Preliminary results of satellite and ground-based lidar observations for aerosol perturbations in Northern hemisphere stratosphere after Grimsvotn eruption, May 2011

摘要

In the report we present our study of volcano eruption products transportation in the Northern hemisphere stratosphere. In this investigation we use data from CALIPSO satellite and ground-based lidar at the Institute for automation and control processes. It is shown that most of aerosols are transported from north to medieval latitudes through polar and further subtropical jets. According to ground-based measurements it was found out that there was a permanent volcanogenic aerosol layer at the altitudes of 20 km from mid-June to mid-October, 2011.
