Abstract: In order to validate the sea surface reflectance model stressed by wind and calculate the accuracy of zero-wind calibration by sea surface return, the intensity and velocity characters of sea surface return were analyzed. For the intensity characters, we compared the sea surface reflectance model to the Doppler lidar observation data, with the consideration of the contribution from subsurface reflectance, and a good consistent was showed with the local sea surface windspeed in the result referring to the windspeed of QuikSCAT sea surface. For the velocity characters, we simulated the sea wave shape with considering the vertical and horizontal movement and calculated the sea surface velocity information.The zero-wind correction accuracy for Doppler lidar with the temporal integral measurement was less than 0.2 m/s.
