The scatterometer onboard HY-2 satellite is calibrated using Numerical Ocean Calibration and its retrieval winds after calibration are validated from 130 global buoys and winds from the European Centre for Medium-Range Weather Foresting Numerical Weather Prediction model using triple-collocation during December 2012

resulting in 3112 collocated triplets.The KNMI QC flag is used to collocate the data without rain efforts.It is found that functional relationship employing the error-in-variables method is more accuracy than that using linear regression for the validation of retrieval wind from HY-2 scatterometer.Moreover

using the wind component domain is confirmed to be favourable.It is shown that the uncertainties after ocean calibration is less than 0.15dB

resulting in 0.2m/s systematic wind effects.For both zonal and meridional winds

the similar wind fields comparing with buoys and ECMWF indicate that the effective of the calibration and high quality of the retrieval winds.
