94 GHz Doppler spectra in cirrus

Robin Hogan, 25 Sept 1998

This page presents some preliminary observations of the spectra of ice crystal fall speeds in cirrus, taken on 21 August 1998, shortly after the 94-GHz radar was Dopplerised. The following two figures (click for gzipped Encapsulated Postscript file) show vertical profiles of Doppler spectra taken 20 seconds apart (time-series files 21163556.098 and 21163617.098), together with the vertical profile of signal-to-noise ratio.
