Hourly PM2.5 and PM10 AQI If viewing/calculating hourly PM2.5 or PM10 AQI for hours >5 old , these calculations are done by using the midpoint 24-hour average concentration converted to AQI. For a given hour, this includes the previous 12 hours, the given hour, and the following 11 hours. Particulate Matter (PM2.5) Trends. Read the air pollution in Phuket, Thailand with AirVisual. 3. Get real-time, historical and forecast PM2.5 and weather data. Discover AirVisual Map, live world air pollution and air quality index (AQI) interactive 2D animated map combining PM2.5 data from public government, air quality stations, our community. For example, if the PM2.5 AQI is 125, the PM10 AQI is 50, SO2 is 30, NOx is 50, and all other pollutants are less than 125, then the AQI is 125–determined ONLY by the concentration of PM2.5 . Cupertino Air Quality Index (AQI) is now Good. This PM2.5 reading of 18.2 µg/m³ placed it in the “Moderate” category (12.1-35.4 µg/m³). This figure was 25 US AQI with a PM2.5 concentration of 6.1 µg/m³. The AQI is determined by the pollutant with the highest index. Phuket Air Quality Index (AQI) is now Good. The 2019 average for Metro Manila was 18.2 US AQI which placed it as the 5 th most polluted city in all of the Philippines. EPA has identified data quality issues affecting PM 2.5 monitoring data in some states. Wuhan PM2.5 (fine particulate matter) AQI is 19 - Wuhan PM10 (respirable particulate matter) AQI is 7 - Wuhan NO2 (nitrogen dioxide) AQI is 16 - Wuhan SO2 (sulfur dioxide) AQI is 7 - Wuhan O3 (ozone) AQI … Air Quality Index (AQI) Calculation The Air Quality Index is based on measurement of particulate matter (PM 2.5 and PM 10), Ozone (O 3), Nitrogen Dioxide (NO 2), Sulfur Dioxide (SO 2) and Carbon Monoxide (CO) emissions.Most of the stations on the map are monitoring both PM 2.5 and PM 10 data, but there are few exceptions where only PM 10 is available. What are the main sources of air pollution in Manilla? In 2019 the average reading of fine particulate matter in the air, or PM2.5, was found to be concentration of 22.8 μg/m 3. More information. Read the air pollution in Cupertino, California with AirVisual. The U.S. AQI does not include recommendations for PM2.5 levels above 500, but levels are sometimes worse (“beyond index”). This puts it at a ‘moderate’ rating according to the US Air Quality Index, which according to the stringent US standards of measurement, is any number between 12.1 to 35.4μg/m 3. Get real-time, historical and forecast PM2.5 and weather data. PM 2.5 Data Omitted from Air Trends Assessment. Wuhan Air quality index Updated on 2021-02-26 10:00:00 , Wuhan AQI (Air quality index) is 19. News (Jan 2016): The readings for the Hanoi CEM Station are abnormally low, so the PM2.5 AQI calculation has been again re-adjusted by a factor of 30 to reflect the current conditions. This data is not included in the PM 2.5 trends assessment or summary tables on this website.
