The middle and upper atmosphere is a highly variable environment at subseasonal time scales. This variability influences the general atmospheric circulation especially through the propagation and breaking of planetary and gravity waves in the stratosphere and mesosphere. The ARISE (Atmospheric dynamics Research InfraStructure in Europe) project integrates complementary instruments such as infrasound stations of the International Monitoring System developed for the verification of the Comprehensive nuclear-Test-Ban-treaty, lidar and radar networks and satellites. One main objective is to determine the origin of the uncertainties in Numerical Weather Prediction (NWP) models, such as the operational analyses distributed by the European Centre for Medium-Range Weather Forecasts (ECMWF). Another application is the monitoring of extreme events such as volcanoes and other weather related events. This presentation will review main ARISE results and challenging perspectives for the development of an european research infrastructure dedicated to the study of the dynamics in broad time and space scales from near ground to near space.
