The General Lake Model Multi-Lake Comparison Project (GLM-MLCP) is a community driven initiative where researchers from the Global Lake Ecological Observatory Network (GLEON) and Aquatic Ecosystem Modeling Network (AEMON) collectively simulate lakes using a common approach to setup and assessment. More than 20 lakes, including Oneida Lake, have been simulated, ranging in latitude from 56°N to 38°S, in elevation from -210 to +560 m above sea level, in trophic status from oligotrophic to eutrophic, in depth from 12 to 253 m, in volume from 6.9x105 to 4.8x1010 m3, in mixing regimes from polymictic to meromictic and in climates, including warm lakes to lakes with seasonal ice cover. The expected outcome of the study is an improved knowledge of the strength and limitations of the GLM, a standardized calibration and globally relevant parameter set, and an improved understanding of characteristic drivers and forcing patterns of stratification in lakes. The analysis highlights the ability of the model to capture varying stratification based on lake morphometry and prevailing climate. A globally validated model allows better assessment of global change impacts on lake and reservoirs.
