How to interpret this evidence

What this shows: station observations over time for one pollutant, useful for linking climate conditions to health outcomes.

How to use with health data: compare spikes against clinic/health indicators in the same period and geography.

Metric context: This metric should be interpreted with local station metadata, weather context, and health outcomes for complete analysis.

Standards shown: WHO guideline and NAAQIS reference lines are shown where threshold values are available for the selected pollutant and temporal resolution.

Data note: zero values are shown as zero; only null values are treated as missing and excluded from the chart.
