abstract = {Satellite observations of polar stratospheric clouds (PSCs)
over Antarctica in June 2003 revealed small nitric acid
trihydrate (NAT) particles forming suddenly along the vortex
edge. Models suggest the trigger was mountain waves over the
Antarctic Peninsula (AP) forming ice for NAT nucleation. We
test this hypothesis by analyzing perturbations in
stratospheric radiances from the Atmospheric Infrared
Sounder (AIRS). AIRS data show mountain waves over the AP on
10-14 June, with no resolved wave activity before or after.
Peak wave temperature amplitudes derived from independent 40
hPa channels all return values of 10-12 K, in agreement with
values used to model this NAT event. These observations
support a NAT wake from a small region of mountain wave
activity over the AP as the source of this circumpolar NAT
outbreak. Citation: Eckermann, S. D., L. Hoffmann, M.
