AgMIP's global gridded crop model intercomparison (GGCMI) phase II CTWN-A archive: priority 1 outputs from EPIC-IIASA winter wheat simulations

This data set contains output data from simulations with the model EPIC-IIASA for winter wheat as part of AgMIP's Global Gridded Crop Model Intercomparison (GGCMI) phase II output data set. Output variables included are: crop yield, above-ground biomass, planting day, maturity day, potential irrigation water withdrawal, actual growing season evapotranspiration . Simulations are based on 31-year simulations using the AgMERRA (Ruane et al. 2015) data set with 4 atmospheric CO2 mixing ratios (C=360, 510, 660, 810 ppm) uniform offsets for temperature (T= -1, 0, 1, 2, 3, 4, 6 K), water (W= -50, -30, -20, -10, 0, 10, 20, 30 %, and infinite/irrigated), and 3 nitrogen input levels (N= 10, 60, 200 kgN/ha) using 2 assumptions on adaptation (A0= 'none', A1='regain original growing season').本数据集隶属于农业模型比对与改进计划（AgMIP）全球网格化作物模型比对计划（GGCMI）第二阶段产出数据集，包含使用EPIC-IIASA模型对冬小麦开展模拟得到的输出数据。所包含的输出变量为：作物产量、地上生物量、播种期、成熟期、潜在灌溉需水量、实际生长期蒸散量。本次模拟采用Ruante等（2015）发布的AgMERRA数据集开展31年时长的模拟试验，共设置多组扰动参数与适应假设：4种大气CO₂混合比（360、510、660、810 ppm）、7组温度均匀偏移量（T=-1、0、1、2、3、4、6 K）、8组水分扰动梯度（W=-50、-30、-20、-10、0、10、20、30 %，以及充分灌溉组）、3种氮肥投入水平（N=10、60、200 kgN/ha），并采用2种适应假设方案：A0=‘无适应’，A1=‘恢复原生长期’。
