you can also try www.myocean.eu.

it depends on the area and on the period in which you are interested, but this is a very complete data set (not only for winds)  

Try this product

http://globwave.ifremer.fr/

There you can find along-track wind speed from several altimeters in a single file (NetCDF).

Try the PODAAC data from Cross-Calibrated Multi-Platform (CCMP) project wind data

with Longitude/Latitude Resolution: 0.25 degrees x 0.25 degrees

Start/End Date: 1987-Jul-2 to 2011-Dec-31

since 6-hourly to monthly gridded analysis of ocean surface winds.

Is it possible to get wind DIRECTION from Altimeter?. I think only speed is possible.

From altimeter you can get U and V components of wind, them you can convert to wind direction by applying trigonometry.

Hello, you can also check this http://www.ncdc.noaa.gov/oa/rsad/air-sea/seawinds.html

Hi Aderito Aramuge do you have any coding for the wind direction calculation using the U and V component data from altimeter ?

Dear Jagadeesan,

You may check sentinel 3 data provided by ESA.

Best of luck!
