Simultaneous Use of Ground-Based and Satellite Observation to Evaluate Atmospheric Air Pollution over Amman, Jordan

In this study, a combination of ground-based particulate matter measurements in synergy with space-borne CALIOP lidar recordings, meteorological observations, and reanalysis models have been used to study atmospheric air pollution over Amman, Jordan. The measurement was conducted 24-month period spanning from January 2018 the end December 2019. aerosol profiles layer products version 4.21, level 2, 5 km horizontal resolution were evaluate vertical structure constituent Amman region. particle depolarization ratio (PDR) extracted recordings has utilized classify type aerosols. This method reveals that atmosphere above mostly contains three different types including coarse-mode dust, fine-mode dust (polluted dust), non-dust aerosols (pollution). Aerosols 0 < δp≤ 0.075 are categorized as pollution, 0.20 polluted 0.40 classified dust. Both one- two-step POlarization-LIdar PHOtometer Networking (POLIPHON) approaches applied profile product retrieve optical micro-physical properties each type.
