Meteogram Air Quality & Pollen
Meteogram Air Quality & Pollen shows a 3-day forecast of air quality and pollen conditions. It visualises:
• Common Air Quality Index (CAQI) scale from 1 (good, green) to 100 (bad, red).
• Particulate matter: PM10 (particles ≤10 μm) and PM2.5 (particles ≤2.5 μm).
• Desert dust concentrations.
• Air pollution gases: ozone (O₃), sulphur dioxide (SO₂), and nitrogen dioxide (NO₂).
• Pollen forecasts for selected locations (no official colour coding).How it works
• CAQI uses the "background" index, not the "roadside" index, since small-scale road effects cannot be resolved by weather models.
• PM10 and PM2.5 represent fine particles that can penetrate deep into the lungs; desert dust contributes to elevated values.
• Ozone forms in the lower troposphere, especially in urban areas, and impacts respiratory health.
• SO₂ and NO₂ mainly originate from burning fossil fuels, reacting to form harmful secondary pollutants.
• Time axis uses local time valid when the forecast is created.Limitations
• Forecasts are based on atmospheric models at 12 km resolution; local concentrations may differ.
• Roadside measurements are typically higher than background forecasts.
• Pollen forecasts lack a unified colour coding system.
• Not suitable as a replacement for official air quality warnings.Best use cases
• Monitoring regional air pollution and pollen exposure risk.
• Supporting health-related planning for sensitive groups (e.g. asthma, COPD, allergies).
• Tracking pollution trends and seasonal variations.Access
