Air quality today
The air quality in Charette today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
Measurements recorded for this assessment show a PM2.5 reference value of 8.8, based on two valid observations. Data is shown via OpenAQ. 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 air‑quality record for Charette currently includes measurements of ozone (O₃) and fine particulate matter (PM₂.5). There are two recent observation rows in the dataset, one for each pollutant, and both were last updated on 2026-02-10 at 22:00 UTC, which places them well within the three‑day freshness window.
For ozone, the single reported value is 0.031 ppm. Because there is only one measurement, the minimum, median, maximum and the 10th‑ and 90th‑percentile figures are all identical at 0.031 ppm, indicating no observed variability in the data set for this pollutant. The PM₂.5 reading stands at 8.8 µg/m³, again with a uniform statistical profile across min, median, max, p10 and p90 because only one row is present.
These figures illustrate that the dataset provides a very narrow snapshot of conditions in Charette: each pollutant is represented by just one recent observation, so there is no range or spread to describe temporal changes. The coverage is limited to a single monitoring location for each contaminant, meaning spatial variation across the city cannot be assessed from this source alone. While the timestamps are fresh, the lack of multiple rows means that any day‑to‑day fluctuations or differences between neighborhoods remain undocumented in the current record.
