Ozone Measurements -

OZONE MEASUREMENTS At altitudes of 35-45 km, there is reasonable agreement between the Stratospheric Aerosol and Gas Experiment II II (SAGE I/11), SBUV, and Urnkehr, that during 1979-1991, ozone declined 5-10% per decade at 30-50°N and slightly more at southern midlatitudes. In the tropics, SAGE IIII gives larger trends (ca. -10% per decade) than SBUV (ca. -5% per decade) at these …

Trends in Ozone Profile Measurements

A comparison of SAGE-1 and SBUV ozone measurements is presented for February 1979 through November 1981, and of SAGE–TI and SBUV ozone measurements for October 1984 through December 1986. The SBUV data were searched for those events nearly coincident in time and space to the SAGE-1 and –II events (Figure ). The working data for such coincidences were analyzed as time series in …

NASA Ozone Watch: Latest status of ozone

2021-07-27· The Dobson Unit (DU) is the unit of measure for total ozone. If you were to take all the ozone in a column of air stretching from the surface of the earth to space, and bring all that ozone to standard temperature (0 °Celsius) and pressure ( millibars, or one atmosphere, or “atm”), the column would be about centimeters thick. Thus, the total ozone would be atm-cm. To make ...

NASA | Ozone and Air Quality

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 being released into the atmosphere destroyed stratospheric ozone through a previously unrecognized catalytic reaction. In ...

Ground level ozone - Wikipedia

Measurement. Ozone in the atmosphere can be measured by remote sensing technology, or by in-situ monitoring technology. Because ozone absorbs light in the UV spectrum, the most common way to measure ozone is to measure how much of this light spectrum is absorbed in the atmosphere. Because the stratosphere has higher ozone concentration than the troposphere, it is important for remote …

Measuring ozone - aeroqual

Follow these guidelines to effectively monitor and measure ozone. Sensor height. Because ozone is heavier than air and tends to sink, concentration gradients are common in rooms and are greatly influenced by air movement and mixing. This means the detection of leaks from ozone-generating equipment should be performed at the most appropriate position for the application. Gas and vapor ...

ozone measurements at Uccle (Brussels, Belgium: 50 480N, 4 210E; ). We explain why the ozone-sounding programme was initiated more than 50 years ago and dis-cuss the presence of a period of gaps in the time series (Sect. ). We also describe which efforts have been under-taken during this time period to guarantee the homogeneity of the time series of ozonesondes between ascent and ...

Ozone Units of Measure - Ozone Solutions

The most common ozone measurement is ppm, and is used to measure ozone in air and ozone dissolved into water. ppb = Parts per Billion. This indicates the same thing as ppm, only change the million to a billion. This moves a decimal point 3 places. For example ppm = 100 ppb. mg/l = Milligrams of Ozone per Liter. Is a measurement of ...
