Scientific problems and solutions for measuring aerosol concentrations in the atmosphere: taking into account metrological requirements

This paper addresses the scientific challenges associated with measuring aerosol concentrations in the atmosphere, focusing on compliance with metrological standards. The analysis covers factors influencing measurement accuracy and reproducibility, such as uncertainty, instrument calibration, and methodological selection. The limitations posed by incomplete a priori information and their impact on decision-making reliability are examined. The study proposes methodological improvements for measurement procedures and data processing, aiming to enhance reliability under variable atmospheric conditions. Prospects for advancing metrological support, including the development of new calibration devices and adherence to international standards, are discussed. The influence of regulatory requirements on the quality of aerosol monitoring is highlighted, and the integration of high-precision measurement technologies into automated systems is identified as a promising direction for future research and practical application.
