EU Air Quality Assessment Method Records — EEA

Keyless. Pay per record. How each European air-quality objective is officially assessed — regime, method, zone, and pollutant.

This actor turns the European Environment Agency (EEA) Air Quality e-Reporting dataflows into clean, per-record data — the assessment methods member states officially use to judge each air-quality objective. Each run reads the EEA's keyless DiscoData SQL service and delivers one row per assessment-method record, structured for air-quality methodology and coverage analysis, reusable with acknowledgement of the EEA, with no personal data of any kind.

What this is, in one paragraph

Under the EU Air Quality Directives, each pollutant objective in each zone is assessed by a declared method — fixed measurement, modelling, objective estimation, and so on. This actor reads that assessment-regime-methods dataflow and delivers one record per regime / method / zone / pollutant / year: the country, the assessment regime and the assessment METHOD linked to it, the zone, the pollutant, the protection target and objective type, the reporting metric, and the assessment type and description — all carried as filed. It is the method-resolution layer of Europe's air-quality assessment.

Who buys this and for what job

• Air-quality methodologists auditing how each objective is assessed across zones and pollutants
• Regulatory and consultancy teams tracing the assessment method behind an air-quality classification
• Researchers studying the mix of measurement vs modelling in air-quality assessment
• Data engineers who want the air-quality assessment methods table as clean rows from a keyless source.

EEA licence — reuse with acknowledgement

One licence rider travels on every record. EEA data may be reused, including commercially, provided the source is acknowledged: "Source: European Environment Agency (EEA)." Where third-party content is marked, it keeps its own terms. These are reported values as filed — not a compliance verdict.

Zone/method grain — no person data

The unit of every record is a regime-to-method link for a zone and pollutant — a methodology line, never a person. There is no contact, operator, or responsible-person field in the source, and none is selected or emitted; a person-key guard runs on every record as a backstop.

Output

One JSON object per assessment-method record. Real example (values as reported):

  "record_id": "ARE-AT_60_00020_LV_aMean_2016:SPO.06.G10.65764.20.1",
  "country": "Austria",
  "country_code": "AT",
  "reporting_year": 2016,
  "assessment_regime_id": "ARE-AT_60_00020_LV_aMean_2016",
  "assessment_method_id": "SPO.06.G10.65764.20.1",
  "zone_id": "ZON-AT_60",

  "protection_target": "Health",
  "objective_type": "Limit Value (LV)",

  "source": "EEA Air Quality e-Reporting \u2014 assessment regime methods",
  "observed_at": "2026-08-22T00:00:00Z"
}

An unbilled RUN_RECEIPT records the robots check, the filters, rows seen and delivered, and whether charged equals delivered.

Field reference

Each record is one regime-method link. Identity: record_id, country, country_code, reporting_year, preliminary, assessment_regime_id, assessment_method_id, and zone_id. Objective: air_pollutant, protection_target, objective_type, and reporting_metric. Method: assessment_type, assessment_type_description, assessment_method, and source_data_url. Provenance travels on every record: source, source_url, licence, attribution, disclaimer, and observed_at.

How a run works

A run first re-reads the source host's robots posture from your runtime — the EEA DiscoData host — and stops at the door if that ever changes. It pages the air-quality assessment methods table (filtered to your optional countryCode and optional year), and flattens each row to one record — carrying every value verbatim, never anything person-shaped — delivered before it is charged, so a blocked or empty run costs you nothing. The actor stops at your maxRecords ceiling and records charge_equals_delivered in the receipt.

Coverage and scope

The table holds on the order of 802,938 rows. Because each record carries the assessment_regime_id, assessment_method_id, air_pollutant, and zone_id, segmenting is straightforward. Pull one slice, or the whole table to seed a warehouse.

Working with the data

The methods are an audit layer, and the fields make them traceable. Because every record links an assessment_regime_id to an assessment_method_id with the assessment_type (fixed measurement, modelling, objective estimation), an analyst can see exactly how a pollutant objective is assessed in a given zone, and count the mix of assessment types across zones. The reporting_year frames each method in its reporting cycle.

Identifiers and joins

Every record carries the assessment_regime_id and zone_id, keying each method to the assessment-regime cell (the thresholds and coverage counts for the same regime) and, via zone/pollutant, to the station-statistics cell — on shared identifiers.

Measurement versus modelling

A persistent question in air-quality policy is how much of the assessment rests on physical measurement versus modelling and objective estimation. Because every record carries the assessment_type and assessment_method for a specific regime, zone, and pollutant, this dataset answers that question directly: an analyst can quantify, per country or per pollutant, the share of objectives assessed by fixed measurement against those assessed by model or estimation, and track how that mix shifts across reporting years. Paired with the assessment-regime cell's coverage counts, it gives a complete view of both the method chosen and the monitoring effort behind it.

Cost guidance

One aq_assessment_method_record per delivered row: cost = rows delivered × your plan's per-record price. Scope with countryCode and year to keep runs bounded. 1,000 rows is $50 (Free) / $33.50 (Gold).

A stable methodological backbone

Because assessment methods change slowly and are reported every year, this dataset also serves as a longitudinal record of methodological continuity: an analyst can see when a zone switched a pollutant from objective estimation to fixed measurement, or introduced modelling, and align those transitions with changes in the reported station statistics. That makes the method table a natural companion to any air-quality trend analysis, where a break in a series is often a change of method rather than a change in the air.

Honest limitations

• As reported. Values, flags, and thresholds are as filed; this actor reformats, it does not audit or recompute.
• A label, not a verdict. These are reported statistics/regimes/volumes/loads, not an independent compliance assessment.
• Acknowledge the EEA. The acknowledgement travels on every record.
• No person data of any kind.

Differentiation

This is a net-new category for the NexGenData fleet. It is distinct from eu-air-quality-assessment-regime-records — that cell carries the REGIME coverage (thresholds and monitoring/model counts per zone), while this cell resolves the specific METHOD used to assess each objective; method resolution vs regime coverage. Its specific job is the EU air-quality assessment methods.
