Air quality today
The air quality in Kanda today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 4.0 µg/m³ based on five valid readings.
Overall conditions meet the criteria for the Good category, and no other pollutants are highlighted in the current assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Kanda air‑quality dataset contains observations for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All of these measurements come from a single monitoring location, identified as 京都郡苅田町富久町１丁目１９－１, so the city’s reported values reflect conditions at one point rather than a network of sites.
Each pollutant shows an identical timestamp for its most recent reading: 2026‑02‑10 22:00 UTC, and the source notes that this data was “Updated within 3 days.” Because there is only one row in the table (rt = 5 pollutants, st = 1 station), the coverage is limited to a single spot and cannot capture spatial variation across Kanda. The values themselves are tightly clustered: NO registers at 0.0 ppm, while NO₂ and NOX both sit at 0.003 ppm, SO₂ at 0.001 ppm, and PM2.5 records a constant 4.0 µg/m³. For each pollutant the minimum, median, maximum, 10th percentile and 90th percentile are identical, indicating no observed spread in the data for the period covered.
Overall, the dataset is very fresh – every measurement was logged on the same day and is marked as recent – but its breadth is narrow, with only one monitoring point and a single set of values per pollutant. Consequently, while the numbers give an up‑to‑date snapshot of air quality at that specific address, they do not represent the full range of conditions that may occur elsewhere in Kanda or over longer time frames.
