AB: As a result of the increased availability of eddy-covariance flux data globally, the area of Land Surface Model (LSM) evaluation has an opportunity to move beyond calibrate-and-compare-with-observation perspective that usually constitutes evaluation. This presentation will briefly outline several innovative model evaluation techniques that demonstrate the increased depth of understanding projects such as Fluxnet can provide to the LSM community. Issues addressed include: efficiency of utilisation of information available to LSMs in predicting fluxes; the meaning of calibration in the context of systematic model bias, and; the appropriateness of vegetation type divisions.
