Short summary

A study of trends in the middle stratosphere using comparisons of four main reanalyses (ERA-Interim, JRA-55, MERRA and NCEP/NCAR). We identified that all four reanalyses show very similar trends on a season or monthly basis. We also compute trends for each grid point not as a zonal mean. This approach shows detailed features in the trend studies in both hemispheres.
