Aerosol measurements with shipborne sun-sky-lunar photometer and collocated multiwavelength Raman polarization lidar over the Atlantic Ocean

Aerosol measurements with shipborne sun-sky-lunar photometer and collocated multiwavelength Raman polarization lidar over the Atlantic Ocean

A shipborne sun-sky-lunar photometer was tested in two trans-Atlantic cruises aboard the German research vessel Polarstern from 54° N to 54° S. A full diurnal cycle of mixed dust-smoke episode measured with shipborne CE318-T is presented for the first time. Latitudinal distribution of AOD from the shipborne CE318-T, Raman lidar and MICROTOPS II shows the same trend with high values at 0 ~ 20° N dust transported belt and low values at Southern Hemisphere. Coefficient of determination for the linear regression between MICROTOPS II and shipborne sun-sky-lunar photometer was 0.993 for AOD at 500 nm and 0.896 for Ångström exponent at 440–870 nm.
