SUMO Chamber Conditions

The Los Alamos Survival–Mortality experiment (SUMO) is located on Frijoles Mesa near Los Alamos, New Mexico, USA, at an elevation of 2150 m. This was a tree manipulation study that investigated the relative impacts of drought and warming on plant function and reveals how trees adapt to drought and heat in semi-arid regions. The study factored the role of tree hydraulic acclimation to both precipitation and temperature and separated their effects.The experiment is located in a pinon-juniper woodland near the ponderosa pine (Pinus ponderosa) forest ecotone. Chamber conditions (temperature, relative humidity, vapor pressure deficit) for SUMO Open Top Chambers (OTCs) used to control air temperatures surrounding heated and control chamber trees. See SUMO Target Tree Information data package (doi:10.15485/1440544) for additional information. Data released by Los Alamos National Lab for public use under LA-UR-18-23656.

洛斯阿拉莫斯存活-死亡率实验（Los Alamos Survival–Mortality experiment，简称SUMO）坐落于美国新墨西哥州洛斯阿拉莫斯附近的弗里霍尔斯台地（Frijoles Mesa），海拔高度为2150米。本研究属于林木操控类实验，旨在探究干旱与升温对植物功能的相对影响，揭示半干旱区域树木适应干旱与高温的内在机制。该实验考量了树木水力适应性对降水与温度的响应，并区分了二者的独立调控效应。实验区域设于美国黄松（Pinus ponderosa）林交错带附近的矮松-杜松林地中。实验中采用SUMO开顶式气室（Open Top Chambers，简称OTCs）对处理组与对照组树木周边的空气温度进行调控，该气室的环境监测参数涵盖温度、相对湿度与水汽压亏缺。更多详细信息可查阅《SUMO目标树木信息》数据包（DOI:10.15485/1440544）。本数据集由洛斯阿拉莫斯国家实验室发布，依据LA-UR-18-23656许可协议面向公众开放使用。
