  abstract = {{T}he {Y}asur volcano in the {V}anuatu archipelago is an outstanding source of infrasonic waves due to its regular activity. {T}his volcano is permanently monitored by the {IS}22 infrasound station located in {N}ew {C}aledonia, about 400 km from it, and by one microbarometer installed close to its crater. {A} multiyear monitoring of {Y}asur is proposed to validate consistently the {N}aval {R}esearch {L}aboratory {G}round to {S}pace ({NRL}-{G}2{S}) semiempirical atmospheric model up to the stratosphere. {T}he results of propagation modeling accurately explain seasonal changes as well as small short-timescale variations of the infrasonic observables. {T}he azimuthal deviation is predicted with an uncertainty in general lower than 0.5 degrees. {T}he fluctuations of the trace velocity and the celerity are simulated with errors as large as 5 m/s. {T}his study demonstrates that the use of appropriate propagation tools along with the {NRL}-{G}2{S} specifications provides accurate enough results for most of the long-range observations for the purpose of operational infrasound monitoring.},
