  - "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.@eng"
