Comparison of OPTAIR aerosol counts and meteorological data. (a) Time series of attenuated backscatter profiles sampled by IAMCO (Italian Antarctic Meteo-Climatological Observatory) Vaisala CL51 Ceilometer (filled contour, bottom and left scales). The black line represents the time series of OPTAIR counts on an hourly basis; regions shown in white correspond to missing values. The coloured line above shows the cloud cover as calculated by the Vaisala CL51 Sky Condition algorithm (clear sky/few clouds in light cyan, scattered in dark green, broken in red and overcast in black). (b) Time series of ECMWF ERA5 Vertical Velocity (filled contour) and ECMWF ERA5 Total Precipitation (blue lines). The coloured line shows Wind Direction between 0° and 120° (dark violet), between 150° and 240° (gold), and between 270° and 330° (violet), corresponding to subset associated to the major events revealed by SPES. Wind measurements at a height of 3 m were obtained from the AWS (operated by IAMCO). Green dashed lines highlight the aerosol spikes revealed by SPES.
