Short summary

The atmosphere hosts a multitude of waves, among which Atmospheric Gravity wave separation from satellite measurements requires removal of global scale waves and tides. The present study describes the open access software GLOFI (GLObal wave FIt) which uses the 2D spectral decomposition to perform this removal. It is validated on simulated temperature observations synthesised for ESA (European Space Agency) Earth Explorer 11 candidate CAIRT (Changing-Atmosphere Infra-Red Tomography Explorer).
