Highest aqi

The World Air Quality Index project has exercised all reasonable skill and care in compiling the contents of this information and under no circumstances will the World Air Quality Index project team or its agents be liable in contract, tort or otherwise for any loss, injury or damage arising directly or indirectly from the supply of this data. Data on this site is presented in Standard Time at the time the measurement ended. An individual score (Individual Air Quality Index , IAQI) is assigned to each pollutant and the final AQI is the highest of these six scores.

The final AQI value can be calculated either per hour or per hours. The concentrations of pollutants can be measured quite differently. Highest 5” current conditions could change several times in a single day.

According to the Environmental Protection Agency, three out of the top five cities with the highest Air Quality Index ( AQI ) in the United States were in Utah at various points throughout the day:. Think of the AQI as a yardstick that runs from to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern.

For all but days, the air in Hilo was considered unhealthy, or worse, for sensitive groups. The smog that issues forth from the volcano is so regular that locals have a word for it: vog. Hint: living in area with unhealthy air quality can affect your insurance rates.

Current Air Quality Index ( AQI ) Conditions - California Cities. Please select a city for detailed current conditions and forecasts. AQI : Unhealthy for Sensitive Groups (1- 150) Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air. Keep track of the most polluted cities in the world with our air quality index ( AQI ) ranking. The highest of these AQI values is reported as the AQI value for that day.

In large cities (more than 350people), state and local agencies are required to report the AQI to the public daily. Many smaller communities also report the AQI as a public health service. The monitoring data presented on this webpage contains real-time continuous data that have not been through a full quality assurance review. These data should be considered unofficial. The area ranks highest in annual and 24-hour peak averages in fine particulates.

PM-is measured at standard pressure and temperature conditions. The GAIA air quality monitoring stations are using high-tech laser particle sensors to measure in real-time PM2. Very easy to set up, they only require a WIFI access point and a USB power supply.

Orange County evokes thoughts of warm California sun and its county seat is near the top of the list when it comes to having the best overall air quality. Much like its neighbor Anaheim, Santa Ana is in the Top despite being in an area of the country normally associated with smog and dirty air. AQI 90th ile percent of daily AQI values during the year were less than or equal to the 90th percentile value. AQI Median Half of daily AQI values during the year were less than or equal to the median value, and half equaled or exceeded it.

For major metropolitan areas, the measurements are converted to AQI values, and the pollutant with the highest AQI is reported daily. Oregon’s index is based on three pollutants regulated by the federal Clean Air Act: ground-level ozone, particle pollution and nitrogen dioxide. The System of Air Quality Weather Forecasting and Research (SAFAR), which has been taking readings at locations in Mumbai, measured the air quality index ( AQI ) at 32 which falls in the.

For example, if values are for ozone and for nitrogen dioxide,. Forecast updated: Wind: hours ago, fine particulate matter: hours ago, ozone: hours ago.
