New Synthetic Aperture Radar (SAR) vegetation index: correlation test with optical vegetation indices and rainfall data used in the approach

The dataset is important to an article being evaluated by the International Journal of Remote Sensing, which main to propose a new SAR (Synthetic Aperture Radar) vegetation index and performs an evaluation of this index about seasonal and spatial influences. So the dataset brings the results of the Spearman Correlation's test from indices assessment. Also as part of indices assessment about seasonal influences, rainfall data were important in the approach, thus the dataset contains also rainfall data measured from adopted rain gauges.该数据集与一篇正在《国际遥感学报》（International Journal of Remote Sensing）评审的论文高度相关，该论文核心目标为提出一种新型合成孔径雷达（Synthetic Aperture Radar，SAR）植被指数，并围绕该指数的季节与空间影响展开系统性评估。本数据集收录了该指数评估过程中所得的斯皮尔曼相关性检验结果。此外，鉴于在针对季节影响的指数评估环节中，降雨数据为研究方法的关键组成部分，因此本数据集同时包含了通过所采用雨量计实测得到的降雨数据。
