Science Update: A simple procedure for removing temporal discontinuities in ERA-interim upper stratospheric temperatures

C. McLandress and co-authors describe a simple procedure for removing unphysical temporal discontinuities in ERA-interim temperatures form 5-1hPa, which have arisen due to changes in the satellite radiance data used in the assimilation process. Adjustments to global mean temperatures are derived that can be applied to chemistry-climate models nudged to the ERA-interim reanalysis. Simulations using the CMAM model indicate that the inclusion of these adjustments produces a temperature time series without large jumps in the upper stratosphere. The full abstract can be found here.
