Inter-comparison of multisensory AOD products observed over East China during 2005-2018

Abstract

Atmospheric aerosols have received significant importance due to their impact on climate
change. The aerosol Optical Depth (AOD) has become more important in atmospheric science research, and
several researchers have done many studies on it in different regions of China and around the world. In this
paper, we have chosen six sites (Hangzhou, Jinan, Linan, Nanjing, Shanghai, and Shouxian) located in East
China to inter-compare the AOD retrieved from the Moderate-resolution imaging spectroradiometer
(MODIS) and Multi-angle Imaging SpectroRadiometer (MISR) satellites during 2005-2018. Besides AOD,
we also utilized to study on the Angstrom exponent measured at 470/660 nm overland (AE) and investigated
their relationship in identifying the aerosol types. Further, we identified the sources of aerosol emissions and
the transport pathways utilizing the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT)
model arriving at the observation sites during the study period
