SoilGrids250m 2017-03 - Derived available soil water capacity (volumetric fraction) with FC = pF 2.3

Derived available soil water capacity (volumetric fraction) with FC = pF 2.3 at 7 standard depths predicted using the global compilation of soil ground observations. Accuracy assessement of the maps is availble in Hengl et at. (2017) DOI: 10.1371/journal.pone.0169748. Data provided as GeoTIFFs with internal compression (co='COMPRESS=DEFLATE'). Measurement units: v%.

本数据集为基于全球土壤地面观测汇编数据预测得到的7个标准深度下的土壤有效持水量（体积分数），其田间持水量（Field Capacity，FC）对应pF值2.3。该数据栅格的精度评估详见Hengl等人2017年的研究文献（DOI: 10.1371/journal.pone.0169748）。数据以GeoTIFF格式提供，内部采用DEFLATE压缩（编码参数为co='COMPRESS=DEFLATE'）。测量单位：体积百分比（v%）。
