Precipitation variation since 1748 CE in the central Lesser Khingan Mountains, Northeast China

Inter-annual variations of precipitation play important roles in forest management and agricultural production. This study presents a 270-year precipitation reconstruction of winter to early growing season for the central Lesser Khingan Mountains, Northeast China based on tree-ring width data of 99...
