Continuous increase in evaporative demand shortened the growing season of European ecosystems in the last decade

<strong>Datasets provided above are processed data during the conducting analysis for our paper entitled "Continuous increase in evaporative demand shortened the growing season of European ecosystems in the last decade". </strong> <strong>Here is the abstract of the paper: </strong> <strong>Despite previous reports on European growing seasons lengthening due to global warming, evidence shows that this trend has been reversing in the past decade due to increased transpiration needs. We used an innovative method along with space-based observations to determine the timing of greening and dormancy and then to determine existing trends and causes. Early greening still occurs, albeit at slower rates than before. However, a recent (2011-2020) shift in the timing of dormancy has caused the season length to decrease back to 1980s levels. This shortening of season length is attributed primarily to higher atmospheric water demand in summer that suppresses transpiration even for soil moisture levels as of previous years. Transpiration suppression implies that vegetation is unable to meet the high transpiration needs. Our results have implications for future management of European ecosystems (e.g., net carbon balance and water and energy exchange with atmosphere) in a warmer world.</strong>上文提供的数据集，是为论文《近十年蒸发需求（evaporative demand）持续升高缩短了欧洲生态系统生长季》开展分析过程中所处理得到的数据。以下为本论文的摘要：尽管既往研究指出全球变暖可使欧洲地区生长季延长，但新近证据表明，近十年来该趋势因蒸腾需求攀升已出现逆转。本研究采用创新方法结合星载观测（space-based observations）数据，确定植被返青期与休眠期的时间节点，进而分析其变化趋势及成因。当前植被返青仍呈提前态势，但速率较此前有所放缓。然而，2011-2020年期间出现的休眠时间偏移，使得生长季长度回落至20世纪80年代的水平。生长季缩短主要归因于夏季大气需水量升高，即便土壤湿度维持在往年水平，仍会抑制蒸腾作用（transpiration）。蒸腾受抑意味着植被无法满足高蒸腾需求。本研究结果对于未来变暖背景下欧洲生态系统的管理（如净碳平衡、与大气间的水热交换等）具有重要参考意义。
