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 Oțelu Roșu air‑quality record consists of five measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulfur dioxide (SO₂) – gathered from a single monitoring station. The dataset contains one row per pollutant, so the overall coverage is limited to this solitary source.
Freshness varies considerably across the five compounds. The most recent NO₂ and PM₁₀ values were logged on 2026‑02‑10 at 19:00 UTC, making them the only measurements updated within the last seven days. Ozone data are older, with its latest entry dated 2022‑03‑06 at 22:00 UTC, while CO and SO₂ both trace back to 2025‑11‑15 at 08:00 UTC. Consequently, three of the five pollutants rely on information that is more than a year old.
The numeric values themselves show little spread because each pollutant currently has a single recorded measurement. NO₂ sits at 13.80967 µg/m³, O₃ at 45.72861645 µg/m³ and PM₁₀ at 18.97143 µg/m³; these figures also serve as the minimum, median and maximum for their respective series. CO is reported as –1000.0 µg/m³ and SO₂ as –1.0 µg/m³, both flagged as old data, indicating possible sensor errors or placeholder values rather than realistic concentrations.
Overall, the dataset provides a snapshot of five pollutants from one location, but most of the information is dated, with only NO₂ and PM₁₀ offering recent updates. Users should keep in mind that air‑quality conditions can differ across neighborhoods and over time, and the current data may not reflect present‑day variations throughout Oțelu Roșu.
