-This directory contains the two AED configuration files ("aed2_20210204_2DOCpools.nml" for the reservoir's biogeochemistry, "aed2_phyto_pars_30June2020.nml" for the reservoir's phytoplankton community) with calibrated parameters for FCR. 
+This directory contains the two AED configuration files ("aed2_20210204_2DOCpools.nml" for the reservoir's biogeochemistry, "aed2_phyto_pars_30June2020.nml" for the reservoir's phytoplankton community) with calibrated parameters for FCR. These files are used to simulate observed dynamics in the reservoir from 2013-2019. The additional files (all with prefixes of "half" or "2x") refer to the files used in the parameter sensitivity analysis of halving/doubling sensitive parameters.
 
 ## output
 After the model is run, this directory contains the output netcdf files from GLM-AED. This directory also contains summarized output in CSV files needed for the analysis in Carey et al. (including t-test statistics, % reservoir retention, modeled vs. observed elemental concentrations and ratios, etc.)
