text: "Field measurements of aboveground net primary productivity (ANPP) in\r\ntemperate
grasslands suggest that both positive and negative asymmetric\r\nresponses to
changes in precipitation (P) may occur. Under normal range of\r\nprecipitation
variability, wet years typically result in ANPP gains being\r\nlarger than ANPP
declines in dry years (positive asymmetry), whereas\r\nincreases in ANPP are lower
in magnitude in extreme wet years compared to\r\nreductions during extreme drought
(negative asymmetry). Whether the current\r\ngeneration of ecosystem models with
a coupled carbon–water system in\r\ngrasslands are capable of simulating these
asymmetric ANPP responses is an\r\nunresolved question. In this study, we evaluated
the simulated responses of\r\ntemperate grassland primary productivity to scenarios
of altered\r\nprecipitation with 14 ecosystem models at three sites: Shortgrass\r\nsteppe
(SGS), Konza Prairie (KNZ) and Stubai Valley meadow (STU), spanning a\r\nrainfall
gradient from dry to moist. We found that (1) the spatial slopes\r\nderived from
modeled primary productivity and precipitation across sites were\r\nsteeper than
the temporal slopes obtained from inter-annual variations, which\r\nwas consistent
with empirical data; (2) the asymmetry of the responses of\r\nmodeled primary
productivity under normal inter-annual precipitation\r\nvariability differed among
models, and the mean of the model ensemble\r\nsuggested a negative asymmetry across
the three sites, which was contrary to\r\nempirical evidence based on filed observations;
(3) the mean sensitivity of\r\nmodeled productivity to rainfall suggested greater
negative response with\r\nreduced precipitation than positive response to an increased
precipitation\r\nunder extreme conditions at the three sites; and (4) gross primary
productivity\r\n(GPP), net primary productivity (NPP), aboveground NPP (ANPP)
and belowground\r\nNPP (BNPP) all showed concave-down nonlinear responses to altered\r\nprecipitation
in all the models, but with different curvatures and mean\r\nvalues. Our results
indicated that most models overestimate the negative\r\ndrought effects and/or
underestimate the positive effects of increased\r\nprecipitation on primary productivity
under normal climate conditions,\r\nhighlighting the need for improving eco-hydrological
processes in those\r\nmodels in the future."
