TLDR
Examples of ozone profiles measured, and intercomparisons with measurements made by other instruments are presented which show that the lidar, in its present configuration, is capable of producing high quality ozone measurements from 20 km up to at least 45 km.Abstract:
A ground-based differential absorption lidar system has been implemented to make long-term, precise measurements of stratospheric ozone concentration profiles from about 20 to 50 km altitude. This lidar is located at an elevation of 2300 m in the San Gabriel Mountains, Southern California, and has been in operation since January 1988. A high power (100-W) excimer laser system and a 90-cm diam telescope are used to achieve the desired performance levels. This paper describes the implementation of the system and its operation including the procedures for data analysis. Examples of ozone profiles measured, and intercomparisons with measurements made by other instruments, are presented which show that the lidar, in its present configuration, is capable of producing high quality ozone measurements from 20 km up to at least 45 km.read more

TL;DR: In this paper, the vertical distribution of ozone is reported and compared for a number of new and recently revised data sets, and the authors examine the periods before and after the peak to see if any change in trend is discernible in the ozone record that might be attributable to a change in the EESC trend, though no attribution is attempted.

TL;DR: In this article, the authors make a systematic assessment of fourteen limb and occultation sounders that, together, provide more than three decades of global ozone profile measurements, and they find that between 20-40 km, the satellite ozone measurement biases are smaller than ±5 %, the short-term variabilities are better than 5-12 % and the drifts are at most ±5 percent decade−1 (and ±3 % decade− 1 for a few records).

Ground‐based microwave monitoring of stratospheric ozone
TL;DR: A microwave instrument developed for operational measurements of ozone for the Network for Detection of Stratospheric Change is discussed in this paper, which observes two spectral lines near 3-mm wavelength with a bandwidth of 630 MHz, allowing profile retrieval from 20 to 70 km.

Large losses of total ozone in Antarctica reveal seasonal ClOx/NOx interaction
TL;DR: In this article, it was shown that the very low temperatures which prevail from midwinter until several weeks after the spring equinox make the Antarctic stratosphere uniquely sensitive to growth of inorganic chlorine, ClX, primarily by the effect of this growth on the NO2/NO ratio.
