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."}],"type":"journal_article"}
