Homogeneous nucleation of NAD and NAT in liquid stratospheric aerosols: insufficient to explain denitrification
Homogeneous nucleation NAD NAT liquid stratospheric aerosols
2009/3/12
The nucleation of NAD and NAT from HNO3/H2O and HNO3/H2SO4/H2O solution droplets is investigated both theoretically and experimentally with respect to the formation of polar stratospheric clouds (PSCs...

In a recent published paper Knopf et a1. (2002) have suggested that the homogeneous freezing behavior of stratospheric aerosols, under polar winter conditions, can be simulated experimentally in large...
Formation of large NAT particles and denitrification in polar stratosphere: possible role of cosmic rays and effect of solar activity
