Abstract

We conducted 1-month long observation with Cloud Image Velocimetry (CIV) at Kagurazaka, Tokyo. Cumulus and cirrocumulus, whose boundary has clear brightness values, are found to be highly applicable in CIV. On the other hand, stratus which has unclear boundary was found to be difficult to apply CIV. Wind speeds observed with CIV was compared with rader velocity obtained by Ka-band cloud radar, and reasonable correlation were found between them.
