作者研究了纬度和生活史对北方半球中高纬度森林中卫星测量的归一化植被指数（NDVI）和地面测量的树木年轮宽度之间关系的影响。结果表明，在整个生长季节的所有地区分析的NDVI和树木年轮之间的相关性。对于40°N以南的站点，相关性出现在早春和晚秋，而相关性出现在40°N以北的夏季月份。对于针叶树，相关性出现在夏季，而落叶树显示，
The authors examine the effects of latitude and life history on the timing of relationships between satellite measures of normalized difference vegetation index (NDVI) and ground-based measures of tree-ring width in forests at mid- and high latitudes in the Northern Hemisphere. Results indicate a correlation between NDVI and tree rings over the entire growing season for all areas analyzed. For sites south of 40°N, a correlation appears in early spring and late fall while a correlation appears during summer months north of 40°N. For conifers, the correlation appears in summer while deciduous trees show the
