• Some grid boxes (around Greenland and Antarctica) snow continually accumulates during the entire simulations, reaching very large values. I think this is because the model does not represent calving of glaciers. These grid boxes should probably just be ignored, and certainly should be removed from global-mean snow cover for instance. (They have not been removed from the area-average series included on the SO&P website, which is why those series show a continual upward trend in mean snow cover.)
