We will perform local-scale measurements of net ecosystem exchange and soil status variables. Gridded 1D-model runs with AgroC, accounting for soil thermal, water and CO2 fluxes and plant growth, will provide the source/sink terms to the Large Eddy Simulation model developed by D6. The coupled AgroC/LES model will be used to investigate how and to which extent the within-field spatial pattern of CO2 release/uptake introduced by the subsurface and surface heterogeneities feeds back into the spatio-temporal variability of atmospheric CO2, water and heat fluxes.

我们将进行净生态系统交换和土壤状况变量的局部尺度测量。网格化的一维模型运行与AgroC，占土壤热，水和CO2通量和植物生长，将提供源/汇条款的大涡模拟模型开发的D 6。耦合AgroC/LES模式将被用来调查如何以及在何种程度上引入的地下和表面的异质性反馈到大气CO2，水和热通量的时空变异的CO2释放/吸收的田间空间格局。
