A similar comparison for the transition from 1988 to 1989 in ERA-Interim reveals slightly larger differences below 10 hPa, in the region of the South Pole and near the equator. The differences in the mid to upper stratosphere (10 to 1 hPa) are similar to those in the 2009/2010 ERA5 transition, with a similar magnitude and concentrated at low latitudes. The , on the whole, differences of a similar magnitude. However, the exception to this is that the differences in the ERA-Interim transition in the lower to mid mesosphere (from 1 to 0.1 hPa, with the latter being the top of the ERA-Interim domain) are generally smaller than in the 2009/2010 ERA5 transition, having a magnitude magnitudes less than 2 K, except near the equator at about 0.8 hPa where the magnitudes exceed 3 K.
