Предложен метод оценки концентрации мелких твердых частиц PM2.5 с использованием лидаров, учитывающий сложности в их измерении. Путем расчета аэрозольной оптической глубины (AOD) для приборов MODIS, CALIPSO и наземного лидара предсказана скорректированная оценка PM2.5. Показано, что зависимость между AOD и PM2.5 линейная. При измерениях наземным лидаром коэффициент линейной корреляции между AOD и PM2.5 R = 0.81, среднеквадратичная ошибка RMSE = 24.43 и среднее отклонение MD = 18.41, для CALIPSO – R = 0.8, RMSE = 42.91 и MD = 33.25, для прибора VIIRS R  0.7. Результаты представляют возможности для лидарного наблюдения и прогнозирования окружающей среды. 

Due to the complications in the measurement of fine particulate matter (PM2.5), this paper proposes a method using lidar for assessing PM2.5. By calculating the aerosol optical depth (AOD) for MODIS, CALIPSO, and ground-based lidar, the corrected PM2.5 was predicted. The results showed that AOD and PM2.5 had a linear relationship. The linear correlation coefficient between ground-based lidar AOD and PM2.5 was 0.81, and the root mean square error (RMSE) and mean deviation (MD) were 24.43 and 18.41, respectively. The linear correlation coefficient between CALIPSO AOD and PM2.5 was 0.8, and its RMSE and MD were 42.91 and 33.25, respectively. The linear correlation between AOD and PM2.5 for VIIRS was approximately 0.7. This paper provides more possibilities for lidar observation and prediction of the environment
