CAMEX-4 DUAL-BEAM UV-ABSORPTION OZONE PHOTOMETER V1

The CAMEX-4 Dual-Beam UV-Absorption Ozone Photometer dataset was measured by using a photometer consisting of a mercury lamp, two sample chambers that could be peridically scrubbed of ozone, and two detectors that measured the 254-nm radiation transmitted through the chamber from the lamp. The ozone number density was calculated using the ozone absorption cross-section at 254nm and the Beer-Lambert Law. The one second data collection rate at the minimum detectable concentration of ozone (one sigma) was 1.5 x 1010 molecules/cm3.

CAMEX-4 双束紫外线吸收臭氧光度计数据集由一台包含汞灯、两个可周期性清除臭氧的样品室以及两个测量从灯泡穿过样品室的254纳米辐射的探测器组成的光度计测量得出。臭氧数密度是通过254纳米处的臭氧吸收截面以及比尔-朗伯定律进行计算的。在臭氧最小可检测浓度（一个标准差）下，数据收集速率为每秒1.5 x 10^10 分子/立方厘米。
