Dr. Louise Bruce leads the GLM-MLCP which is a community driven initiative where numerous researchers from the GLEON and AEMON networks collectively simulate numerous lakes using a common approach to setup and assessment. More than 20 lakes have been simulated, ranging in latitude from 56oN to 38oS, in elevation from -210 to +560m above sea level, from trophic status of oligotrophic to eutrophic, depth from 12 to 253m, volume from 6.9e5 to 4.8e10 m3, mixing regimes from polymictic to meremictic and from a range of climates including warm lakes with lakes with seasonal ice cover. For each lake, standard sets of both forcing (input) data and calibration (field) data were collated.
