Input and Output Variables for the biogeochemical modeling study of the Lakes Response to Climate Change, Internal Loads and Restoration Measures

The main goal of this work is to quantify seasonal effluxes of soluble phosphorus from sediments in lakes and reservoirs by means of mechanistic biogeochemical modelling. The MyLake-Sediment model, available freely on GitHub (https://github.com/biogeochemistry/MyLake_v2_Vansjo), was used to reproduce daily water quality variables and predict sediment-water column exchange fluxes over the boreal Lake Vansjø, Norway. MyLake-Sediment was first used to simulate the impacts of increasing air temperature on algal growth. In another scenario, phosphorus loading from the watershed to the lake was halted in order to quantify the response to internal P loading. Finally, we simulated the decreasing dissolved phosphate efflux from the sediment when reactive iron was added to the water column. The data provided here contains the input variables used in the modelling study as well as the model output variables.
