Correlative Dynamics Studies Using the Air Force Sodium Lidar and Associated Instrumentation at the ALOMAR Observatory
The present award was for correlative use of the Weber lidar (built and installed at ALOMAR under previous DURIP funding) for dynamics studies in the mesosphere, thermosphere, and ionosphere. Initial activities focused on expanded capabilities, frequency stability, and stable operations of the Weber...

The present award was for correlative use of the Weber lidar (built and installed at ALOMAR under previous DURIP funding) for dynamics studies in the mesosphere, thermosphere, and ionosphere.

Initial measurements demonstrated a dual-beam capability, off-vertical measurements of momentum fluxes, and full daytime operations. Efforts during 2002 and 2003 emphasized collaborative measurements in support of the MaCWAVE summer and winter rocket and ground-based measurement campaigns. Analyses of these results have revealed a highly active and variable summer mesopause environment, with large wave amplitudes, extreme temperature and wind gradients, and strong turbulence and mixing both above and below the mesopause.
