Microphysical and Dynamical Influences on Cirrus Cloud Optical Depth Distributions

Cirrus cloud inhomogeneity occurs at scales greater than the cirrus radiative smoothing scale (~100 m), but less than typical global climate model resolutions (~300 km). Therefore, calculating cirrus radiative impacts in global climate models requires an optical depth distribution parameterization. Radiative transfer calculations are sensitive to optical depth distribution assumptions (Fu et al...

Cirrus cloud optical and microphysical properties determined from AIRS infrared spectra

[1] We developed an efficient thermal infrared radiative transfer model on the basis of the delta-four-stream approximation to facilitate high-spectral-resolution remote sensing applications under cirrus cloudy conditions in the Atmospheric Infrared Sounder (AIRS) data. Numerical experiments demonstrated that sensitivity in the 800-1130 cm 1 thermal infrared window spectral region is sufficient...

Cirrus Microphysical Properties and Air Motion Statistics Using Cloud Radar Doppler Moments. Part I: Algorithm Description

The first three moments of the millimeter-wavelength radar Doppler spectrum provide valuable information regarding both cloud properties and air motion. An algorithm using these Doppler radar moments is developed to retrieve cirrus microphysical properties and the mean air vertical motion and their errors. The observed Doppler spectrum results from the convolution of a quiet-air radar reflectiv...

Cirrus cloud microphysical and optical properties at southern and northern midlatitudes during the INCA experiment

[1] Microphysical and optical measurements were performed in midlatitude cirrus clouds at temperatures between 33 C and 60 C during southern and northern Interhemispheric Differences in Cirrus Properties From Anthropogenic Emissions (INCA) field experiments carried out at equivalent latitudes (53 S and 55 N) from Punta Arenas in the Southern Hemisphere (SH, Chile) and Prestwick in the Northern ...
