Abstract：
Soil-Vegetation-Atmosphere Transfer (SVAT) models are a promising avenue towards gaining a better insight into land surface interactions and Earth\'s system dynamics. One such model developed for the academic and research community is the SimSphere SVAT model, a popular software toolkit employed for simulating interactions among the layers of vegetation, soil, and atmosphere on the land surface. The aim of the present review is two-fold: (1) to deliver a critical assessment of the model\'s usage by the scientific and wider community over the last 15 years, and (2) to provide information on current software developments implemented in the model. From the review conducted herein, it is clearly evident that from the models\' inception to current day, SimSphere has received notable interest worldwide, and the dissemination of the model has continuously grown over the years. SimSphere has been used so far in several applications to study land surface interactions. The validation of the model performed worldwide has shown that it is able to produce realistic estimates of land surface parameters that have been validated, whereas detailed sensitivity analysis experiments conducted with the model have further confirmed its structure and architectural coherence. Furthermore, the recent inclusion of novel functionalities in the model, as outlined in the present review, has clearly resulted in improving its capabilities and in opening up new opportunities for its use by the wider community. SimSphere developments are also ongoing in different aspects, and its use as a toolkit towards advancing our understanding of land surface interactions from both educational and research points of view is anticipated to grow in the coming years.
摘要：
土壤-植被-大气转移（SVAT）模型是一个有希望的途径，可以更好地了解地表相互作用和地球系统动力学。为学术和研究界开发的一个这样的模型是SimSphereSVAT模型，一种流行的软件工具，用于模拟植被层之间的相互作用，土壤,和陆地表面的大气。本审查的目的是双重的：（1）在过去15年中，对科学界和更广泛的社区使用该模型进行批判性评估，（2）提供有关模型中实现的当前软件开发的信息。从本文进行的审查来看，很明显，从模型开始到今天，SimSphere在全球范围内引起了人们的关注，多年来，该模型的传播不断增长。到目前为止，SimSphere已在多种应用中用于研究地表相互作用。在全球范围内对该模型进行的验证表明，它能够对经过验证的地表参数进行真实的估计，而使用该模型进行的详细敏感性分析实验进一步证实了其结构和建筑一致性。此外，最近在模型中包含了新的功能，如本审查所述，显然已经提高了其能力，并为更广泛的社区使用它开辟了新的机会。SimSphere的发展也在不同方面进行，它作为一个工具包，从教育和研究的角度推进我们对陆地表面相互作用的理解，预计在未来几年将会增长。
