Code for lake energy and water balance model, Toolik Lake, Alaska, 2018

This dataset includes source code for a lake energy and water balance model that originates from the 1-dimensional lake energy balance model of Hostetler and Bartlein (1990). This lake model has been used to simulate seasonal and subseasonal conditions in lakes north of the Brooks Range in Alaska, testing the paleoclimate interpretations of temperature proxies derived from lake sediment cores in support of NSF Award 1504069. The model simulates lake physical processes including energy exchange with the atmosphere and with sediments, convective and diffusive mixing, ice formation and melt, and water balance. The model requires meteorological inputs including air temperature, humidity, wind speed, surface shortwave radiation, surface longwave radiation, surface pressure, precipitation, and basin runoff. A number of lake-specific parameters (e.g., depth, salinity, surface albedo) allow this model to simulate lakes in diverse climates and physical settings. The source code is written in Fortran 90 and may be compiled with open-source compilers such as gfortran.
