ECHAM6 atmospheric model data for experiments with an artificial snow anomaly added over Eurasia. ECHAM6 resolution was T63L95. Variables include: temperature, u winds, geopotential height, snow fraction. Atmospheric data is on 24 levels from 1000hPa to 1hPa. Monthly time-means Python notebooks are included to replicate all figures from Tyrrell, N. L., A. Y. Karpechko, and P. Räisänen, 2018: The influence of Eurasian snow extent on the northern extratropical stratosphere in a QBO resolving model. J. Geophys. Res., 123, 315–328 Tyrrelletal2018_clim.tar.gz contains the control runs. Tyrrelletal2018_snow.tar.gz contains the snow anomaly runs. Both tar files contain the python notebooks
