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.

本数据集收录了1998年至2002年间阿拉斯加州图利克湖（Toolik Lake）区域的每日空气温度、水体温度、土壤温度、风速、水汽压，以及总全球辐射与未冻结降水数据。数据集涵盖两个采样站点的观测数据：图利克北极长期生态研究（Arctic Long Term Ecological Research, LTER）苔原站点，以及邻近的图利克草丛（Toolik Tussock）实验样地；后者包含施肥组、未施肥组温室及“荫棚”区域的土壤测量数据。

数据记录仪以不同采样间隔对深度达150厘米的土壤温度进行记录；空气温度的观测高度介于1米至5米之间。本数据集包含28个逗号分隔的ASCII文本文件，可通过FTP获取。两个站点的数据文件所包含的气象参数略有差异。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》（Monitoring and Manipulation of Tundra Response to Climate Change, Arctic LTER, Toolik Lake, Alaska）的子集。
