Soil moisture data from the Oklahoma Mesonet have been used in numerous fields within the Earth sciences, including agriculture, hydrology, and meteorology. Soil matric potentials measured by heat dissipation sensors at Oklahoma Mesonet stations have been converted to soil volumetric water content estimates using soil water retention curve parameters estimated by the Rosetta pedotransfer function. Recently, an improved version of Rosetta, Rosetta3, was released. Informed by this new pedotransfer function and soil sampling at additional locations, an improved version of the Oklahoma Mesonet soil physical property database, MesoSoil v2.0, has been created. This article presents this new soil database, compares soil water retention parameters estimated using Rosetta3 with those derived from the original Rosetta model, and describes the effects of changes in those parameters on estimated volumetric water content. Using the Rosetta3 model led to changes in the estimated water retention parameters, most notably decreases in the parameter α, which is related to the inverse of the air-entry potential. These changes resulted in volumetric water content estimates that differed from those based on Rosetta1, with mean absolute differences averaging 0.02 cm3 cm–3 across all site-years and the greatest differences occurring during wet periods. The mean volumetric water content estimated using the Rosetta3 parameters across more than 100 sites was not significantly different from that determined by soil sampling. The updated database is publicly available and may be found here: http://soilphysics.okstate.edu/data.

MesoSoil v2.0:俄克拉荷马州 Mesonet 的更新土壤物理特性数据库

来自俄克拉荷马州 Mesonet 的土壤水分数据已用于地球科学的众多领域,包括农业、水文学和气象学。使用由 Rosetta pedotransfer 函数估计的土壤保水曲线参数,已将俄克拉荷马州 Mesonet 站散热传感器测量的土壤基质势转换为土壤体积含水量估计值。最近,发布了 Rosetta 的改进版本 Rosetta3。根据这个新的土壤转移函数和额外地点的土壤采样,俄克拉荷马州 Mesonet 土壤物理特性数据库的改进版本已经创建,MesoSoil v2.0。本文介绍了这个新的土壤数据库,将使用 Rosetta3 估计的土壤保水参数与从原始 Rosetta 模型得出的参数进行比较,并描述了这些参数的变化对估计体积含水量的影响。使用 Rosetta3 模型导致估计的保水参数发生变化,最显着的是参数 α 的减少,这与进气势的倒数有关。这些变化导致体积含水量估计值与基于 Rosetta1 的估计值不同,平均绝对差异平均为 0.02 厘米3 cm –3跨所有站点年份和最大的差异发生在潮湿时期。在 100 多个地点使用 Rosetta3 参数估计的平均体积含水量与通过土壤采样确定的没有显着差异。更新的数据库是公开可用的,可以在这里找到:http://soilphysics.okstate.edu/data。
