Prior studies usually cover one to three cities, use kilometer-scale products, or do not release data and code. We introduce HeatCast, a Landsat-based benchmark for monthly LST forecasting across 124 U.S. cities from 2013 through June 2025. HeatCast contains 30 m monthly tiles with LST, elevation, surfacereflectance RGB, three spectral indices, broadband albedo, quality masks, and Local Climate Zone (LCZ) labels, together with a fixed tem","authors_text":"Isaac Corley, Jesus Guerrero, Leon Najafirad, Maryam Tabar, Paul Rad","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-08-07T16:08:49Z","title":"HeatCast: A Benchmark for Neighborhood-Scale LST Forecasting across 124 U.S. Cities"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2608.07640","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:b77ec38f2bcc790fb8156414b974c573d89c6504dd2fba86566827da3bdac4b0","target":"record","created_at":"2026-08-11T00:15:33Z","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":"e1e9f42d01212d08eda2949ab221d3ca9f717bc077836d85d9d89ffe0f7082e7","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-08-07T16:08:49Z","title_canon_sha256":"a1b927b4f022e0b2c5d1e0276cc884d7a5759cb95c0228bc47fc54925e323ac4"},"schema_version":"1.0","source":{"id":"2608.07640","kind":"arxiv","version":1}},"canonical_sha256":"278466bad6b3d0600b392eb27ad1ee6afe64e74b88243ea3a6d3d501ecd394f4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"278466bad6b3d0600b392eb27ad1ee6afe64e74b88243ea3a6d3d501ecd394f4","first_computed_at":"2026-08-11T00:15:33.284381Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-08-11T00:15:33.284381Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"M8R9CL9EfIxe96Fc0gYx7K57qAkBWMZTAUhArHwVY4RoSeCxveT7S4MAQxVrKdvi9rnySMhBl7XTaI8yzU5gAw==","signature_status":"signed_v1","signed_at":"2026-08-11T00:15:33.286509Z","signed_message":"canonical_sha256_bytes"},"source_id":"2608.07640","source_kind":"arxiv","source_version":1}}},"equivocations":[{"signer_id":"pith.science","event_type":"integrity_finding","target":"integrity","event_ids":["sha256:1105031ae8deee5c474c485c6175e5768069b5caed00a778d61decacc4b75bff","sha256:716e65f2f87723a78d874ceffc3495ade8eab0eec12974d692e624f48cf98299"]}],"invalid_events":[],"applied_event_ids":["sha256:b77ec38f2bcc790fb8156414b974c573d89c6504dd2fba86566827da3bdac4b0","sha256:ec5e0d328ef67fd3eec14d1b328d55b68ff3526a60400da987d28a9bf47638d3"],"state_sha256":"aed3f3920491d3d657c62851e70a9df630aa271d65318f239f62437be59cf2d4"}
