  abstract = {{A}s part of the verification phase of the {TOPEX}/{POSEIDON} mission, 10-day gridded fields of altimeter data derived from {TOPEX} geophysical data records are compared with 10-day gridded fields of dynamic height derived from more than 60 moorings of the {T}ropical {O}cean and {G}lobal {A}tmosphere-{T}ropical {A}tmosphere {O}cean ({TOGA}-{TAO}) array in the {E}quatorial {P}acific ocean. {A}cess to {TAO} data in real time permits the first 500 days of the {TOPEX}/{POSEIDON} mission to be placed in the context of complementary, in situ measurements of surface winds, sea surface temperatures, and upper ocean thermal structure, as well as the time history of these variables prior to lauch. {A}nalysis of the space-time structure in the {TOPEX} and {TAO} surface topography data indicates sea level variability primarily due to equatorial {K}elvin wave activity generated by intense windbursts west of the date line in association with the 1991-1993 {E}l {N}ino. {C}ross correlations between the two data sets are generally >0.7, with {RMS} differences <4 cm. {H}owever, for reasons not fully understood, correlations drop to <0.5 in certain regions off the equator in the {E}astern {P}acific, and {RMS} differences can be >5 cm north of the equator in the {C}entral and {E}astern {P}acific.
