Daily averageHigh / low outside range
Bars show daily averages. Dots mark highs or lows outside the range, measured from five-minute averages.
How to read this report
Daily bars show averages of the available readings. Missing intervals are excluded. Amber dots mark the highest or lowest five-minute averages outside the report range. A bar is amber when the daily average itself is outside that range. Hover or focus a day for its average, minimum, maximum and time outside the range.
Time outside a range is estimated from five-minute averages. Missing intervals are excluded from averages and are never counted as clean air. Coverage is calculated separately for each metric over the full period.
Changes compare the share of recorded time outside the same range. A comparison needs at least 80% coverage for that metric in both periods. Monthly reports include every day of the calendar month.
Report criteria: CO₂ above 800 ppm; PM2.5 above 12 µg/m³; temperature outside 20–25 °C; humidity outside 40–60%. These are reference ranges for this report, not a health score. Findings are calculated from the same recorded history you can explore in the charts.
