Be On The Watch For These Knuckleheads     
AQI: GoodAQI: Good is (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: ModerateAQI: Moderate is (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms.
AQI: Unhealthy for Sensitive GroupsAQI: Unhealthy for Sensitive Groups is (101 - 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.
AQI: UnhealthyAQI: Unhealthy is (151 - 200)
Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.
AQI: Very UnhealthyAQI: Very Unhealthy is (201 - 300)
This would trigger a health alert signifying that everyone may experience more serious health effects.
AQI: HazardousAQI: Hazardous is (greater than 300)
This would trigger a health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Thursday, a low-pressure system will impact the Sacramento area, producing increased onshore flow and partly cloudy skies that will limit ozone formation. As a result, ozone levels will be Good. Friday, surface high pressure building over western Oregon will generate moderate northwesterly winds in the Sacramento region, keeping pollutants dispersed and ozone levels Good. Saturday, sunny skies and temperatures in the upper-80s will enhance ozone formation in the Sacramento area. In addition, winds will become light in the afternoon, limiting pollutant dispersion. As a result, ozone levels will be Moderate.

Curious about Air Quality?
 
      AQI: Air Quality Index
      PM: Pariculate Matter
      PM2.5: size of the particle measured in micrometers
 
      Pm0.1 (Altra Fine Particles), PM2.5 (Fine Particles) and PM10 (Course Particles) are the 3 main sizes of particles.
      PM2.5 which incudes all sizes up to 2.5 is the most dangerous because it cause more damage to the lung than larger particules. When you cough or swallow your body is trying to get rid of particulate matter that has been trapped in your lung by mucous that was produced for that job. Tiny hairs move the mucous and particles out of the lungs to the back of the throat where you then will cough it out. Smaller particles however, cannot be moved out of the lungs but become trapped by special cells that keep them there. If these toxic particles do become trapped in the lungs, they can cause lung disease, lung cancer, emphysema, etc. Though the smaller particles may cause the most damage to the lungs, both PM2.5 and PM10 can cause a series of respiratory health problems (occurring within the lungs and airway). Due to the fact that PM2.5 is smaller and often much more toxic (metals and cancerous material) than PM10 it causes more damage to the lungs because it travels deeper.
 
PM10 (course Particules)
  • Smoke, Dirt, and Dust from Factories Farming and Roads
  • Molds, Spores, and Pollen
 PM2.5 (Fine Particules)
  • Toxic Organic Compounds (Such as Smog)
  • Heavy metals
These examples of PM2.5 are made by burning fossil fuels, fires, and smelting and processing metals.
 

Ground-level Ozone
 
      Definition: Ground—level ozone is ozone present as a secondary pollutant in the lower atmosphere, where its formation can be enhanced by other pollutants. It is highly toxic at levels above 0.1 parts per million (p.p.m.).
      Ground level Ozone:
Or Smog is located in the troposphere, or the air closest to the earths surface. Ground-level ozone has the same chemical structure as that of Ozone located higher in the atmosphere. Ground-level Ozone is an air pollutant that damages human health along with crops, trees and other vegitation. Ground-level ozone is formed when two types of pollutants react in the presence of sunlight. This Ozone is created chemically from many factors such as Motor Vehicle Exhaust and Industrial Emissions, Gasoline Vapors, as well as Natural Sources that omit NOx and VOC into the air. Sunlight and warm weather can cause harmfull concentrations in the air which is why Air Quality is particularly dangerous during summer months. The air we breathe is made up of Two oxygen atoms(O2) while Ozone is made up of three oxygen atoms(O3) making it increasingly dangerous to breathe. This is why it is important to monitor the air quality

      Stratosphere Ozone: This is Ozone located 6-30 miles up in the air in the stratosphere. This layer blocks harmful UV rays from reaching the earths surface. See UV radiation Page This is also known as "good Ozone"
