Reading the evidence

Sources and evidence ratings

A link identifies where a claim comes from. An organisation describing its own work is a first-party account, not independent corroboration. Where an editorial evidence rating has been given, the hub displays it.

Well corroborated

Multiple independent sources of different types support the material claim.

Corroborated

Independent support exists beyond a single source.

Single source

The account rests on one source. Read its scope and interests.

Contested

Credible accounts disagree; the disagreement matters to interpretation.

Some entries do not yet have a rating. They are labelled accordingly; absence is not evidence of corroboration.

Dates mean different things

A publication date is when a source was published. A reporting period is when an activity or result occurred. An editorial check date shows when an entry was reviewed. A link check only establishes the response received from a URL at that time.

A Checked stamp does not mean every statement on the linked page has been fact-checked again. Link status reflects the last request made, not a guarantee of current availability. Missing dates remain unknown.

Results, estimates and gaps

Reported results describe activities or outcomes in a cited account. Modelled results estimate what a scenario could produce under stated assumptions. Targets express intentions. These categories should not be treated as interchangeable.

The SUNCASA demonstration distinguishes these evidence types beside its figures. Unavailable monitoring data is shown as pending, without invented values or implied access to a partner’s internal system.

Review and corrections

Coverage and review dates vary across the hub. Updates are made through editorial curation, supported by Crawl, DAAC’s public-source engine. There is no claim here of continuous monitoring or a guaranteed monthly refresh.

The changelog describes dated revisions and their scope. A design or project-page update does not imply that the whole catalogue has been reverified.
