An Ocean Model’s Response to Scatterometer Winds
Two simulations of the North Atlantic have been run using the POP ocean model for approximately two and one half years each. One simulation used the 1.25◦ wind product from ECMWF and the other used the JPL Quikscat 0.25◦ gridded product. The resulting sea level anomaly fields from the simulations are quantified by using tide gauge and altimetric sea level anomaly data. In addition, upper ocean ...
متن کاملWave modelling for the north Indian Ocean using MSMR analysed winds
NCMRWF (National Centre for Medium Range Weather Forecast) winds assimilated with MSMR (Multi-channel Scanning Microwave Radiometer) winds are used as input to MIKE21 Offshore Spectral Wave model (OSW) which takes into account wind induced wave growth, non-linear wave-wave interaction, wave breaking, bottom friction and wave refraction. The model domain covers the north Indian Ocean, bounded by...

متن کاملMesoscale winds from the new ASCAT scatterometer
Introduction satellite based scatterometers provide high resolution all-weather wind vector fields over the seas. Wind speed and wind direction are provided at high accuracy under all weather conditions. The allweather EsA ERs scatterometer observations have proven its significant impact for the forecasting of fast developing and severe weather. Moreover, scatterometer wind fields are provided ...
متن کاملAccuracy of scatterometer-derived winds using the Cramer-Rao bound
A wind scatterometer makes measurements of the normalized radar-backscatter coefficient of the ocean surface. To retrieve the wind, a geophysical model function (GMF), which relates to the near-surface wind, is used. The wind vector can be estimated using maximum-likelihood techniques from several measurements made at different azimuth angles. The probability density of the measured is assumed ...
