An award is made to the University of Minnesota to acquire an Enhanced Climate Change Simulator, a unique instrument that simultaneously creates and measures future conditions outdoors in central Minnesota grassland, without chambers or enclosures, with the specific objective of simulating the atmospheric chemistry (CO2 concentration, atmospheric N deposition) and climate (temperature and rainfall) of the future, and monitoring a set of ecosystem responses. The Simulator includes equipment that modifies CO2, temperature and rainfall; and ancillary equipment to monitor and control those environmental variables, and to monitor abiotic and biotic (vegetation and soil organisms) responses of the ecosystem to the climate simulation. The Simulator will contribute to comprehensive research training for University of Minnesota students and postdocs, serve as a research platform for a wide array of collaborative and cooperative researchers at University of Minnesota and at other institutions, provide STEM education and training to primary, secondary and post-secondary students and educators, and provide public outreach through multiple media. The Simulator will contribute to important societally relevant scientific research. Only a handful of climate change simulators with similar capabilities exist around the world, and none controls as many aspects of future climate, nor has as long a continuous record of ecosystem response. Notably, the simulator will uniquely enable hypothesis testing about interactive effects of multiple global change factors on grassland ecosystems. Such interactive effects remain one of the biggest gaps in understanding that hinder predictions of whether terrestrial ecosystems will be resilient in the face of multiple global changes and whether their responses to global change will slow or accelerate the pace of climate change.

明尼苏达大学获得了增强型气候变化模拟器，这是一种独特的仪器，可以同时创建和测量明尼苏达州中部草原户外的未来条件，没有室或围栏，其具体目标是模拟未来的大气化学（二氧化碳浓度，大气N沉降）和气候（温度和降雨），并监测一系列生态系统响应。模拟器包括调整二氧化碳、温度和降雨量的设备；以及辅助设备来监测和控制这些环境变量，并监测生态系统对气候模拟的非生物和生物（植被和土壤生物）反应。模拟器将为明尼苏达大学的学生和博士后提供全面的研究培训，为明尼苏达大学和其他机构的广泛合作和合作研究人员提供研究平台，为小学，中学和大专学生和教育工作者提供STEM教育和培训，并通过多种媒体提供公众宣传。模拟器将有助于重要的社会相关的科学研究。世界上只有少数几个具有类似能力的气候变化模拟器，没有一个能控制未来气候的许多方面，也没有一个能长期连续记录生态系统的反应。值得注意的是，该模拟器将独特地实现多种全球变化因子对草地生态系统相互作用的假设检验。这种相互作用仍然是认识上的最大差距之一，阻碍了陆地生态系统在面对多重全球变化时是否具有复原力以及它们对全球变化的反应是否会减缓或加速气候变化的步伐的预测。
