Arctic Rivers Dissolved Organic Carbon River Export Analysis

This repository has data for the estimation of dissolved organic carbon and colored dissolved organic carbon in the 6 Great Arctic Rivers. The data has been derived from the arcticgreatrivers.org repository for use in the USGS LOADEST model https://water.usgs.gov/software/loadest/ to predict river mass load as a function of measured discharge. The *_discharge.dat files contain the river discharge data from arcticgreatrivers.org and each *.tar directory with the river's name contain the output file from the LOADEST model with 100 model runs each for each parameter defined below. The netcdf file ArcticRivers_CarbonTrends.nc contains all of the LOADEST model prediction ensembles and mean/total seasonal values used in the trend analysis. DOC=Dissolved organic carbon (mg/L) CDOC=Colored dissolved organic carbon (mg/L) S1=CDOM absorption spectral slope between 275-295 nm (1/nm) S2=CDOM absorption spectral slope between 350-400 nm (1/nm) a300 = CDOM absorption at 300 nm (1/m) There is also a file River_CDOM_PUB.mat that is a MATLAB data structure with the data used to construct the LOADEST model input files. Dr. J. Blake Clark should be contacted at [e-mail] with any specific questions.本仓库包含用于估算6条北极大型河流中溶解有机碳与有色溶解有机碳的相关数据。 本数据集源自arcticgreatrivers.org仓库，供美国地质调查局（USGS）的LOADEST模型（https://water.usgs.gov/software/loadest/）使用，该模型可基于实测径流数据预测河流物质负荷。 `*_discharge.dat`文件包含从arcticgreatrivers.org获取的河川径流数据；每个以河流名称命名的*.tar目录中，均存放了LOADEST模型的输出文件，针对下述定义的每个参数均完成100次模型运行。 NetCDF格式文件`ArcticRivers_CarbonTrends.nc`包含了所有LOADEST模型预测集合，以及趋势分析中用到的季节均值与总量值。 参数定义如下： DOC：溶解有机碳（Dissolved organic carbon，mg/L） CDOC：有色溶解有机碳（Colored dissolved organic carbon，mg/L） S1：275~295 nm波段的有色溶解有机物（CDOM）吸收光谱斜率（1/nm） S2：350~400 nm波段的CDOM吸收光谱斜率（1/nm） a300：300 nm处的CDOM吸收系数（1/m） 另有`River_CDOM_PUB.mat`文件，该文件为MATLAB数据结构，存储了用于构建LOADEST模型输入文件的相关数据。 如有任何具体疑问，请联系J.
