AgMIP's global gridded crop model intercomparison (GGCMI) phase II CTWN-A archive: priority 1 outputs from APSIM-UGOE soybean simulations

This data set contains output data from simulations with the model APSIM-UGOE for soybean 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, anthesis 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').

本数据集作为农业模型互比较计划（AgMIP）全球网格化作物模型互比较（GGCMI）第二阶段产出数据集的组成部分，包含基于APSIM-UGOE模型针对大豆开展的模拟试验输出数据。所涵盖的输出变量包括：作物产量、地上生物量、播种日期、成熟日期、开花日期、潜在灌溉需水量、实际生长季蒸散量。本次模拟采用AgMERRA（Ruane等，2015）数据集开展31年时长的模拟试验，设置了如下参数梯度与场景：4种大气CO₂体积混合比（C=360、510、660、810 ppm）、7组温度均匀偏移量（T=-1、0、1、2、3、4、6 K）、8组水分梯度（W=-50、-30、-20、-10、0、10、20、30%，以及无限灌溉/充分灌溉场景）、3种氮肥投入水平（N=10、60、200 kgN/ha），并针对适应措施设定2种假设场景（A0="无适应"，A1="恢复原生长季时长"）。
