Short summary
We evalute four methods currently used for gravity wave extraction from lidar temperature measurements. The spectral response of these methods is determined with the help of synthetic temperature perturbations. Afterwards, the methods are applied to lidar temperature measurements over New Zealand for further evaluation of the four algorithms. Based on the results two methods are recommended for gravity wave extraction.
