Air quality today
The air quality today in Crow Wing County is rated as Good. The primary pollutant identified is PM2.5 (fine particles). One valid measurement supports this assessment.
The reported PM2.5 concentration is 3.3 µg/m³, while no PM10 value is available. 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 Crow Wing County includes two pollutants: ozone (O₃) and fine particulate matter (PM₂.5). Data come from a single monitoring location in Brainerd, so the dataset represents one site rather than a network of stations across the county. The most recent ozone reading is 0.037 ppm, recorded on 2025‑11‑04 at 19:00 UTC; this entry is flagged as “old data,” indicating it is not from the last seven days. In contrast, the latest PM₂.5 measurement is 3.3 µg/m³, logged on 2026‑02‑10 at 23:00 UTC and classified as “updated within 7 days.” Because only one row falls into the fresh‑data category, the overall freshness of the dataset leans toward older observations.
Both pollutants show a single recorded value with no variation across the limited sample. For ozone, the minimum, median, and maximum are all 0.037 ppm, meaning there is no observed spread in the data. PM₂.5 mirrors this pattern, with its minimum, median, and maximum each equal to 3.3 µg/m³. The lack of multiple readings prevents any assessment of typical ranges or fluctuations over time.
Given that only one monitoring site supplies data for both ozone and particulate matter, coverage is narrow and may not capture spatial differences within Crow Wing County. The freshest timestamp belongs to PM₂.5, while the ozone record remains several months old. Users should keep in mind that air‑quality conditions can change across locations and days, and the current dataset provides a limited snapshot rather than a comprehensive view of the county’s atmosphere.
