  abstract = {{T}he 8th {I}nternational {C}omparison of {A}bsolute {G}ravimeters ({ICAG}2009) took place at the headquarters of the {I}nternational {B}ureau of {W}eights and {M}easures ({BIPM}) from {S}eptember to {O}ctober 2009. {I}t was the first {ICAG} organized as a key comparison in the framework of the {CIPM} {M}utual {R}ecognition {A}rrangement of the {I}nternational {C}ommittee for {W}eights and {M}easures ({CIPM} {MRA}) ({CIPM} 1999). {ICAG}2009 was composed of a {K}ey {C}omparison ({KC}) as defined by the {CIPM} {MRA}, organized by the {C}onsultative {C}ommittee for {M}ass and {R}elated {Q}uantities ({CCM}) and designated as {CCM}.{G}-{K}1. {P}articipating gravimeters and their operators came from national metrology institutes ({NMI}s) or their designated institutes ({DI}s) as defined by the {CIPM} {MRA}. {A} {P}ilot {S}tudy ({PS}) was run in parallel in order to include gravimeters and their operators from other institutes which, while not signatories of the {CIPM} {MRA}, nevertheless play important roles in international gravimetry measurements. {T}he aim of the {CIPM} {MRA} is to have international acceptance of the measurement capabilities of the participating institutes in various fields of metrology. {T}he results of {CCM}.{G}-{K}1 thus constitute an accurate and consistent gravity reference traceable to the {SI} ({I}nternational {S}ystem of {U}nits), which can be used as the global basis for geodetic, geophysical and metrological observations of gravity. {T}he measurements performed afterwards by the {KC} participants can be referred to the international metrological reference, i.e. they are {SI}-traceable. {T}he {ICAG}2009 was complemented by a number of associated measurements: the {R}elative {G}ravity {C}ampaign ({RGC}2009), high-precision levelling and an accurate gravity survey in support of the {BIPM} watt balance project. {T}he major measurements took place at the {BIPM} between {J}uly and {O}ctober 2009. {A}ltogether 24 institutes with 22 absolute gravimeters(32) and nine relative gravimeters participated in the {ICAG}/{RGC} campaign. {T}his paper is focused on the absolute gravity campaign. {W}e review the history of the {ICAG}s and present the organization, data processing and the final results of the {ICAG}2009. {A}fter almost thirty years of hosting eight successive {ICAG}s, the {CIPM} decided to transfer the responsibility for piloting the future {ICAG}s to {NMI}s, although maintaining a supervisory role through its {C}onsultative {C}ommittee for {M}ass and {R}elated {Q}uantities.},
