8 of 226 measured days were over the WHO 24-hour guideline (15 µg/m³). 139 days without a value: 2 with no readings from the monitor, 1 with readings for part of the day (a day needs 18 hours), 136 with under 18 hours of readings or readings that failed our checks; point at a grey square for its reason (why days go blank). One row per month, one square per local day.
