Research Abstract

This study aims to continue and develop the aerosol lidar network throughout Argentina and Chile and ozone hole prediction and observations at the southern tip of the South American continent, established in the SAVER-Net project ended in March 2108. The project could not proceed as planned mainly due to the COVID19 pandemic. But a small, portable, maintenance-free lidar that can be operated by local researchers only was developed for the network, paving the way for long-term and steady ground-based validation for the EarthCARE satellite. For ozone hole, although observations were far behind the original plan and sufficient data could not be obtained, the development of the forecasting model proceeded smoothly. Through the evaluation of the prediction scores, the parameters of the initial conditions were brushed up, making it possible to predict the ozone hole two to three weeks before it occurs.
