Soil and Landscape Grid National Soil Attribute Maps - Drained Upper Limit Volumetric Water Content (Percent) (3 arc second resolution) Version 1

This is Version 1 of the Australian Drained Upper Limit Volumetric Water Content (DUL) product of the Soil and Landscape Grid of Australia.

The map gives a modelled estimate of the spatial distribution of Drained Upper Limit Volumetric Water Content soil hydraulic property in soils across Australia.

The Soil and Landscape Grid of Australia has produced a range of digital soil attribute products. Each product contains six digital soil attribute maps, and their upper and lower confidence limits, representing the soil attribute at six depths: 0-5 cm, 5-15 cm, 15-30 cm, 30-60 cm, 60-100 cm and 100-200 cm. These depths are consistent with the specifications of the GlobalSoilMap.net project. The digital soil attribute maps are in raster format at a resolution of 3 arc sec (~90 x 90 m pixels).

本数据集为澳大利亚土壤与景观网格（Soil and Landscape Grid of Australia）出品的澳大利亚田间持水量体积含水量（Drained Upper Limit Volumetric Water Content, DUL）产品第1版。

该数据集提供了澳大利亚全域土壤田间持水量体积含水量这一土壤水力特性的空间分布模型估算结果。

澳大利亚土壤与景观网格已推出一系列数字化土壤属性产品。每款产品均包含6张数字化土壤属性图及其上下置信限，分别对应6个土壤深度层级：0-5厘米、5-15厘米、15-30厘米、30-60厘米、60-100厘米及100-200厘米。该深度分层标准与GlobalSoilMap.net项目的规范保持一致。所有数字化土壤属性图均采用栅格格式，分辨率为3角秒（约90×90米像素）。
