The Air Quality Index (AQI) is a simple, color-coded, unitless index that is an effective way to communicate air pollution concentrations to the general public The AQI provides an indication of the quality of the air and its health effects Options exist for scaling the AQI categories to PM2.5 and PM10 concentration values (✪g/m3 . It is a health protection tool used to make decisions to reduce short-term exposure to air pollution by adjusting activity levels during increased levels of air pollution Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality
The AQI uses a normalized scale from 0 to 500. Since levels rarely exceed a value of 200 in the United States, in most cases only the range from 0 to 300 is shown. The higher the AQI value, the greater the level of pollution and the greater the health concern AQI Range: 0..50. 50..100. 100..150. 150..200. 200..300. 300..400. 400..500. The above calculator is based on the work from the US EPA Air Now calculator, available at airnow.gov
The Air Quality Index (AQI) is used for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air Air Quality Index Scale . 0 - 50. Good. 51 - 100. Moderate. 101 - 150. Unhealthy for Sensitive Groups (USG) 151 - 200. Unhealthy. 201 - 300. Very Unhealthy. 301 - 500. Hazardous. Values above 500 are beyond the AQI scale.

How does the AQI work? Think of the AQI as a scale that runs from 0 to 500. The higher the AQI value the greater the level of air pollution, and the greater the health concern. For example, an AQI value of 50 represents good air quality with little potential to affect public health, while an AQI value over 300 represents hazardous air quality Air Quality Rating Scale Basics. The first air quality rating scale, the Air Quality Index (AQI), was developed in the 1970s by the U.S. Environmental Protection Agency (EPA). The AQI is used to report the daily air-quality forecast in metro areas with populations greater than 350,000 AQI, or Air Quality Index, translates the five main air pollutants regulated by the Clean Air Act: sulfur dioxide, nitrogen dioxide, carbon monoxide, ground-level ozone, and particle pollution into a number ranging from 0 to 500 along with a color corresponding to specific health risk levels.

Air Pollutants. The EPA has identified six pollutants as criteria air pollutants because it regulates them by developing human health-based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels. These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution. AQI, or Air Quality Index, is a system for translating sometimes confusing or unintuitive pollutant concentration measurements, into one easy-to-understand scale to clearly represent the health risk posed by ambient air pollution. The index formula usually considers up to 6 main pollutants (PM2.5, PM10, carbon monoxide, sulfur dioxide, nitrogen. Health Effect Category based on PM2.5 Concentration.

The EEA's air quality database consists of a multi-annual time series of air quality measurement data and calculated statistics for a number of air pollutants Air Quality Data. The U.S. Embassy air quality monitor measures airborne fine particulate matter (commonly referred to as PM 2.5 because they are less than or equal to 2.5 microns in diameter) on the compound of the Embassy in Kabul. Data from a single monitoring station cannot be applied to an entire city. Therefore, air quality data collected. When Beijing's realtime air quality index (AQI) showed a reading of 999, Tokyo recorded 42, Sydney 17 and New York 26. Hong Kong and Taiwan recorded moderate readings of 66 and 87. The Air Quality Index reflects the air pollutant rates on a scale from good (50) to hazardous (300-500). While the scale only goes up to 500, the Spokane Regional Clean Air Agency can measure.
Air pollution reduces air quality and thus is a major risk to health. Air pollution causes to a number of health concerns such as asthma, allergies, lung disease, anxiety and depression. Babies, young children, teenagers, the elderly, pregnant women and people with preexisting respiratory medical conditions are especially vulnerable to air. An air-quality monitor atop the United States Embassy recently measured an air quality index well above 500, which is supposed to be the top of the scale

The AQI is an index used for reporting forecasted and daily air quality. The AQI uses color-codes and a numerical scale to report how clean or polluted the air is and what associated health effects might be of concern. The AQI focuses on health effects people may experience within a few hours or days after breathing polluted air Both are used to measure the air quality in a general area. The pros both make use of easy-to-use color scales (green to maroon) and numerical ratings, with the AQI using a scale of 0 to 500 and the AQHI using a scale of 1 to 10+. When directly compared, the AQI can be more precise due to a larger scale of measurement For each pollutant, the AQI transforms ambient concentrations to a scale from 0 to 500. The AQI is keyed as appropriate to the national ambient air quality standards (NAAQS) for each pollutant. In most cases, the index value of 100 is associated with the numerical level of the short-term standard (i.e., averaging time of 24-hours or less) for.
Air Quality in Clark County. How clean is the air in your metropolitan area or county? Use this map to find out. The U. S. Environmental Protection Agency (EPA) has provided a scale called the Air Quality Index (AQI) for rating air quality Atmospheric Composition and Air Quality. GFDL scientists aim to advance our understanding of earth's past, present, and future atmospheric composition and climate. We develop sophisticated computer models representing the emissions, transport, chemical transformations, and sinks of trace gases and aerosols throughout the troposphere and. The scale for each pollutant is non-linear, as is the final AQI score. Thus an AQI of 100 does not mean twice the pollution of AQI at 50, nor does it mean twice as harmful. While an AQI of 50 from day 1 to 182 and AQI of 100 from day 183 to 365 does provide an annual average of 75, it does not mean the pollution is acceptable even if the. Air Quality Network Map. The current air quality map is designed to help you plan your day by offering current air quality and general forecast information. The dot color indicates the latest air quality level for each monitoring station. Updated daily, the larger regions are also shaded colors, based on the day's expected air quality.
