Оценка достоверности мониторинга аэрозольных загрязнений в атмосфере путем сравнения результатов обработки данных лидарного зондирования и локального забора проб

Abstract

Data measured with remote (lidar) sensing and in situ during ORACLES campaign in 2016 became publically accessible. Inversion of the data measured with lidar and including the aerosol backscatter coefficients at 355, 532 and 1064 nm and extinction coefficients at 355 and 532 nm is carried out in the study. Airborne high spectral resolution lidar was used in the measurements. Specially developed regularization algorithm is applied to invert the lidar data into aerosol optical and microphysical parameters. In frame of ORACLES campaign the aerosol optical and microphysical parameters were measured in situ as well. In situ and remote (lidar) measurements were spatially and temporarily co-located. In situ results are used to validate the inversion of lidar data with regularization algorithm. Uncertainties of 25% for effective radius, number and volume concentrations, 0.05 and 0.005 for real and imaginary parts of complex refractive index respectively and 0.05 for single scattering albedo are validated with reliability 90%.
