A-train CALIOP and MLS observations of early winter Antarctic polar stratospheric clouds and nitric acid in 2008
A-train Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) and Microwave Limb Sounder (MLS) observations are used to investigate the development of polar stratospheric clouds (PSCs) and the gas-phase nitric acid distribution in the early 2008 Antarctic winter. Observational evidence of gravity-wave activity is provided by Atmospheric Infrared Sounder (AIRS) radiances and infrared spectro...

متن کاملSubtropical and Polar Cirrus Clouds Characterized by Ground-based Lidars and Calipso/caliop Observations
Cirrus clouds are product of weather processes, and then their occurrence and macrophysical/optical properties can vary significantly over different regions of the world. Lidars can provide height-resolved measurements with a relatively good both vertical and temporal resolutions, making them the most suitable instrumentation for high-cloud observations. The aim of this work is to show the pote...

متن کاملNitric Acid Trihydrate (NAT) formation at low NAT supersaturation in Polar Stratospheric Clouds (PSCs)
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) of small nitric acid (HNO3) containing particles (d<6μm) were observed at altitudes between 18 and 20 km. Provided the temperatures remain below the NAT equilibrium temperature TNAT, these NAT particles have the potent...
