and 2004. In this section, a summary of the Noah LSM, a description of input data, and specifications for the assimilation experiments are presented. a. The Noah land surface model The Noah LSM is a one-dimensional (1D) soil–vegetation–atmosphere transfer (SVAT) model that is currently used for the operational Global Forecast System (GFS) and North American mesoscale (NAM) models by the National Centers for Environmental Protection (NCEP). Each 1D column of the Noah domain is composed of four soil

approaches to hydrometeorological problems include better estimation of initial soil moisture and temperature in mesoscale climatological models ( Jones et al. 2004 ; Huang et al. 2008 ), improved energy partitioning between latent and sensible heat fluxes ( Pipunic et al. 2008 ), and a concomitant higher skill in quantitative precipitation forecasts ( Koster et al. 2000 ). For example, it has been shown that updating soil moisture in a numerical weather model using passive microwave observations at

numerically. For any parameter ∏, the relative sensitivity σ of 〈ET〉 to ∏ can be approximated by where Δ〈ET〉 is the range in 〈ET〉, resulting from a small parameter perturbation Δ∏ (here 1%). h. ELDAS Soil parameters 1) TESSEL and HTESSEL Tiled ECMWF Scheme for Surface Exchanges over Land has been developed at the European Centre for Medium Range Weather Forecasts (ECMWF). In the original version of TESSEL, only one soil type exists. The physical properties of this soil ( Table 2 ) were chosen
