56 of 251 measured days were over the WHO 24-hour guideline (15 µg/m³). 114 days without a value: 3 with no readings from the monitors, 111 with readings for part of the day (a day needs 18 hours); point at a grey square for its reason (why days go blank). One row per month, one square per local day.
