mature and re-intensifying stage. After Zhao {1994}.
Future systems could overcome these difficulties. The next scatterometer in space, NSCAT
on the Japanese ADEOS satellite with launch date in August 1996, will have two swaths and
thereby intercept most cyclones once per day (except at the Equator). Transfers of SSM/I
data are improving over more efficient internet pathways. A general trend towards optimal use
of several sensors on one or several satellites was also illustrated with the examples presented
above. Combined use of visible, infrared and microwave data gives improved choice of liquid
water path algorithms for strato-cumulus clouds. Multiple sensors allow more opportunities to
