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...
NAT-rock formation by mother clouds: a microphysical model study
NAT-rock formation mother clouds microphysical model
2009/3/12
Polar stratospheric clouds (PSCs) of type 1a or 1a-enh containing high number densities of nitric acid trihydrate (NAT) particles, can act as mother clouds for extremely large NAT particles, termed NA...
Commentary on“Homogeneous nucleation of NAD and NAT in liquid stratospheric aerosols: insufficient to explain denitrification”by Knopf et al.
Homogeneous nucleation NAD NAT liquid stratospheric aerosols
2009/3/11
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
large NAT particles polar stratosphere cosmic rays solar activity
2009/3/10
The formation of large nitric acid trihydrate (NAT) particles has important implications for denitrification and ozone depletion. Existing theories have difficulty in explaining the formation of large...
Influence of mountain waves and NAT nucleation mechanisms on polar stratospheric cloud formation at local and synoptic scales during the 1999-2000 Arctic winter
mountain waves NAT nucleation mechanisms polar stratospheric cloud formation Arctic winter
2009/2/7
A scheme for introducing mountain wave-induced temperature pertubations in a microphysical PSC model has been developed. A data set of temperature fluctuations attributable to mountain waves as comput...
Spectroscopic evidence for NAT, STS, and ice in MIPAS infrared limb emission measurements of polar stratospheric clouds
Spectroscopic evidence NAT STS MIPAS limb emission polar stratospheric clouds
