Cirrus cloud ice water path
Webmeasurements of water path and large particle sizes in ice clouds. These spectra are also insensitive to liquid water so that the signal from the cirrus clouds can be isolated. Infrared interferometers may also yield new insight into cirrus microphysics (Smith et al., 1993). Thus, future monitoring systems may carry a wide array of instruments that WebCirrus cloud layers are in general statically stable in an absolute sense, with lapse rates less than the moist-adiabatic rates with respect to either water or ice. Some cirrus …
