While benchmarking within the land surface community is transitioning to more quantitative evaluation techniques, there is little discussion of the level of performance we should expect from a model. Expectations are clearly dependent on the nature of a particular experimental setup and the relative complexity of the model being used. This talk will show how empirical models offer one approach to defining performance expectations a priori and argue that understanding expectations should be a crucial part of any benchmarking exercise. An automated implementation of empirical model based benchmarking will be shown from the Protocol for the Analysis of Land Surface Models (PALS), a free online land surface model benchmarking tool.
