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 current station data listed for this city is focused on particulate matter (PM). Only PM2.5 measurements are available, coming from three monitoring rows that together represent three distinct sensor locations. The most recent reading was recorded on 2026-02-10 23:02 UTC, and two of the three rows have updates within the past seven days, while one row’s timestamp is unknown. This means the dataset provides fairly fresh information for most sites but does not cover any other pollutants.
Across the three stations, PM2.5 values range from a low of 16.32 µg/m³ to a high of 32.25 µg/m³, with a median concentration of 23.01 µg/m³ at the C3 Road (5th Avenue) – Rizal Avenue Extension location. The spread between the 10th percentile (17.66 µg/m³) and the 90th percentile (30.40 µg/m³) shows moderate variability among the sites. Because only three rows contribute data and one lacks a recent timestamp, the picture of air quality in Caloocan is limited to these points in time and space; conditions elsewhere or at other times may differ.
