  abstract = {{W}e validated {J}ason-2 satellite altimeter {S}ensor {G}eophysical {D}ata {R}ecords ({SGDR}) by retracking 20-{H}z radar waveforms over the {C}alifornia coastal ocean using cycles 7-34, corresponding to {S}eptember 2008-{J}une 2009. {T}he performance of the ocean, ice, threshold, and modified threshold retrackers are examined using a reference geoid based on {E}arth {G}ravitational {M}odel 2008 ({EGM}08). {O}ver the shallow ocean (depth < 200 m), the modified threshold retracker, which is developed for noisy waveforms with preleading edge bump, outperforms the other retrackers. {I}t is also shown that retracking can improve the precision of sea surface heights ({SSH}s) for areas beyond 2-5 km from the shore. {A}lthough the ocean retracker generally performs well over the deep ocean (depth > 200 m), the ocean-retracked {SSH}s from some of the cycles are found to be less precise when the waveforms do not conform to the {B}rown ocean model. {W}e found that the retrackers developed for nonocean surfaces can improve the noisy ocean-retracked {SSH}s. {A}mong the retrackers tested here, the ice retracker overall provides the most precise {SSH} estimates over the deep ocean in average using cycles 7-34 in the study region.},
