Propagation of short-period gravity waves at high-latitudes during the MaCWAVE winter campaign
International audience As part of the MaCWAVE (Mountain and Convective Waves Ascending Vertically) winter campaign an all-sky monochromatic CCD imager has been used to investigate the properties of short-period mesospheric gravity waves at high northern latitudes. Sequential measurements of several...
