Summer gravity wave activity at 54°N observed by lidar and AIRS satellite measurements

The work presented here is an analysis of six years of gravity wave activity during the summer season at 54°N (Kühlungsborn, Germany) using Rayleigh Mie Raman (RMR) Lidar temperature measurements and NASA's Aqua satellite Atmospheric Infrared Sounder (AIRS) radiance measurements. The preliminary results of the analysis show short (~2 days long) bursts of gravity wave activity over this region in both the 4 μm and 15 μm high brightness temperature variances from AIRS. To complement this analysis, we used the 8.1 μm radiance measurements to detect convection in the area, as well as ECMWF for the meridional and zonal wind speed. Also, we investigated the presence of these summer maxima in the RMR Lidar data. Additionally, a comparison of lidar and AIRS retrieval temperature profiles will be discussed. Using this combination of instruments, while taking into account their observation filter, could improve our understanding of the gravity wave properties.
