摘要

The dynamical and physical parameters of polar mesosphere summer echoes (PMSE) and noctilucent clouds (NLC) have been studied using coordinated rocket, radar, and lidar experiments (ALWIN MST radar, ALOMAR MF radar and ALOMAR RMR lidar) during the MIDAS/DROPPS/Mini-DUSTY campaign. A strong, long lasting PMSE event connected with a weak NLC was present during the first salvo on July 5/6, 1999. The ALWIN MST radar (53.5 MHz) has performed spaced antenna measurements and Doppler beam steering observations using nine beam directions (vertical beam and oblique beams in northwest, southeast, northeast, and southwest direction at 7° and 14° off-zenith). For the first time radar observations were possible along rocket trajectories in northwest direction with intersections at altitudes between 75 and 90 km allowing common-volume observations on upleg and downleg. The obtained PMSE characteristics are discussed with particular emphasis to the times of rocket soundings. These parameters are signal power, aspect sensitivity, spectral width as well as horizontal winds.
