1. Introduction

This is repository for running model test for manuscript titled "The influence of hydrodynamics on lake ecosystem model simulations: a model experiment using three coupled hydrodynamic-biogeochemical models for four different lake types " registered with (gmd doi)

2. The source code

For those who would like to compile their own code, and for Linux and Mac users, you can follow the guide on (https://github.com/fabm-model/fabm/wiki) to compile your own models used in the simulations. We compiled the three hydrodyanmic model drivers with FABM code (https://github.com/fabm-model/fabm): FABM-0d driver(https://github.com/fabm-model/fabm/tree/master/src/drivers/0d), GOTM (https://github.com/gotm-model/code) and GOTM-lake(https://github.com/gotm-model/code/tree/lake). Within the FABM model option, point the PCLake-model to the code repository from https://github.com/fenjuan/pclaketestsrc.

3. Run the simulation

3.1 for windows users

1. click 1-run-gotm-lake.bat, and it will run gotm-lake model for the 4 simulations in gotm-lake directory.
2. click 1-run-gotm.bat, and it will run gotm model for the 4 simulations with gotm model in the gotm directory. This MUST run before fabm0d is run
3. click 2-extract-env0d.bat, and it will extract the temperature, shear stress from gotm models from the match depth, these will be used as input for fabm0d model.
4. click 3-run-fabm0d.bat, and it will run fabm0d for the 4 simulations in fabm0d directory.
5. click 4-gen-output.bat, then it will generate the figure 02-06 and table2 that presented in the manuscript. (The output netcdf files :nc, are in the folder output, together the python scripts that generate the figures and table, as well as the following output figures)

3.2 for linux and Mac users

1. follow step 1 to compile the code for three coupled hydrodyanmic-biogeochemical models described in the manuscript.
2. Following the order of gotm-lake, gotm, generate environment forcing for fabm0d, running fabm0d, finish the model run. You can see the *.bat files as reference. Finally use the python scripts in output directory to generate the figures and table.

4. Overview of the simulated hypothetic lakes

Lakes	depth(m)	Water voulm m-3	Residence time (day)	Layer number of 1D model
Lake 1	2m	2 * 2e06	100	5
Lake 2	5m	5 * 2e06	100	13
Lake 3	10m	10 * 2e06	100	25
Lake 4	20m	20 * 2e06	100	50

A release for May 2019 is available at
