Abstract

A option of the methodology for observing PM_2.5 and PM₁₀ particle mass concentrations based on an Arduino UNO board and Sensirion SPS30 laser sensor has been developed. The measuring system built according to the technique was used in a field experiment, as well as in continuous observations at a stationary point: the Moscow Geophysical Monitoring Center of the Institute of Dynamics of Geospheres, Russian Academy of Sciences (IDG RAS). Examples of variations in the observed characteristics are given, which indicate the possibility of using the instrumental system in addition to already existing devices when observing the geophysical environment. Continuous monitoring of microparticle concentrations at the Geophysical Monitoring Center will make it possible not only to assess the degree of atmospheric pollution in the megalopolis, but also highlight certain trends, frequencies, and patterns. Such monitoring will also make it possible to reveal the contribution of various sources to the increase in microparticle concentrations, as well as the effect of pollution on different geophysical fields.

用于测量空气中微粒子浓度的紧凑型激光设备及其在俄罗斯科学院萨多夫斯基地球大气动力学研究所地球物理监测中心的应用

基于 Arduino UNO 板和 Sensirion SPS30 激光传感器的 PM2.5 和 PM10 粒子质量浓度观测方法选项已经开发完成。根据该技术建立的测量系统被用于现场实验，以及在一个固定点（俄罗斯科学院地球大气动力学研究所莫斯科地球物理监测中心）进行连续观测。文中举例说明了观测到的特征变化，这表明在观测地球物理环境时，除了现有的设备外，还可以使用该仪器系统。在地球物理监测中心对微粒子浓度进行连续监测，不仅可以评估大城市的大气污染程度，还可以突出某些趋势、频率和模式。这种监测还可以揭示各种来源对微粒子浓度增加的影响，以及污染对不同地球物理领域的影响。

期刊介绍： Seismic Instruments is a journal devoted to the description of geophysical instruments used in seismic research. In addition to covering the actual instruments for registering seismic waves, substantial room is devoted to solving instrumental-methodological problems of geophysical monitoring, applying various methods that are used to search for earthquake precursors, to studying earthquake nucleation processes and to monitoring natural and technogenous processes. The description of the construction, working elements, and technical characteristics of the instruments, as well as some results of implementation of the instruments and interpretation of the results are given. Attention is paid to seismic monitoring data and earthquake catalog quality Analysis.
