Air quality today

The air quality in Phimpha is currently classified as Moderate. According to the latest assessment, the primary pollutant is PM2.5, which represents fine particulate matter. The most recent measurement records a PM2.5 concentration of 33.46 µg/m³. No PM10 data is reported for this period. The evaluation incorporates five valid measurements collected from the monitoring network.

All figures are provided through OpenAQ, which aggregates publicly available monitoring data. The five measurements were taken from distinct monitoring stations within the city area. Values are expressed in micrograms per cubic meter, the standard unit for particulate concentrations. The reported concentration reflects the current observed level at the time of measurement. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Phimpha pulls five measured variables – PM1, PM2.5, relative humidity, temperature and UM003 – from three monitoring stations that together contributed fifteen recent rows. All of the values were recorded at the same moment, 2026-01-29 06:00 UTC, and each pollutant’s latest reading is marked as updated within the past thirty days, so the snapshot is current even though it represents a single point in time.

Across the three stations the PM1 concentrations range from about 23.98 to 32.15 µg/m³, with a median of roughly 26.07 µg/m³, indicating modest variation around the central value. PM2.5 shows a broader spread, moving between 33.46 and 47.97 µg/m³ and centering near 38.96 µg/m³. Relative humidity values sit between 32.91 % and 56.25 %, with a typical level of 44.95 %, while temperature fluctuates from 29.44 °C up to 33.04 °C and averages around 32.36 °C. The particle count measured as UM003 is the most variable, ranging from 1 481 to 2 429 particles per cubic centimetre and clustering near 1 644 particles/cm³.

Because the data set consists of only three stations, the spatial coverage for Phimpha is limited; conditions can differ across neighborhoods that are not directly represented by these points. The uniform timestamp means the figures capture a moment rather than ongoing trends, so while the numbers are fresh, they do not convey how the city’s air quality changes over the course of a day or week. Users should keep in mind that the snapshot provides a concise but narrow view of the current atmospheric state.
