Excimer laser fragmentation-fluorescence spectroscopy as a method for monitoring ammonium nitrate and ammonium sulfate particles.
Excimer laser fragmentation-fluorescence spectroscopy (ELFFS) is shown to be an effective detection strategy for ammonium nitrate and ammonium sulfate particles at atmospheric pressure and room temperature. Following photofragmentation of the ammonium salt particle, fluorescence of the NH fragment is observed at 336 nm. The fluorescence signal is shown to depend linearly on particle surface are...

متن کاملParameterization of N2O5 reaction probabilities on the surface of particles containing ammonium, sulfate, and nitrate
A parameterization was developed for the heterogeneous reaction probability (γ ) of N2O5 as a function of temperature, relative humidity (RH), particle composition, and phase state, for use in advanced air quality models. The reaction probabilities on aqueous NH4HSO4, (NH4)2SO4, and NH4NO3 were modeled statistically using data and uncertainty values compiled from seven different laboratory stud...
متن کاملEffects of the physical state of tropospheric ammonium-sulfate-nitrate particles on global aerosol direct radiative forcing
The effect of aqueous versus crystalline sulfatenitrate-ammonium tropospheric particles on global aerosol direct radiative forcing is assessed. A global threedimensional chemical transport model predicts sulfate, nitrate, and ammonium aerosol mass. An aerosol thermodynamics model is called twice, once for the upper side (US) and once for lower side (LS) of the hysteresis loop of particle phase....
