  abstract = {{G}ravity field and steady state {O}cean {C}irculation {E}xplorer ({GOCE}) gravity gradient data of the entire science mission and data from {LAGEOS} 1/2 and {G}ravity {R}ecovery and {C}limate {E}xperiment ({GRACE}) were combined in the construction of a satellite-only gravity field model to maximum degree 300. {W}hen compared to {E}arth {G}ravitational {M}odel 2008, it is more accurate at low to medium resolution, thanks to {GOCE} and {GRACE} data. {W}hen compared to earlier releases of {E}uropean {S}pace {A}gency {GOCE} models, it is more accurate at high degrees owing to the larger amount of data ingested, which was moreover taken at lower altitude. {T}he impact of orbiting at lower altitude in the last year of the mission is large: a model based on data of the last 14 months is significantly more accurate than the release 4 model constructed with the first 28 months. {T}he (calibrated) cumulated geoid error estimate at 100 km resolution is 1.7 cm. {T}he optimal resolution of the {GOCE} model for oceanographic application is between 100 and 125 km.},
