series are available from tide gauges in the Atlantic, Pacific, and Indian Oceans (e.g., Caldwell and Merrifield 2000 ). With the availability of these observations, model–data comparisons can be made using a variety of statistical metrics. In this paper, these data are applied in a detailed set of statistical metrics to evaluate NCOM performance in predicting SSH variability over the global ocean. In particular, daily averaged SSH from 612 yearlong daily time series from 282 tide gauges are used

airborne measurements using GPS dropwindsondes and stepped frequency microwave radiometers ( Powell et al. 1998 , 2003 ; Uhlhorn and Black 2003 ; Uhlhorn et al. 2007 ) as well as wind data gathered from temporary towers set up along the coast in the hurricane’s projected path ( Schroeder and Smith 2003 ). The area of least improvement has been in obtaining detailed data on the temporal/spatial evolution of the water level to evaluate the performance of the numerical models. Tide gauges in the

The symbols R and Z denote precipitation intensity and reflectivity, respectively, and the function G denotes transformation to the normal distribution. This paper is organized as follows. The proposed methodology is described in section 2 . Performance evaluation and demonstration of using S-DARTS in the CASA DFW domain is given in section 3 . Concluding remarks and

above model PPTR, based on static calibration at differing temperatures. 2. Static calibration Performance of the PPTR has been evaluated based on static calibration, in which the value of the input pressure was kept constant during a given measurement. The relationship between the input x and the output y of the PPTR was established as a first-order polynomial, of the well-known form y = mx ± c , and was determined by a least squares curve-fitting technique. The results of calibration were

the three schemes in YE15 . The paper is organized as follows. The estimation scheme, which is composed of the bottom Ekman boundary layer model and its adjoint model, and a minimization algorithm, is described in section 2 . In section 3 , a series of numerical experiments based on currents simulated with a prescribed EVP are performed to test the feasibility and effectiveness of the proposed scheme. The performance of the proposed scheme is compared with the three schemes in YE15 . Section

provide a detailed technical description of the destriping methodology. We also discuss the evaluation of image quality improvement and define two quantitative metrics to assess the performance of the stripe reduction algorithm. Section 3 provides information on the data used for this study and reports all the necessary results that demonstrate the benefits of destriping BTs on level 1B/SDR data prior to SST production. Section 4 concludes this paper. 2. Algorithm a. Noise model In the following

surface wind stress at the meso- γ scale (2–20 km) in the vicinity of an SST front and to evaluate the performance of the model using the selected parameterization. This selection and evaluation was done through comparison of MM5 simulations with in situ observations made during the Frontal Air–Sea Interaction Experiment (FASINEX) ( Friehe et al. 1991 ). Admittedly, the response of the MM5 boundary layer has been extensively tested over land ( Pleim and Xiu 1995 ; Davis et al. 1999 ; Bright and

). The next subsection evaluates the performance of this basic constraining model (5) . b. Performance of the basic constraining model The basic retrieval procedure (described in section 2a ) and computer code were verified using a simulated data set described in Protat et al. (1998) . A relative error of less than 1% was found for the dynamic perturbations. These errors are attributed to the discretization of the momentum and continuity equations involved in the retrieval procedure. In a
