Near-real time ocean surface currents derived from satellite altimeter JASON-1, GFO, ENVISAT and scatterometer QSCAT data on 1 degree 1 degree resolution for world oceans 60 degrees S to 60 degrees N are available online as Ocean Surface Current Analyses Real Time OSCAR . The probability distribution function PDF of the current speeds w, constructed from global OSCAR data from 1992 to 2008, satisfies the two-parameter Weibull distribution reasonably well, and such a PDF has little seasonal and interannual variations. Knowledge on PDF of w will improve the ensemble horizontal flux calculation, which contributes to the climate studies.
