本文介绍了在法国气象局为将土壤水分和海洋盐度(SMOS)观测同化到陆地表面模式(LSM)相互作用土壤生物圈大气(ISBA)中而进行的一项研究。本研究由不同星载平台[先进对地微波扫描辐射计(AMSR-E)和欧洲遥感卫星散射计(ERS-SCAT)]提供的地表土壤水分信息与法国气象局的Systeme d‘analyse Fournissant des Renseignements Atteneriques a la neige(SAFRAN)、ISBA和耦合模式(MODCOU；SIM)2003-05年的再分析土壤湿度预报进行了相互比较试验。模型和遥感数据最初都与在法国西南部土壤水库实验地表监测(SMOSREX)的实验土壤水分监测点获得的现场观测结果进行了验证。两个不同的。
Abstract This paper presents a study undertaken in preparation of the work leading up to the assimilation of Soil Moisture and Ocean Salinity (SMOS) observations into the land surface model (LSM) Interaction Soil Biosphere Atmosphere (ISBA) at Meteo-France. This study consists of an intercomparison experiment of different space-borne platforms providing surface soil moisture information [Advanced Microwave Scanning Radiometer for Earth Observing (AMSR-E) and European Remote Sensing Satellite Scatterometer (ERS-Scat)] with the reanalysis soil moisture predictions over France from the model suite of Systeme d’analyse fournissant des renseignements atmospheriques a la neige (SAFRAN), ISBA, and coupled model (MODCOU; SIM) of Meteo-France for the years of 2003–05. Both modeled and remotely sensed data are initially validated against in situ observations obtained at the experimental soil moisture monitoring site Surface Monitoring of the Soil Reservoir Experiment (SMOSREX) in southwestern France. Two different ...
