MEANDIR Inversion Results for Hydrologic and Landscape Controls on Rock Weathering Along a Glacial Gradient in South Central Alaska, USA

These datafiles contain inverse geochemical mixing model results from Hydrologic and Landscape Controls on Rock Weathering Along a Glacial Gradient in South Central Alaska, USA https://doi.org/10.1029/2023JF007255. The files consist of a summary file FXiso.csv and FXmajor.csv which have the sample id, date sampled, and umol concentrations of major elements as well as the median fractional contribution and 25th and 75th percentile from each endmember for 179 samples in the isotopic and major inversion, respectively. The matlab files iso_all.mat and Majors_all.mat consist of n 5x200x179 matrices where each of the n matrices contain results for the fractional contribution of each of the 5 endmembers [1:precipitation, 2:pyrite, 3:carbonate, 4:silicate, 5:clay] to the n elements utilized in the inversion. The 200 inversion results are in the same order and follow the same index as the 179 samples in the summary files. For example, once loaded in matlab the command: data.Na(1,:,2) would show precipitation(index 1) endmember 200 inversion results(index : ) for the second sample 'kbgws-070319' (index 2). If brought into python note that the indexing starts at 0 not 1.本数据集包含来自美国阿拉斯加中南部沿冰川梯度的岩石风化水文与景观控制因素研究的反地球化学混合模型（inverse geochemical mixing model）结果，相关研究论文DOI为：10.1029/2023JF007255。数据集包含两个汇总文件FXiso.csv与FXmajor.csv，其中FXiso.csv对应同位素反演结果，FXmajor.csv对应主量元素反演结果，二者均收录了179个样本的样本ID、采样日期、主量元素微摩尔浓度，以及各端元（endmember）贡献分数的中位数、25%分位数与75%分位数。MATLAB格式文件iso_all.mat与Majors_all.mat包含n组5×200×179的矩阵，每组矩阵对应5个端元（1：降水端元，2：黄铁矿端元，3：碳酸盐端元，4：硅酸盐端元，5：黏土端元）对反演中使用的n种元素的贡献分数。200次反演结果的顺序与汇总文件中的179个样本一一对应。示例：在MATLAB中执行命令data.Na(1,:,2)，即可查看第二个样本'kbgws-070319'（索引为2）中钠元素的降水端元对应的全部200次反演结果。若在Python中导入该数据集，需注意其索引起始值为0而非1。
