GLOBAL SOIL TYPES, 1-DEGREE GRID (ZOBLER)

A global data set of soil types is available at 1-degree latitude by 1-degree longitude resolution. There are 26 soil units based on Zobler?s assessment of FAO Soil Units (Zobler, 1986). The data set was compiled as part of an effort to improve modeling of the hydrologic cycle portion of global climate models. A more extensive version of these data, including 106 soil units as well as soil texture and slope, is available from NCAR, Scientific Computing Division, Data Support Section; the more extensive data set is entitled "Staub and Rosenweig's GISS Soil & Sfc Slope, 1-Deg" [http://www.dss.ucar.edu/datasets/ds770.0/]. A help file prepared by Matthews and Fung (1987) (soil1x1.help) is provided as a companion file. Image of 26 soil types available at 1-degree by 1-degree resolution. Additional documentation from Zobler?s assessment of FAO soil units is available from the NASA Center for Scientific Information

本数据集提供全球1度纬度×1度经度分辨率的土壤类型数据，其分类基于佐布勒（Zobler）针对联合国粮食及农业组织（Food and Agriculture Organization of the United Nations, FAO）土壤单元开展的评估研究（Zobler, 1986），共包含26个土壤单元。本数据集的编制旨在改进全球气候模型中水文循环部分的模拟效果。
该数据集的扩充版本包含106个土壤单元，额外提供土壤质地与坡度信息，可从美国国家大气研究中心（National Center for Atmospheric Research, NCAR）科学计算部数据支持组获取；该扩充数据集的名称为"Staub and Rosenweig's GISS Soil & Sfc Slope, 1-Deg"，访问链接为[http://www.dss.ucar.edu/datasets/ds770.0/]。
随数据集附带由Matthews与Fung（1987）编制的辅助说明文件soil1x1.help。1度×1度分辨率的26类土壤类型分布图可公开获取。
佐布勒对FAO土壤单元评估的补充文档可从美国国家航空航天局（National Aeronautics and Space Administration, NASA）科学信息中心获取。
