  abstract = {{F}ollowing the anomalous warming event occurring in the tropical {N}orth {A}tlantic in 2010, higher than usual surface fugacity of {CO}2 (f{CO}(2)) was observed. {T}o evaluate the spatial extent of these anomalies and their drivers, and to quantify the sea-air {CO}2 flux at basin scale, the {M}ercator-{O}cean model is used from 2006 to 2014 within the region 0-30 degrees {N}, 70-15 degrees {W}. {M}odel outputs are generally in accordance with underway sea surface temperature, sea surface salinity, and surface f{CO}(2) recorded by two merchant ships. {T}he anomalous warming of 2010 is well reproduced by the model and is the main driver of f{CO}(2) anomalies. {T}he first coupled {E}mpirical {O}rthogonal {F}unction mode, between sea surface temperature and f{CO}(2), captures more than 70% of the total variance and is characterized by a basin-scale warming associated to positive f{CO}(2) anomalies. {T}he corresponding principal components are correlated to the {T}ropical {N}orth {A}tlantic {I}ndex and identify 2010 as the year with the highest positive anomaly over 2006-2014. {E}xceptions to this general pattern are located near the {A}frican coast, where the weakening of the coastal upwelling causes negative inorganic carbon anomalies, and close to the {A}mazon {R}iver plume, where f{CO}(2) anomalies are primarily associated with sea surface salinity anomalies. {A}lthough the f{CO}(2) anomalies of 2010 appear mostly in spring, they affect the annual {CO}2 budget and lead to an increased {CO}2 outgassing twice as large (46.2 {T}g {C} per year) as the mean annual flux over the 2006-2014 period (23.3 {T}g {C} per year).},
