  Lake ice within three Advanced Microwave Scanning Radiometer on EOS (AMSR-E)
pixels over the Great Bear and Great Slave Lakes have been simulated with the
Canadian Lake Ice Model (CLIMo). The resulting thicknesses and temperatures
were fed to a radiative transfer-based ice emissivity model and compared to the
satellite measurements at three frequencies---6.925 GHz, 10.65 GHz and 18.7
GHz. Excluding the melt season, the model was found to have strong predictive
power, returning a correlation of 0.926 and a residual of 0.78 Kelvin at 18
GHz, vertical polarization. Discrepencies at melt season are thought to be
caused by the presence of dirt in the snow cover which makes the microwave
signature more like soil rather than ice. Except at 18 GHz, all results showed
significant bias compared to measured values. Further work needs to be done to
determine the source of this bias.
