Evidence & methods

Make the scope visible.

The library is a discovery resource. The tools are explicit calculations. The experimental protocol is a proposal. Each has a different evidential role.

What is in the index?

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.

Thirty-three topic-specific title searches returned up to 45 journal-article records each. Keyword screening was followed by record-by-record title screening of the final selection. Narrow categories were not filled with unrelated records to meet a uniform quota.

Edition 03 contains 268 records: 267 journal records with DOIs and 1 arXiv preprint. There are 18 scoped evidence notes and 250 metadata-only records. The publication cutoff is 11 October 2026. Patent resources are listed separately and are not counted as papers.

Two review statuses

Metadata 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.

Scoped evidence note

The primary material identified in reviewSources was consulted to check the specific, limited claim described in notes. reviewScope states whether this was full text, selected sections or an abstract/result check. The source checks are AI-assisted under the founder’s direction; this is not represented as named expert peer review, independent replication or a blanket endorsement.

Metadata provenance

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. Edition 03 adds a source-checked West Texas journal article; its original PDF corrects malformed deposited author metadata, with the date conventions retained explicitly.

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.

Dates and precision

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.

Research and review labels

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.

Preprints and versions

Preprints retain the repository identifier, version, posting date and explicit preprint status. A weatherhill evidence note describes our reading scope; it does not imply peer review. A later journal version is linked rather than silently substituted. The initial Crossref journal search remains recorded below.

Open-access links

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.

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. The added West Texas paper was checked against its original PDF, publisher page and Crossref record, with record-specific corrections disclosed.

Coverage 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.

Search and access

All catalog records remain available through the library, static index, reading lists and exports. Metadata-only detail pages carry a noindex instruction and are omitted from the sitemap. Scoped evidence notes and the main research resources remain eligible for indexing. This is a choice about what the site presents to search engines, not a claim that a larger catalog necessarily harms rankings.

Editorial responsibility

Weatherhill’s source checks, notes, code and website are developed with AI assistance under the founder’s direction. A scoped note identifies the material consulted and the limit of the check. It is not represented as a named scientist’s peer review, an institutional endorsement or independent replication. Corrections should identify the exact source and statement.

What the calculators do

The tools expose a stated model, its input units and its limitations. Scientific examples are synthetic unless you load your own dataset. A curve drawn by the browser is a calculation, not an experimental observation.

The paired-analysis tool uses independent-day means and a Student t interval, with systematic bias expanded separately. The sample planner uses the protocol’s 80% one-sided upper bound on pilot standard deviation and a noncentral-t power calculation, with a 24–48 valid-day confirmation range. Its default is 35 confirmation days under hypothetical pilot inputs; six pilot days, qualification, earlier discovery and failed attempts are separate. The model is exact under its stated independent, normally distributed day-effect assumption; its power is not a guarantee of product success.

Versioned experimental decisions

WX-FOG-001 v0.2 sets out the proposed qualification, discovery and confirmation sequence. Its design choices have not been demonstrated by weatherhill. Changes to a protocol should be dated, justified and fixed before the data they govern are observed.

Images and product status

FogLab images are supplied concept artwork. The website’s controls and calculations are functional; the pictured apparatus is not presented as built, tested, certified or available for sale.
