International audience it has been robustly demonstrated that variations in the circulation of the middle atmosphere influence weather and climate throughout the troposphere all the way to the earth’s surface. a key part of the coupling between the troposphere and stratosphere occurs through the propagation and breaking of planetary waves and gravity waves. limited observations of the middle atmosphere and these waves in particular hamper our ability to faithfully reproduce the dynamics of the middle atmosphere in numerical weather prediction and climate models.An exciting scientific development in recent years has been the potential for a number of novel ground-based measurement techniques to give new and complementary measurements of the middle atmosphere. the main challenge of the arise (atmospheric dynamics infrastructure in europe) project[1] is to combine for the first time existing national and international observation networks which observe the middle atmosphere including: the international infrasound monitoring system developed for the CtBt (Comprehensive nuclear-test-Ban treaty) verification, the NDACC (Network for the Detection of atmospheric Composition Changes) lidar network, localized european observation infrastructures at mid latitudes (OHp observatory), tropics (Maïdo observatory), high latitudes (alOMar and eisCat), infrasound stations developed at national level in european countries and satellite measurements. this joint network provided advanced data products, with the scope to assemble the derived upper atmospheric wind and temperatures into NWP models.the arise infrastructure is unique because of its coverage (from polar to equatorial and tropical regions in the european longitude sector and adjacent regions), its ability to sense a wide range of altitudes (including stratosphere, mesosphere, lower thermosphere, ionosphere) and the involved scales both in time (from seconds to tens of years) and space (from tens of meters to thousands of kilometers). We are about to embark upon a new ...
