The first direct laboratory measurements of gaseous hydrogen peroxide uptake by authentic Gobi and Saharan dust aerosol particles as a function of relative humidity (RH) have been carried out in an en...
Using aircraft measurements to determine the refractive index of Saharan dust during the DODO Experiments
aircraft measurements the refractive index Saharan dust the DODO Experiments
2010/8/12
Much uncertainty in the value of the imaginary part of the refractive index of mineral dust contributes to uncertainty in the radiative effect of mineral dust in the atmosphere. A synthesis of optical...
Uptake of NO3 and N2O5 to Saharan dust, ambient urban aerosol and soot: a relative rate study
NO3 and N2O5 Saharan dust ambient urban aerosol and soot a relative rate study
