Abstract

Observations of the instrument SEVIRI (Spinning Enhanced Visible and Infra-Red Imager) onboard the geostationary orbit Meteosat-8 were analyzed to study the diurnal behaviour, length and lifetime of so-called ship tracks near the west coast of southern Africa. Several days of data between May and November 2004 from the SEVIRI 3.9 µm-channel were used to analyse the characteristics of more than 230 ship tracks by visual analysis. The results show a diurnal variation with maximum occurrence around 10 am. The length and lifetime of the 230 ship tracks shows significant variation: the mean lifetime detected by means of the visibility in the 3.9 µm channel, was 18 h (± 11 h), but lifetimes up to 60 h have also been observed. The mean observed length is 458 km (± 317 km), with an observed maximum of 1500 km, showing a high dependence on wind direction in the region of interest. To take into account the high variations of the examined variables, we also present distribution functions for the length and the lifetime of ship tracks. The distribution functions can be used to improve estimates of radiative forcing from polar orbiting satellites and for parameterisations of sub-grid scale processes in global model simulations.
