对物候变化的观察为气候变化对陆地生态系统的影响提供了一些最强烈的信号。国际冻土带实验(ITEX)于20世纪90年代初启动，建立了一个共同的方案来测量全球冻土带研究地区的植物物候。今天，这一宝贵的物候学测量集合描绘了过去几十年来地球上较冷极端的植物对实验和环境温度变化的反应。该数据库包含了在28个研究区域进行的278个植物物种的150至434个物候观测，时间跨度为1-26年。在这里，我们描述了完整的数据集，以提高这些数据在全球分析中的可见性和使用率，并邀请未被充分代表的冻土带地区提供物候数据。冻土带物候数据库的一部分已经用于最近的三次合成，一些数据集被扩展，另一些来自全新的研究领域，这些数据的全部现在可以在极地数据目录(https://doi.org/10.21963/13215).)中获得
Observations of changes in phenology have provided some of the strongest signals of the effects of climate change on terrestrial ecosystems. The International Tundra Experiment (ITEX), initiated in the early 1990s, established a common protocol to measure plant phenology in tundra study areas across the globe. Today, this valuable collection of phenology measurements depicts the responses of plants at the colder extremes of our planet to experimental and ambient changes in temperature over the past decades. The database contains 150 434 phenology observations of 278 plant species taken at 28 study areas for periods of 1–26 years. Here we describe the full data set to increase the visibility and use of these data in global analyses and to invite phenology data contributions from underrepresented tundra locations. Portions of this tundra phenology database have been used in three recent syntheses, some data sets are expanded, others are from entirely new study areas, and the entirety of these data are now available at the Polar Data Catalogue (https://doi.org/10.21963/13215).
