Evidence of nonspheroidal behavior in millimeter-wavelength radar observations of snowfall

[1] Recent modeling results have indicated that, in general, idealized homogeneous spheroidal models of ice crystals and snowflakes cannot consistently describe radar backscattering from snowfall when the radar wavelengths are on the order of the snowflake size. In this paper, we provide empirical evidence supporting this prediction by analyzing collocated airborne radar measurements at 13.4 GH...

Millimeter-wave stratocumulus LWP retrievals

Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract A unique feature of the VOCALS Regional Experiment was the inclusion of a small, inexpensive, zenith-pointing millimeter-wavelength passive radiometer on the fourteen rese...

Millimeter - Wavelength Spectroscopy

Millimeter-wavelength spectra were obtained of CO, HCN, H2CO, and CH3OH in Comet C/1996 B2 (Hyakutake) with the NRAO 12-m telescope on 21 Mar 1996 UT. The emission of CO, H2CO and HCN was mapped in the coma when the comet was 0.2 AU from the Earth, providing a detailed look at the behavior of these species in the inner coma. The mapping data indicate the presence of multiple velocity components...
