Air quality today

The air quality in Commerce City, Colorado is rated as Good today. The primary pollutant measured is PM2.5 (fine particles). Recent observations show a PM2.5 concentration of 2.9 µg/m³ and a PM10 level of 31.0 µg/m³ based on five valid measurements reported through OpenAQ.

These values reflect the current monitoring snapshot for the area. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Commerce City’s OpenAQ feed currently includes six measured variables: PM2.5, PM10, PM1, relative humidity, temperature and UM003 (particle concentration). The dataset draws from 14 rows of raw measurements across seven distinct monitoring stations. Freshness varies markedly by pollutant. Both PM2.5 and PM10 have recent entries dated 2026‑02‑11 00:00 UTC, meaning the newest values were recorded within the past week. In contrast, the remaining four variables – PM1, relative humidity, temperature and UM003 – come from a single older record captured on 2025‑04‑12 21:00 UTC, which OpenAQ flags as “old data”. One row is classified as unknown, while eight rows are labeled old, leaving only five rows with recent updates.

The most current PM2.5 reading is 2.9 µg/m³ (Adams‑Birch) with a median of 4.51 µg/m³ across the seven recent samples; values span from a low of 2.9 up to an extreme maximum of about 1,648 µg/m³, placing the 90th percentile at roughly 671 µg/m³. PM10 shows a median of 31.0 µg/m³ (Adams‑Birch) and ranges from 2.02 to 100.2 µg/m³, with the 10th and 90th percentiles at about 7.8 and 86.4 respectively. By comparison, PM1 is represented by a single figure of 1,647.45 µg/m³ (Commerce City School), matching its minimum, median and maximum because no recent samples exist.

Humidity, temperature and UM003 each have one historic value – 6.97 % relative humidity, 28.25 °C temperature and 213.51 particles/cm³ – all recorded at the same time in April 2025. Because most rows are old or unknown, the dataset provides limited insight into current day‑to‑day conditions; spatial and temporal variation across Commerce City may therefore be under‑represented until more recent measurements become available.
