NASA | Ozone and Air Quality

NASA's Ozone and Air Quality site provides data and results from Backscattering Ultraviolet (BUV) satellite sensors. These sensors are used to measure and monitor atmospheric trace gases (such as ozone, SO2, and NO2), aerosols, surface reflectance, and cloud pressure. Over 30 years ago, the first BUV instruments provided measurements that were integral to the discovery that man-made CFCs …

Ozone Measurement Units & Techniques | Spartan

A unit of measurement in the gas phase grams of ozone per normal cubic meter usually written as g/Nm3. The term “normal” in this expression is critical since gas density is influenced by pressure. Normal in this case refers to the the conditions at which the measurement was taken, or the condition to which it has been adjusted.

How to Measure Air Pollutants? | Air Pollution

The chemiluminescent reaction is that between ozone and ethylene. Chemiluminescence from this reaction occurs over a range of 300-6000 nm, with a maximum at 435 nm. The intensity of emitted light is directly proportional to the level of ozone. Ozone concentrations ranging from to 30 ppm may be measured.

Q5: How is ozone measured in the atmosphere?

Some instruments measure ozone locally in sampled air and others measure ozone remotely some distance away from the instrument. Instruments use optical techniques, with the Sun and lasers as light sources, or use chemical reactions that are unique to ozone. Measurements at many locations over the globe are made regularly to monitor total ozone amounts. Q5: How is ozone measured in the …

KMI - Measuring ozone

Local measurements of the atmospheric abundance of ozone are those that require air to be drawn directly into an instrument. Once inside an instrument’s detection chamber, the amount of ozone is determined by measuring the absorption of ultraviolet (UV) light or by the electrical current or light produced in a chemical reaction involving ozone. The last approach is used in “ozonesondes”, …

How Is Air Quality Measured? | NOAA SciJinks – All About Weather

09/07/2021· Air quality is a measure of how clean or polluted the air is. Monitoring air quality is important because polluted air can be bad for our health—and the health of the environment. Air quality is measured with the Air Quality Index, or AQI. The AQI works sort of like a thermometer that runs from 0 to 500 degrees. However, instead of showing changes in the temperature, the AQI is a way of …
