comprehensive view of Arctic cloudiness in all seasons ( Intrieri et al. 2002 ) and a particularly wealthy set of mixed-phase cloud observations. Shupe et al. (2005) outlined an operational cloud property retrieval suite that combines cloud radar, lidar, dual-channel microwave radiometer, and radiosonde data to classify cloud types and retrieve cloud microphysical properties for the clouds observed at SHEBA. That study specifically focused on single-phase cloud retrievals and provided statistical results

polarization of downwelling thermal microwave radiation at a wavelength λ = 2.25 cm in the presence of liquid precipitation. Detailed studies conducted by Kutuza et al. (1998) and Zagorin and Kutuza (1998) suggested that the observed polarization is caused by the nonsphericity and preferential orientation of raindrops. Experimental observations of the upwelling microwave radiation from precipitating clouds have also been collected from spaceborne platforms (e.g., Spencer et al. 1989 ; Heymsfield

variance scaling from the Atmospheric Infrared Sounder (AIRS) Advanced Microwave Sounding Unit (AMSU) (hereafter simply AIRS) suite between ~150 and 1300 km. A rich variety of structure in the scaling exponents was revealed from these observations that were not previously reported from aircraft (e.g., Nastrom and Gage 1985 ) and satellite observational studies (e.g., Cahalan et al. 1994 ) owing to aircraft sampling limitations and ambiguities in interpreting raw satellite radiances ( KT09

by where y is the measurement vector, or set of remote sensing observations (microwave brightness temperatures and vertical profiles of radar reflectivity), each with an associated measurement error, and x is the state vector, or set of all cloud and atmospheric parameters that affect the measurement vector. In this equation, the quantity p pr ( x ), is known as the prior probability density function (pdf) of the state x . It represents our knowledge about the possible values of x before

@Meteorological Office, Bracknell, United Kingdom(Manuscript received 14 March 1994, in final form 14 February 1995)ABSTRACT Trajectory calculations are used to examine ozone transport in the polar winter stratosphere during periods ofthe Upper Atmosphere Research Satellite (UARS) observations. The value of these calculations for determiningmass transport was demonstrated previously using UARS observations of long-lived tracers. In the middle stratosphere, the overall ozone behavior observed by the Microwave Limb
