- •
We model the gas component of the Enceladus plume using detailed gas dynamics.
- •
We constrain the model using several INMS and UVIS data sets.
- •
We estimate H2O production rates of a few hundred kgs−1 from the plume.
- •
Narrow emissions produce better fits to data, suggesting a subsurface origin.
- •
The distributed Tiger Stripe sources are likely dominant while the jets provide a lesser contribution.
