The physical state of a material is described as its phase. Common phases of the molecule
H2O include vapor, liquid water, and ice. Examples of these phases in the atmosphere are …

Many of the significant advances in our understanding of atmospheric particles can be
attributed to the application of mass spectrometry. Mass spectrometry provides high …

Temperatures acquired by the Cryogenic Infrared Spectrometers and Telescopes for the
Atmosphere (CRISTA) during shuttle mission STS-66 have provided measurements of …

The homogeneous freezing of supercooled H 2 SO 4/H 2 O solution droplets was

A comprehensive investigation of polar stratospheric clouds was performed on 25 January
2000 with instruments onboard a balloon gondola flown from Kiruna, Sweden. Cloud layers …

This paper reviews experimental and theoretical work on the nonreactive uptake of acidic
trace gases such as HCl, HNO3, HBr, HONO, and SO2 on ice. The focus is on work …

Tunable vacuum ultraviolet (VUV) photoionization studies of water clusters are performed
using 10− 14 eV synchrotron radiation and analyzed by reflectron time-of-flight (TOF) mass …

A PSC was detected on 6 February 2003 in the Arctic stratosphere by in-situ measurements
onboard the high-altitude research aircraft Geophysica. Low number densities (~ 10-4 cm-3) …

The solid and liquid particles which constitute polar stratospheric clouds (PSCs) are of
manifold importance to the meteorology of the stratosphere. The heterogeneous reactions …
