Для мобильных измерений разработан компактный спектрометр IBBCEAS с синим светодиодом (LED) с длиной волны 458 нм, полушириной 25 нм и полостью длиной 50 см. Предел обнаружения NO2 рассчитан как 1.9 части на миллиард по объему (ppbv) в течение 30 с сбора данных путем стабилизации спектра излучения светодиода, оптимизации эталонных сечений NO2 и калибровки отражательной способности зеркал резонатора. Точность спектрометра проверена путем измерения образцов NO2 с различными коэффициентами смешивания в диапазоне 1–200 ppbv, полученных с помощью системы разбавления газа в лаборатории. Наблюдения проведены во время трех отдельных маршрутов в Нанкин и прилегающие районы. Атмосферный NO2 вблизи земли измерен спектрометром с 4 по 7 августа 2013 г. Соотношение NO2 в смеси варьировалось от 3 до 144 ppbv. Результаты сопоставлены с плотностью NO2, измеренной прибором пассивной дифференциальной спектроскопии оптического поглощения (DOAS) на том же автомобиле. Продемонстрирована целесообразность использования спектрометра для автомобильных измерений атмосферного NO2. </p></abstract><trans-abstract xml:lang="en"><p>We report car-borne measurements of atmospheric NO2 close to the ground by incoherent broadband cavity enhanced absorption spectroscopy (IBBCEAS). A compact IBBCEAS spectrometer with a blue light emitting diode (LED) having a central wavelength of 458 nm, a full width at half maximum of 25 nm, and a 50-cm-long cavity was developed for mobile measurements. The NO2 detection limit of the spectrometer was calculated as 1.9 parts per billion by volume (ppbv) for a 30 s acquisition time by stabilizing the LED emitting spectrum, optimizing the NO2 reference cross-sections, and by calibrating the reflectivity of the cavity mirrors. The accuracy of the spectrometer was verified by measuring NO2 samples with various mixing ratios between 1–200 ppbv, which were produced by a gas dilution system in the laboratory. Three distinct journeys in Nanjing and the surrounding areas were selected as observation routes. The atmospheric NO2 close to the ground was measured by the spectrometer from August 4 to 7, 2013. The mixing ratios of NO2 ranged from 3 to 144 ppbv. These results were compared with the column density of NO2 measured by a passive differential optical absorption spectroscopy (DOAS) instrument on the same car. Hence, we demonstrate the feasibility of using the spectrometer for car-borne measurements of atmospheric NO2. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>некогерентная широкополосная спектроскопия усиленного поглощения</kwd><kwd>мобильные измерения</kwd><kwd>атмосферный NO2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>incoherent broadband cavity enhanced absorption spectroscopy</kwd><kwd>car-borne measurements</kwd><kwd>atmospheric NO2</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported in part by Anhui Province Key R&amp;D Program of China under Grant 202004i07020011, and in part by the National Natural Science Foundation of China under Grant 41305139, 41530644, 41775029, and 91644107.
