It has been suggested that maximum latewood density (MXD) should be used instead of tree-ring width (TRW) data to reconstruct post-volcanic cooling effects. A thorough assessment of high frequency signals and potentially differing memory effects in long MXD and TRW chronologies, in response to large volcanic eruptions, is still missing, however. We here present a compilation of MXD and TRW chronologies...
Key MessageIn the Pyrenees low temperature and scarce precipitation limit radial growth at treeline.The climatic drivers of treeline formation in mid-latitude mountains are temperature and also moisture variability. Abstract Alpine treelines are often induced by a threshold of minimum temperatures above which tree growth is generally not possible anymore. However, this worldwide pattern may...
