Daily Soil Temperature and Meteorological Data for Sites at Toolik Lake Alaska, Version 1

This data set consists of daily air, water, and soil temperature, wind speed, vapor pressure, and the sum of global radiation and unfrozen precipitation data from the Toolik Lake area of Alaska between 1998 and 2002. The data includes readings from two sites: the Toolik Arctic Long Term Ecological Research (LTER) Tundra site and the nearby Toolik Tussock Experimental plots site that includes soil measurements from fertilized and unfertilized greenhouse and 'shadehouse' areas. Data loggers recorded soil temperatures at various intervals down to 150 cm. Air temperatures were recorded between 1 and 5 meters. The data consist of 28 comma-delimited ASCII text files, and are available via ftp. Data files for each site contain slightly different meteorological parameters. This data set is a subset of the more comprehensive data set, Monitoring and Manipulation of Tundra Response to Climate Change, Arctic LTER, Toolik Lake, Alaska. The research project was funded by the Arctic System Sciences (ARCSS) Program, grant number OPP-9810222.本数据集涵盖1998至2002年间美国阿拉斯加州图利克湖（Toolik Lake）区域的每日气温、水温、土壤温度、风速、水汽压，以及总全球辐射与未冻结降水数据。数据集包含两个采样站点的观测结果：图利克北极长期生态研究（Long Term Ecological Research，LTER）苔原站点，以及邻近的图利克草丛实验样地；该样地包含施肥组、未施肥组温室及‘遮阳棚’区域的土壤测量数据。 数据记录器以不同采样间隔对深度达150 cm的土壤温度进行采集；气温观测高度介于1至5米之间。本数据集包含28个以逗号分隔的ASCII文本文件，可通过文件传输协议（File Transfer Protocol，FTP）获取。各站点对应的数据文件包含略有差异的气象参数。本数据集为更全面的数据集《苔原对气候变化的响应监测与调控：阿拉斯加州图利克湖北极长期生态研究》的子集。 本研究项目由北极系统科学（Arctic System Sciences，ARCSS）计划资助，资助编号为OPP-9810222。
