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 May District air‑quality record draws from a single monitoring site that contributed five rows of data, each representing the most recent reading for a different pollutant. All measurements were last updated on 2026-02-10 12:00 UTC, which falls within the “updated within 7 days” freshness category, so the dataset reflects conditions captured only once rather than over an extended period.
The available pollutants are PM1 at 15.75 µg/m³, PM2.5 at 24.82 µg/m³, relative humidity at 50.63 % , temperature at 26.16 °C and particle count (UM003) at 1 040.23 particles/cm³. Because each pollutant has a single recorded value—the minimum, median and maximum are identical—there is no observable spread or variability in the data for May District. This uniformity indicates that the current snapshot cannot reveal how concentrations change throughout the day or across different locations within the district.
With only one station feeding all five rows, coverage is limited to the conditions at that specific point. While the timestamps are recent, the lack of multiple stations or repeated measurements means the dataset does not capture spatial or temporal fluctuations that may occur elsewhere in May District. Consequently, any single reading should be understood as a momentary glimpse rather than a comprehensive picture of the district’s air quality.
