Atmosphere Weather & Climate

This meta-model describes the state of the atmosphere: what was observed, what is predicted, and what the long record says is normal. It holds observing stations and their measurements, gridded and remotely sensed fields, forecast products and the warnings drawn from them, and the homogenized series and normals that make decades comparable. It is its own model because weather is a continuously refreshed observation stream while climate is a curated statistical archive, and both must live under one identity so that a warning, a forecast and a normal for the same place can be reconciled. Hazard consequence and exposure are modelled in P9; here the subject is the atmospheric state itself.

Bundles and layers

Bundle

observation

What was measured, by what, where and how well

Layers

stationNetwork`: observing sites, instruments, exposure class and operating history · `surfaceAndUpperAir`: direct measurements at the surface and through the profile · `remoteSensing`: radar, satellite and lidar derived fields with their retrieval method · `atmosphericComposition`: aerosols, ozone and greenhouse gas concentrations

Bundle

forecast

What is expected and what is communicated about it

Layers

numericalPrediction`: model runs, ensembles, initialization and lead times · `productAndBulletin`: published forecast products for areas, points and routes · `warningAndAdvisory`: severity-graded warnings with area, onset, certainty and expiry

Bundle

climatology

What the long record says

Layers

homogenizedSeries`: quality-controlled long series with break adjustments and lineage · `normalsAndExtremes`: reference-period normals, records and exceedance statistics

Findings

Catalogue-native findings must describe the information grouped by each layer. This legacy version does not declare them separately.

Questions & artifacts

Questions, artifact requirements and serial naming rules are required by Vercy vNext; they remain unassigned in this reference version.

  • `observationFeedContract`: terms for push or pull delivery of the observation stream, including latency, quality flags and correction handling
  • `warningDisseminationContract`: terms for redistributing warnings to broadcasters and applications, including timeliness and no-alteration conditions

Ownership, roles & access

An ecology commons steward operates the observing and forecasting register: it runs or accredits stations, publishes forecasts, warnings and the climate archive, and states the quality of each product. Restricted feeds, pre-validation data and commercially licensed products are released through S2 access contracts granted by the steward, and reads are recorded in S4.

Objects, relationships, events and projections

Objects

  • `observingStation`: a site producing atmospheric measurements; key attributes: station identifier, location, elevation, instrument set, exposure class, operating period
  • `observedVariable`: the quantity being measured; key attributes: standard name, unit, sampling interval, measurement height, uncertainty
  • `weatherObservation`: a measured value at a place and time; key attributes: timestamp, station reference, variable reference, value, quality flag, correction status
  • `griddedField`: a spatial field of an atmospheric variable; key attributes: variable, grid geometry, valid time, source (analysis, retrieval, model), resolution
  • `forecastProduct`: a published prediction for an area or point; key attributes: issue time, valid period, lead time, variables, confidence expression
  • `warning`: a graded notice of expected hazardous weather; key attributes: phenomenon, severity, certainty, urgency, area geometry, onset, expiry, status
  • `climateSeries`: a long, quality-controlled record for a site or area; key attributes: variable, period of record, homogenization method, break points, completeness
  • `climateNormal`: a statistic over a reference period; key attributes: variable, reference period, statistic type, value, computation method

Relationships

  • `weatherObservation` -> recordedAt -> `observingStation` (n:1): each value carries the site that produced it
  • `weatherObservation` -> quantifies -> `observedVariable` (n:1): values are meaningless without the standard-named quantity and unit
  • `griddedField` -> assimilates -> `weatherObservation` (n:m): analyses and retrievals declare the observations behind them
  • `forecastProduct` -> initializedFrom -> `griddedField` (n:m): products trace to the analysis and model run they came from
  • `warning` -> derivedFrom -> `forecastProduct` (n:1): a warning names the prediction that justified it
  • `climateSeries` -> aggregates -> `weatherObservation` (1:n): the long record is built from validated observations
  • `climateNormal` -> computedFrom -> `climateSeries` (n:1): normals are always tied to the series and period used
  • `observingStation` -> succeededBy -> `observingStation` (n:1): relocations and replacements form a traceable site lineage

Events

  • `observationRecorded`: a measurement was taken and entered the observation stream
  • `observationCorrected`: a previously published value was flagged, adjusted or withdrawn after quality control
  • `forecastRunCompleted`: a prediction cycle finished and its fields became available for products
  • `warningIssued`: a graded notice was published for an area, with onset and expiry
  • `warningUpdatedOrCancelled`: an active notice was upgraded, downgraded, extended or withdrawn
  • `stationCommissionedOrRelocated`: an observing site started, moved or changed instrumentation, creating a potential series break
  • `seriesHomogenizationApplied`: an adjustment was applied to a long record to remove a non-climatic break
  • `recordValueSet`: an observation exceeded the previous extreme for a site or area

Projections

  • `publicForecastView`: point and area forecasts with plain severity language; omits model internals, ensemble members and station diagnostics
  • `warningFeed`: machine-readable current warnings with area, severity, onset and expiry; omits the forecasting rationale and internal deliberation
  • `climateNormalsTable`: normals and extremes per site and reference period; omits raw uncorrected observations
  • `stationMetadataCatalogue`: site, instrument and exposure history for data users; omits measured values
