Development of a New Videosonde Observation System for In-situ Precipitation Particle Measurements

摘要

References(25) Cited-By(4) Supplementary materials(1) A new videosonde receiving system consisting of two receiving antennas for a set of videosonde and GPS radiosonde has been developed. The antenna for the videosondes is controlled by a GPS slave method, in which the antenna elevation and azimuth are processed every second using GPS location data obtained from a GPS radiosonde attached to the videosonde. The results of the first experimental flight conducted in Okinawa as part of a synchronized observation campaign of a C-band polarimetric radar and videosondes reveal successful reception of clear images of precipitation particles in clouds.
