Multistatic meteor radar networks have become a valuable tool to study the spatial and temporal variability of mesosphere/lower thermosphere winds. Combined with advanced and tomographic analysis such as the 3DVAR+DIV or VVP algorithm it is possible to infer spectral information related to the horizontal wavelength and the temporal spectrum. Here we present a statistical analysis of almost 5 years of observations recorded with the Nordic Meteor Radar Cluster and CONDOR. Our initial results show a seasonal variability of the spectral slopes for different spatial scales indicating a reduced gravity wave activity during the spring for the Northern hemispheric data. Furthermore, we find a transition from a k-3 to a k-5/3 slope for spatial scales around 150 kilometers. Zonal wavelength spectra at CONDOR exhibit a less clear seasonal pattern compared to the Nordic Meteor Radar Cluster.
