, followed by a non-Gaussian machine-learning (ML) correction step. The ML model is trained on pairs of the reference data and the emulated fields nudged to","authors_text":"Benedikt Barthel Sorensen, Mengze Wang, Themistoklis Sapsis","cross_cats":["cs.LG","nlin.CD"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.comp-ph","submitted_at":"2025-08-21T03:14:25Z","title":"GEN2: A Generative Prediction-Correction Framework for Long-time Emulations of Spatially-Resolved Climate Extremes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2508.15196","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0af4837e8ac972930fd0ae2c03ae18348d26359ab47ea0f98cc27ede77cd5357","target":"record","created_at":"2026-07-05T11:57:08Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"ae56f01bc4df3bfaad2d98f53628d55c87637f4298aa38f5e766513c955b0229","cross_cats_sorted":["cs.LG","nlin.CD"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.comp-ph","submitted_at":"2025-08-21T03:14:25Z","title_canon_sha256":"0bc0d4e3bc59c9d4dbf2462165003e5a4b847d6c641f61cc96b8f411ffb8cad3"},"schema_version":"1.0","source":{"id":"2508.15196","kind":"arxiv","version":1}},"canonical_sha256":"fc0f3a223886b99006e4ae1713b0404d2067d54f9a8639b098c5691418173816","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fc0f3a223886b99006e4ae1713b0404d2067d54f9a8639b098c5691418173816","first_computed_at":"2026-07-05T11:57:08.121962Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:57:08.121962Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0L4+6L6SO35cvUhtSz3RgMAf1MWFpdqxX+8CI250pEjBd/qX0wK3eKBGX/kpDe5zk6u4tmSOUD4D/WKkPROVCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T11:57:08.122349Z","signed_message":"canonical_sha256_bytes"},"source_id":"2508.15196","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0af4837e8ac972930fd0ae2c03ae18348d26359ab47ea0f98cc27ede77cd5357","sha256:e33f92226bd1ddcd714ffd278123ed4ae4b611677cea52af2001661daebebaa9"],"state_sha256":"8f2289aee432bb9d7d74e38d9086a2aa45ec5681ce1c68fcf4399aff0c662cdd"}
