  abstract = {{I}n this paper, we present {T}rop{F}lux wind stresses and evaluate them against observations along with other widely used daily air-sea momentum flux products ({NCEP}, {NCEP}2, {ERA}-{I} and {Q}uik{SCAT}). {T}rop{F}lux wind stresses are computed from the {COARE} v3.0 algorithm, using bias and amplitude corrected {ERA}-{I} input data and an additional climatological gustiness correction. {T}he wind stress products are evaluated against dependent data from the {TAO}/{TRITON}, {PIRATA} and {RAMA} arrays and independent data from the {O}cean{SITES} mooring networks. {W}ind stress products are more consistent amongst each other than surface heat fluxes, suggesting that 10 m-winds are better constrained than near-surface thermodynamical parameters (2 m-humidity and temperature) and surface downward radiative fluxes. {Q}uik{SCAT} overestimates wind stresses away from the equator, while {NCEP} and {NCEP}2 underestimate wind stresses, especially in the equatorial {P}acific. {Q}uik{SCAT} wind stress quality is strongly affected by rain under the {I}nter {T}ropical {C}onvergence {Z}ones. {ERA}-{I} and {T}rop{F}lux display the best agreement with in situ data, with correlations > 0.93 and rms-differences < 0.012 {N}m(-2). {T}rop{F}lux wind stresses exhibit a small, but consistent improvement (at all timescales and most locations) over {ERA}-{I}, with an overall 17 % reduction in root mean square error. {ERA}-{I} and {T}rop{F}lux agree best with long-term mean zonal wind stress observations at equatorial latitudes. {A}ll products tend to underestimate the zonal wind stress seasonal cycle by similar to 20 % in the western and central equatorial {P}acific. {T}rop{F}lux and {ERA}-{I} equatorial zonal wind stresses have clearly the best phase agreement with mooring data at intraseasonal and interannual timescales (correlation of similar to 0.9 versus similar to 0.8 at best for any other product), with {T}rop{F}lux correcting the similar to 13 % underestimation of {ERA}-{I} variance at both timescales. {F}or example, {T}rop{F}lux was the best at reproducing westerly wind bursts that played a key role in the 1997-1998 {E}l {N}io onset. {H}ence, we recommend the use of {T}rop{F}lux for studies of equatorial ocean dynamics.},
