  abstract = {{I}n {A}pril 2007, the {P}iton de la {F}ournaise volcano ({R}eunion island) entered into its biggest eruption recorded in the last century. {D}ue to the absence of a sensors network in the vicinity of the volcano, an estimation of degassing during the paroxysmal phase of the event has not been performed. {N}evertheless, the {SO}2 plume and aerosols have been observed by the {OMI} and {CALIOP} space sensors, respectively. {T}he mesoscale chemical model {M}eso{NH}-{C} simulates the observed bulk mass of {SO}2 and the general shape of the {SO}2 plume spreading over the {I}ndian {O}cean. {M}oreover, an analysis of the {SO}2 plume budget estimates a total {SO}2 release of 230 kt, among of which 60 kt have been transformed into {H}2{SO}4. 27 kt of {SO}2 and 21 kt of {H}2{SO}4 have been deposited at the surface by dry deposition. {W}ith this top down approach, the temporal evolution of the {SO}2 emission has been estimated during the most active period of the eruption. {T}he peak of degassing was estimated at 1800 kg s(-1) in the morning of 6 {A}pril. {T}he temporal evolution of {SO}2 emission presented here can also be used for local studies.},
