Preferred Label : residence time;
IUPAC definition : (atmospheric): the average time a molecule or aerosol spends in the atmosphere after
it is released or generated there. for compounds with well defined sources and emission
rates, this is estimated by the ratio of the average global concentration of a substance
to its production rate on a global scale. it is a function of not only the emission
rates but the loss rates by chemical and physical removal processes.; (instrumentation): the time required for air or reagent parcel to pass from the entrance
to the exit of an instrument. often this is approximated as the ratio of the interior
volume of the device to the flow rate.;
