This dataset provides daily and zonal mean variables derived from the MERRA-2 reanalysis, including terms of the transformed Eulerian mean (TEM) momentum budget. All variables (zonal, meridional and vertical wind speed, temperature, zonal wind tendencies from Eliassen-Palm (EP) flux divergence and advection, EP fluxes and the residual streamfunction) are obtained from 6-hourly and native vertical and spatial resolution data of the 'Assimilated' (ASM, M2I3NVASM) collection. Zonal mean wind tendency from gravity wave drag is also provided, obtained from the M2T3NPUDT collection. Data are provided as one .zip file per decade (only partial for the 2020s). Monthly means of the same quantities are provided in a companion dataset. The data and related documentation are provided 'as is' and without any warranty of any kind. Users are invited to report any issue or inconsistency they may find. Please cite the reference publication when using this dataset. Known issues: - All TEM terms divided by \(cos(\phi)\) diverge at the north and south poles (where \(\phi = \pm \pi/2\)), so they should not be considered. If variables at the poles are needed, values at neighbouring latitudes should be taken.
