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.本数据集仓库包含用于北极六大河流中溶解有机碳（Dissolved Organic Carbon, DOC）与有色溶解有机碳（Colored Dissolved Organic Carbon, CDOC）估算的相关数据。 本数据源自arcticgreatrivers.org数据集仓库，可用于美国地质调查局（United States Geological Survey, USGS）的LOADEST模型（https://water.usgs.gov/software/loadest/），该模型可基于实测径流量预测河流物质负载量。 *_discharge.dat 文件包含来自arcticgreatrivers.org的河流径流量数据；每个以河流名称命名的*.tar目录中，均存放LOADEST模型的输出文件，针对下述定义的每个参数各执行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各季节平均值与总量值。 各参数定义如下： DOC=溶解有机碳（mg/L） CDOC=有色溶解有机碳（mg/L） S1=275~295 nm波段间有色溶解有机物（Colored Dissolved Organic Matter, CDOM）吸收光谱斜率（单位：1/nm） S2=350~400 nm波段间CDOM吸收光谱斜率（单位：1/nm） a300=300 nm处的CDOM吸收系数（单位：1/m） 另有一份名为River_CDOM_PUB.mat的MATLAB数据结构文件，包含用于构建LOADEST模型输入文件的原始数据。 如有任何具体疑问，请联系J.
