Work Description

The files in this archive include ASCII input files (Mondrian-Seed-v43.txt, Mondrian-Para-v43.txt, Mondrian-Scenario-v43.txt, Mondrian-Batch-v43.txt) for an ecosystem simulation model Mondrian, .xlsx setup files that describe these inputs, including descriptions of column and row heading otherwise missing from the .txt files, and how to enter them properly (Mondrian-SeedFileSetup-v43.xlsx, Mondrian-ParaFileSetup-v43.xlsx, etc), and .txt model output files (MondrianResultsBGC_restime21_1.txt, MondrianResultsBGC_restime21_2.txt, etc.). The .xlsx setup files associated with each .txt input file describes what each column represents and how they are input into the model. The first 132 rows of the �MondrianResultsBGC�� output .txt files include metadata and descriptions of each data column below. Each output file corresponds to a certain combination of input files. The �workflow� tab in the included spreadsheet �restime_2.1.xlsx� describes each of these output files and what specific combinations they include. �restime_2.1.xlsx� also includes the objective and brief description of this project (�overview� tab) and details about the independent variables and how they were manipulated for this model experiment (tab �Model setup). Additionally, there is a comprehensive Mondrian User Guide word doc (.docx) that describes in more detail each of the files listed above, how they are used, and how the Mondrian model works for further reference. Finally, these is a .xlsx spreadsheet named �sentinel_site_calibration� which shows data from 5 selected sentinel sites that were used to calibrate a newly added denitrification process function in Mondrian. The tab titled �matrix� contains information used for calibration of two model scaling parameters (denitrif parm and nitrif parm) including field observations (heading = �Observed values from field studies�), best fitting scaling parameter value, (heading = �Chosen scaling parameter values�), model predictions (heading = �Model calibration output�), best estimates of field data for model input (heading = �Mondrian calibration input�). The text box on the �matrix� tab represents the final calibration values used for the model. The �denitrification calibration� tab includes output of iterative calibration simulations sets (Exercises 1-9) with brief description of what is different about this set of simulations in which �denitrif parm�, �nitrif parm� and other values were �tweaked� to achieve a least sum of squares value, which was them deemed �best fit� for these calibration parameters. The following tabs (�Old Woman Creek�, St Louis Bay�, etc) represent field data compiled from each study used for calibration, including best estimates of nitrogen loading rates, hydrologic flushing rates, water level and hydroperiod, plant communities, and regional climate data. The �conversions� tab includes brief conversion calculations used to standardize all data for comparison and model input.
