“…The measurement of its concentration in the atmosphere relies on an accurate knowledge of its absorption cross sections. Several measurements have been performed in order to determine this spectroscopic quantity under various temperature and pressure conditions [1][2][3][4][5][6][7][8][9][10][11][12]. The temperature dependence of the NO 2 absorption cross sections is of major importance.…”

The measurements of the NO 2 absorption cross sections by several authors have been considered in order to derive its temperature and pressure dependences in the 13 200 -42 000 cm −1 spectral range. The temperature dependence is assumed to be linear in the temperature range investigated (217.0 -298:5 K), whereas the in uence of the total pressure is expressed as a temperature-dependent broadening coe cient. From measurements performed with mixtures of NO 2 in air and in N 2 , values of 0 air (296 K) and 0 N2 (296 K) were found to be, respectively, 0:081 ± 0:002 and 0:069 ± 0:003 cm −1 atm −1 . The temperature coe cient n obtained in the present work is 0:8 ± 0:1. The parameterization of the cross sections developed in this work can reproduce measured cross sections within 4%. ?

Two instruments based on differential optical absorption spectroscopy (DOAS) to measure accurate ammonia concentrations in the atmosphere

et al. 2012

Abstract. We present two Differential Optical Absorption Spectroscopy (DOAS) instruments built at RIVM: the RIVM DOAS and the miniDOAS. Both instruments provide virtually interference-free measurements of NH 3 concentrations in the atmosphere, since they measure over an open path, without suffering from inlet problems or interference problems by ammonium aerosols dissociating on tubes or filters. They measure concentrations up to at least 200 µg m −3 , have a fast response, low maintenance demands, and a high uptime. The RIVM DOAS has a high accuracy of typically 0.15 µg m −3 for ammonia for 5-min averages and over a total light path of 100 m. The miniDOAS has been developed for application in measurement networks such as the Dutch National Air Quality Monitoring Network (LML). Compared to the RIVM DOAS it has a similar accuracy, but is significantly reduced in size, costs, and handling complexity. The RIVM DOAS and miniDOAS results showed excellent agreement (R 2 = 0.996) during a field measurement campaign in Vredepeel, the Netherlands. This measurement site is located in an agricultural area and is characterized by highly variable, but on average high ammonia concentrations in the air. The RIVM-DOAS and miniDOAS results were compared to the results of the AMOR instrument, a continuous-flow wet denuder system, which is currently used in the LML. Averaged over longer time spans of typically a day, the (mini)DOAS and AMOR results agree reasonably well, although an offset of the AMOR values compared to the (mini)DOAS results exists. On short time scales, the (mini)DOAS shows a faster response and does not show the memory effects due to inlet tubing and transport of absorption fluids encountered by the AMOR. Due to its high accuracy, high uptime, low maintenance and its open path, the (mini)DOAS shows a good potential for flux measurements by using two (or more) systems in a gradient set-up and applying the aerodynamic gradient technique.
