Parameter values used to run the weather generator under different climatic scenarios.

Current climate indicate parameters used to run the model under current climate based on instrumental records (weather station at Senda Darwin Biological Station, period 1998–2009). Radiation describes parameters daily global radiation Rgµ and Rgσ (the latter in brackets, µmol(photons) m−2 s−1). Temperature is mean daily air temperature. Future scenarios are the range of climatic parameters that were varied to run the model under increased drought (36 scenarios in total, see Methods for details). DJF: December to February (austral summer, growing season); MAM: March to May (austral autumn); JJA: June to August (austral winter), SON: September to November (spring, growing season). sd: standard deviation.当前气候参数：指基于仪器观测记录（森达·达尔文生物站气象站，1998—2009年时段），用于当前气候条件下模型运行的参数。辐射项涵盖每日全球辐射Rgµ与Rgσ（括号内标注后者的单位：微摩尔(光子)·米⁻²·秒⁻¹）。气温项为每日平均气温。未来情景指为模拟干旱加剧条件下的模型运行而设置的可变气候参数组合，共计36种情景，详细说明参见研究方法部分。DJF：12月至次年2月（南半球夏季，作物生长季）；MAM：3月至5月（南半球秋季）；JJA：6月至8月（南半球冬季）；SON：9月至11月（南半球春季，作物生长季）。sd：标准差（standard deviation）。
