  abstract = {{B}romo is among the very active volcanoes in {I}ndonesia and is known for its recurrent and long-lasting eruptive manifestations. {P}ast volcanic gas studies have revealed {B}romo as one of the principal sources of volcanic degassing in {I}ndonesia. {T}his high degassing from {B}romo volcano is further characterized in this work, based on more than 10 years of intermittent ground-based gas measurements, combined with daily {SO}2 mass, captured by the {OMI} sensor. {O}ver the past decade, {B}romo has released 0.7 {T}g of {SO}2 into the atmosphere, representing 3% of the volcanic degassing budget of {I}ndonesia and 0.3% of the global volcanic {SO}2 emission budget outside eruptive periods. {R}esults also reveal that 18.8 {T}g of {H}2{O}, 2.0 {T}g of {CO}2, 0.1 {T}g of {H}2{S}, and 0.005 {T}g of {H}-2 were released from the {B}romo volcano in one decade. {A}bout 81% of these gases are released passively between eruptive events. {T}he chemistry of the eruptive products, sampled between 2001 and 2019, indicate that {B}romo volcanic activity is sustained by a basaltic-andesite to basalt trachy-andesite magma source with a transition from medium-{K} to high-{K} composition. {S}uch an evolution associated to a {C}-rich gas likely resulted from a low partial melting and sediment contribution to the genesis of the source magma. {N}ew magma injections into the reservoir and fractional crystallization have further amplified the changes of magma composition. {F}inally, we speculate that the shallow reservoir replenishment, in response to the continuous strong degassing is the driving mechanism behind the {B}romo frequent eruptive events.},
