Inertia gravity waves in the upper troposphere during the MaCWAVE winter campaign ? Part I: Observations with collocated radars
International audience During the {MaCWAVE} campaign, combined rocket, radiosonde and ground-based measurements have been performed at the Norwegian Andøya Rocket Range (ARR) near Andenes and the Swedish Rocket Range (ESRANGE) near Kiruna in January 2003 to study gravity waves in the vicinity of the...
