Representative work: The goal of this study is to produce a new soil moisture analysis for subseasonal forecasting. An accurate soil moisture initialization is today widely recognized as having a great potential to increase summertime subseasonal forecasting skill. In this study, soil moisture initial conditions are generated using the Precipitation Assimilation Reanalysis (PAR) technique. This technique consists mainly of nudging precipitation in a coupled land‐atmosphere model by adjusting the vertical air humidity profile based on the difference between model and observed precipitation rates in a continuous assimilation period of a few months. The effect of the PAR technique on the model soil moisture estimat We developed a coupled soil initialization scheme for the Florida State University/Center for Ocean-Atmosphere Prediction Studies (FSU/COAPS) climate model, which is coupled to the Community Land Model version 2. This method indirectly initializes the land surface component of the climate model by assimilating precipitation in the atmospheric component. A continuous assimilation is performed while the land and atmosphere components exchange fluxes, thus keeping the coupled model in a physically consistent state, obviating the need for any correction. Comparison with in situ observations in Illinois and Oklahoma shows very good agreement with the initialized soil moisture profile. A global co
