Abstract in another language

The biological responses to precipitation within the terrestrial components of Earth systemmodels, or land surface models (LSMs), are mechanistically simple and poorly constrained, leavingprojections of terrestrial ecosystem functioning and feedbacks to climate change uncertain. A number offield experiments have been conducted or are underway to test how changing precipitation will affectterrestrial ecosystems. Results from these experiments have the potential to vastly improve modeledprocesses. However, the transformation of experimental results into model improvements still represents agrand challenge. Here we review the current state of precipitation manipulation experiments and theprecipitation responses of biological processes in LSMs to explore how these experiments can help improvemodel realism. First, we discuss contemporary precipitation projections and then review the structure andfunction of current-generation LSMs. We then examine different experimental designs and discuss basicvariables that, if measured, would increase a field experiment’s usefulness in a modeling context. Next, wecompare biological processes commonly measured in the field with their model analogs and find that, inmany cases, the way these processes are measured in the field is not compatible with the way they arerepresented in LSMs, an effect that hinders model development. We then discuss the challenge of scalingfrom the plot to the globe. Finally, we provide a series of recommendations aimed to improve the connectivitybetween experiments and LSMs and conclude that studies designed from the perspective of researchers in bothcommunities will provide the greatest benefit to the broader global change community.
