Ozone level today

Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone. Click any map image to bring up a new page with a high-resolution image. OZONE AND PARTICLE POLLUTION. The maps show the higher of the estimated ozone AQI and PM2. A caret (^) indicates that levels of PM may exceed the applicable short-term NAAQS.

For more information see the following TCEQ websites:Air Pollution from Particulate Matter and Voluntary Tips for Citizens and Business to Reduce Emissions. Ground- level ozone is one of our nation’s most common air pollutants. Air Quality Guide for Ozone. Use the chart below to help reduce your exposure and protect your health.

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. Moderate conditions are most likely within the Denver Metro Area and extending northward in to southern and western Weld County, including Greeley. What is the acceptable level of ozone? What can you do to reduce ozone level?

What are the effects of high ozone levels? NASA provides daily images, data, and information from satellite instruments that monitor the ozone layer and the ozone hole, a thinning break in the stratospheric ozone layer. Designation of amount of such depletion as an ozone hole is made when the detected amount of depletion exceeds fifty percent. Current Ozone 1-Hour Levels. The map below shows the current highest ozone 1-hour levels measured in parts per billion (ppb) for each of the metropolitan or other areas across Texas where ozone is measured by the TCEQ.

Learn more about ground- level ozone. Ozone depletion may be a common news story, but many forget about the dangerous formation of ozone at ground level. Program is about ozone at ground- level - unhealthy to breathe, outdoor air pollution.

An unusual number of people this summer are making. Start studying Ozone depletion. Air quality monitors measure concentrations of ozone throughout the country.

EPA, state, tribal and local agencies use that data to ensure that ozone is at levels that protect public health and the environment. Ozone (O3) is composed of three oxygen atoms. It is not usually emitted directly into the air, but at ground level is created by a chemical reaction between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of heat and sunlight. Ozone is a highly unstable and reactive compound.

When ozone forms faster than it can break down, levels become high. Ozone levels can become high at any time, but ozone forms faster with warm temperatures, especially when summer days are hot, sunny, stifling, with little wind. Ozone can reach unhealthy levels on hot, sunny days in regions with high concentrations of the nitrogen oxides and VOC precursors, such as urban areas. Ozone and its precursors can also be transported long distances by win so even rural areas can experience high ozone levels (). At this level , it is a harmful air pollutant.

Unfortunately it will also feature poor air quality. Today is an Ozone Action Day due to the ozone levels in the.
