Weather context Bound the information collection and preserve its distinct information kinds.
Collection identity
A proposed weather aggregate identifies a bounded collection of atmospheric assertions, not a station, the atmosphere itself or a single storm. Members retain independent identities; empty declared coverage is not evidence of fair weather.

- Which master identifier and revision identify this weather collection? identity
- What place and time window bound the collection membership? spatial
- Which independently identified observations, fields or products are members? composition
- Which accountable role stewards the collection and its usage policy? ownership
Information kind
Observation, retrieval, analysis, forecast and warning are distinguishable assertions. Weather data may feed a climate product without acquiring climate ownership.
Information kind
Observation, retrieval, analysis, forecast and warning are distinguishable assertions. Weather data may feed a climate product without acquiring climate ownership.
- Is this member an observation, retrieval, analysis, forecast or warning reference? classification

- What prevents a forecast or climate normal from being presented as an observed value? constraint
Observations and measurement context Preserve what was sensed and how to interpret its sampling.
Measured result
A meteorological observation carries a value or explicit unavailable state, a defined variable and its sampling support. The proposed fields accommodate surface and upper-air records without making every variable mandatory.

- What value, unit and missing or trace state were actually reported? measurement
- When did the phenomenon occur and when was its result produced or ingested? temporal
- What averaging or accumulation interval and vertical level qualify the measurement? measurement
- What uncertainty, detection limit and quality flag qualify the reported result? quality
Observation source context
A reference to a station, mobile platform, sensor and procedure provides context while their commissioning, maintenance and calibration execution remain externally mastered. Historical location must be resolved at observation time.
Observation source context
A reference to a station, mobile platform, sensor and procedure provides context while their commissioning, maintenance and calibration execution remain externally mastered. Historical location must be resolved at observation time.
- Which station or mobile platform and sensor produced this observation? relationship
- Where was the sampled feature relative to the observing platform at that time? spatial
- Which procedure and calibration evidence were applicable when the sample was taken? provenance
- Which exposure change, relocation or outage limits comparability or availability? exception
Derived atmospheric fields Describe grids, retrievals and analyses without conflating inference with direct sensing.
Field support
A field binds each variable to coordinate and support metadata. Grid spacing is not a claim of effective resolving power; domain edges and absent cells remain explicit.

- Which coordinates, grid mapping and cell bounds locate each field value? spatial
- Which units, statistic and cell methods describe the field variable? measurement
- Which valid times and original calendar qualify the field coordinates? temporal
- Which masked cells, domain limits or sampling gaps must consumers preserve? exception
Retrieval and analysis lineage
A derived atmospheric estimate records its method and input dependencies. Radar, satellite and blended analyses do not become direct point observations; assimilation and retrieval are not assumed interchangeable.

- Which algorithm version and input revisions produced this atmospheric field? provenance
- Was the estimate retrieved, assimilated, interpolated or otherwise transformed? classification
- What validation evidence and uncertainty limits apply to this derived estimate? quality
- Which external Earth-observation product or processing activity remains the source master? relationship
Forecast products and uncertainty Record prediction context without running a forecasting system.
Forecast issue and run
Forecast products retain source model or method, cycle, member role and distinct temporal axes. A nowcast or human forecast can lack a numerical model run and must state its alternative method.
Forecast issue and run
Forecast products retain source model or method, cycle, member role and distinct temporal axes. A nowcast or human forecast can lack a numerical model run and must state its alternative method.
- Which forecast product revision and generating run or method are referenced? identity
- What are the initialization, issue, valid interval and lead time of this forecast? temporal
- Is the forecast deterministic, a named member, an ensemble statistic or a nowcast? classification
- Which earlier product is superseded and what remains available as issued? lifecycle
Probabilistic interpretation
Probability refers to a defined event over specified support. Spread, mean and probability are different products; an ensemble average need not represent a physically realized member.

- Which threshold, inequality, variable, area and interval define the forecast event? definition
- What probability or quantile and sample basis does the product report? measurement
- What calibration or skill evidence applies to this product and use context? quality
- What limitations prevent spread or ensemble mean from becoming a certainty claim? constraint
Weather warning references Preserve authoritative messages and their qualified applicability without issuing alerts.
Warning identity and authority
A local weather record may reference an external warning and its meteorological evidence. CAP-like syntax and attribution alone neither authorize the issuer nor prove a hazard occurred.

A local weather record may reference an external warning and its meteorological evidence. CAP-like syntax and attribution alone neither authorize the issuer nor prove a hazard occurred.
- Which sender, message identifier and sent time identify the warning? identity
- What evidence establishes the issuer remit for this area and warning type? authority
- Is the message actual, draft, exercise or test and what is its message type? classification
- Which observations, forecasts or expert assessments support this warning reference? evidence
Warning area and change history
Warning applicability carries area, timing and source severity/certainty/urgency. Cancellation or expiry changes the message status; it does not prove atmospheric safety.

- Which source area geometry or geocode and altitude range define the warning coverage? spatial
- What effective, onset and expiry times are declared by the warning issuer? temporal
- What severity, urgency and certainty values does the source message assert? state
- Which referenced update or cancellation changes the message chain as of the requested time? event
Evidence continuity and exchange Keep corrections, distributions and fitness evidence traceable.
Quality review and correction
Review history retains original and corrected assertions with their evaluation basis. A flagged value may remain useful for a qualified purpose; a corrected value is not silently substituted into an as-issued forecast evaluation.

What it is Filled
A format-neutral weather information aggregate whose members retain independent source identity and revision. It records local interpretations of observations, atmospheric fields, forecast products and warning references for a declared domain and time scope. It does not own stations, climate archives, hazard response or numerical prediction systems.
In scope
- Collection scope, typed members and atmospheric quantities with time, location, units and measurement context
- Derived fields and forecast products with lineage, sampling support, uncertainty and revision context
- Externally issued weather warning references and local evidence, correction and exchange governance
Out of scope
- Climate normals, long-term trends/extremes, homogenization and climate prediction; these belong to WM-EAR-002
- Station/platform equipment operations, calibration execution, raw EO processing, ocean state and air-quality compliance
- Hazard impact/exposure, emergency decisions, warning issuance/dissemination and numerical weather prediction execution
Why it exists Filled
Describe a bounded collection of observed and predicted atmospheric-state information with traceable sampling, uncertainty and external warning references.
Distinguishing features Derived, awaiting review
- Unlike WM-EAR-002: Proposed optional binding; target version and instance master must be pinned before operational use. Climate owns normals, long-term extremes/trends, homogenized climate series and climate prediction products. Weather supplies versioned inputs and references baselines without computing or governing them.
- Unlike WM-EAR-012: Proposed optional binding; target version and instance master must be pinned before operational use. Environmental Monitoring Station owns station and deployment history. Weather binds time-qualified observation context; fixed stations are optional.
- Unlike WM-EAR-009: Proposed optional binding; target version and instance master must be pinned before operational use. EO Product owns remotely sensed source products. Weather owns only local atmospheric interpretation and provenance references.
- Unlike WM-EAR-005: Proposed optional binding; target version and instance master must be pinned before operational use. Natural Hazard owns occurrence, exposure, consequences and response context. A weather warning reference does not establish a hazard occurrence or trigger a response.
- Unlike WM-EAR-007: Proposed optional binding; target version and instance master must be pinned before operational use. Air Quality owns pollutant assessment and health/compliance interpretation. Weather may reference atmospheric composition as a contextual input.
- Unlike WM-EAR-010: Proposed optional binding; target version and instance master must be pinned before operational use. Ocean / Marine State owns ocean state. Marine weather may share platforms while maintaining the atmospheric variable boundary.
Note: Derived from boundary notes against neighbouring models.
