%X Data assimilation has been successfully applied in atmospheric,oceanic,and land surface models.However,the four-dimensional variational(4DVar)assimilation system demands great computational costs.The authors introduced a new Historical-Sample-Projection data assimilation scheme(HSP-4DVar),and accomplished the HSP-4DVar land surface data assimilation system based on the Common Land Model(CoLM).As a scheme which requires no adjoint models,HSP-4DVar can be directly solved and easily realized,therefore avoids h...
