Motivation for developing recoverable radiosonde systems...
Two strategies to recover radiosondes
ìYo-Yoî sonde mode
High soundings- less spatial resolution at any particular level
Shallow soundings - better horizontal resolution at any level
Over-ocean powersonde... Value is to make observations where other systems cannot
Island effects can produce unrepresentative measurements - would be nice to make soundings away from islands or coastlines...
North American Monsoon Experiment (2004 summer)
Diurnal variation of winds smaller on small islands than on big islands or on coastlines...
