摘要
三江并流区地形、气候复杂多变,陆地水循环时空分异显著,水储量是刻画这一分异的重要水文要素之一。本数据集空间分辨率为1°,时间分辨率为月。该数据集是基于SRTM,参考GloRiC数据提取了三江并流区边界;利用2002-2016年的GRACE RL06 GSM月重力场模型反演获得了三江并流区的水储量,并使用双重尺度因子对反演的水储量进行了修正。基于STL等统计学方法计算了水储量的时空变化,最后使用线性拟合的方式量化了ENSO和水储量的关系。该数据集中包含:(1)研究区域边界数据(.shp);(2)区域水储量时空变化数据(.nc),包含反演的水储量和用于对比的模型结果;(3)水储量对ENSO的响应数据(.nc)。NetCDF数据分15层、使用不同维(1、2或3)存储。栅格数据空间分辨率为1°,时间分辨率为月。数据集由2组共9个文件组成,数据量1.69 MB(压缩为1个文件,559 KB)。
The Three Parallel Rivers Basin(TPRB)is characterized by rough terrain and variable climate.The significant water cycle heterogeneity in the TPRB can be captured by the change in terrestrial water storage(TWS).In this dataset,the boundary of the TPRB was extracted based on the SRTM(30 m),integrated with the GloRiC dataset,Google Earth images,and related research results.The TWS in the TPRB was retrieved using the GRACE RL06 GSM monthly gravity field model from 2002 to 2016,and the results were corrected using a double-scale factor.The relationship between ENSO and TWS was quantified by linear fitting.The dataset includes:(1)the boundary of the TPRB(.shp);(2)spatiotemporal variation data of TWS,including the retrieved water reserves and model results for comparison(.nc);and(3)response data of TWS to ENSO(.nc).The data in(2)and(3)are archived in fifteen layers and different dimensions(one,two,or three dimensions)in NetCDF with monthly data in 1°x 1°spatial resolution.The dataset is archived in two data files with data size of 1.69 MB.
