  "source": "The initial journal catalog uses publisher-deposited bibliographic records retrieved through the public Crossref REST API. Edition 02 also includes an explicitly versioned preprint verified against the original arXiv entry. Scoped notes link to the primary material actually consulted.",
  "selection": "Thirty-three topic-specific title searches returned up to 45 journal-article records each. Keyword screening was followed by manual title screening of the final selection. Narrow categories were not filled with unrelated records to meet a uniform quota.",
  "scope": "Fog microphysics and visibility, electrical droplet processes, fog collection, atmospheric electricity, cloud seeding, aerosol activation, lightning and atmospheric lasers, measurement, cloud remote sensing, plume recovery and atmospheric modeling.",
  "statusDefinitions": {
    "indexed": "Bibliographic fields were verified against a primary metadata response and the title was screened for topical relevance. Article contents and scientific conclusions have not been reviewed by Weatherhill.",
    "reviewed": "The research team read the primary material identified in reviewSources and checked the specific, limited claim described in notes. reviewScope states whether this was full text, selected sections, or an abstract/result check. This is not independent replication or a blanket endorsement."
  },
  "deduplication": "Case-normalized DOI plus normalized title for journal records; repository and identifier plus version for preprints. Stable local IDs are unique. Related preprint and journal versions should be linked, with publication status preserved.",
  "dateRules": "Dates are taken from publisher-deposited published-online, published-print, published and issued fields. The earliest eligible deposited date is retained. Precision is preserved as year, month or day. Partial date intervals must fall wholly on or before 2026-10-11; no date is inferred from the DOI string. Crossref dates can reflect digital republication rather than first historical publication.",
  "kindRules": "An editorial navigation label: titles explicitly identifying a review, overview, survey or state-of-the-art paper are labeled review; other selected journal-article metadata records are labeled research. These labels are not a verified classification of study design. evidenceType is supplied only for reviewed anchors.",
  "openAccessRules": "openAccessUrl is supplied only for a primary repository or journal page that was accessed as openly available. Absence does not imply a paywall. Journal records link to their DOIs; the preprint links to its versioned repository record.",
  "validation": "The original 266 journal records were matched to retained Crossref responses for bibliographic fields. The added arXiv preprint was checked against its original repository metadata and v1 text. Stable IDs and nonempty DOIs are unique. A scoped evidence note does not establish peer review.",
  "limits": [
    "This is a curated discovery index, not a systematic review, exhaustive bibliography, citation ranking or quality assessment.",
    "Search-engine ranking, English-language queries, DOI registration and publisher metadata availability influence coverage. A relevant paper may be absent.",
    "The indexed status does not establish that an intervention works. Papers may report null results, models, laboratory work, or disputed interpretations.",
    "Bulk metadata records were not independently audited against complete publisher full texts; deposited metadata can contain errors.",
    "No copyrighted article full texts or abstracts are included. Only bibliographic metadata, links and original, narrowly scoped anchor notes are stored."
