This requires a US AQI reading of 50 or less, with the closest to 0 being the most optimal and indicating that the air is significantly freer from fine particles, haze, smoke, smog and other harmful chemicals or pollutants in the atmosphere. Some examples of US AQI readings that were recorded on the air quality map in Sacramento midway through 2022 were as follows: Many decent air pollution readings were taken, indicating that there were large swathes of the city that had a good level of air cleanliness, with these areas all falling within the 'good' air quality rating bracket. This is particularly true for certain groups living within Sacramento and other cities throughout the United States and will be covered in more detail later in the article. Some readings from the air quality map taken in late June of 2022 will now be cited and some explanations as to what they mean or indicate will be given, although it should be noted that these numbers can see significant changes, hence why the map should be referred to frequently. Air quality can change rapidly in any area that has a high concentration of people and various industrial activities that often come along with such gatherings. As such, the air pollution map above can or should be referenced regularly, to see what the air cleanliness level is like, and whether or not any pollution spikes are occurring. The air quality map for Sacramento will show readings that are constantly fluctuating over the course of a single day, as well as throughout the month and year. The color makes it easy for people to quickly determine whether air quality is reaching unhealthy levels in their communities.What are the air quality readings on the pollution map for Sacramento? Each category corresponds to a different level of health concern. When AQI values are above 100, air quality is unhealthy: at first for certain sensitive groups of people, then for everyone as AQI values get higher. AQI values at or below 100 are generally thought of as satisfactory. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.įor each pollutant an AQI value of 100 generally corresponds to an ambient air concentration that equals the level of the short-term national ambient air quality standard for protection of public health. The higher the AQI value, the greater the level of air pollution and the greater the health concern. Think of the AQI as a yardstick that runs from 0 to 500. AQI is EPA’s index for reporting air quality. The goal of the project is to provide additional air quality information during wildfires – especially in areas with no AirNow monitors. Forest Service have launched a pilot project to show data from low-cost sensors on the Fire and Smoke Map. AirNow Fire and Smoke MapĪirNow and the U.S. This is why you may see good air quality being indicated for Shasta Lake when there may be smoke present. In Shasta County, the Anderson and Redding stations are the only stations monitoring for particulate matter (smoke). The Shasta Lake sites only monitor for Ozone pollution which is not related to smoke from wildfires. It is important to understand that not all air monitoring stations monitor for particulate matter (smoke). The map you see below identifies the permanent, official, air monitoring stations in the north state. The Shasta Lake station monitor for ozone pollution only. Particulate Matter (smoke) monitoring is only available at the Anderson and Redding monitoring stations.
