The Okinawa Electromagnetic Technology Center conducted research and
development for three types of radio sensors. Our objective is to
investigate the mechanisms of interaction between the ocean and the
atmosphere, as it is well known that this interaction significantly
affects global-scale climatological variations such as global warming.
We also conducted additional atmospheric and oceanic observations,
mainly in the maritime subtropical climate zone.
In 2014, phased array weather radar and doppler lidar network fusion
data system (PANDA) and Space optical communication system were completed.
The sudden, local weather disasters caused by localized bursts or tornados
have been huge social issues. It is very important to investigate the 3D
structure of precipitating cloud for the early detection, however, the
conventional radar with parabola antenna could not correspond. Adopting
the 1D phased array into this radar system improved the time resolution
of observation dramatically.
This is an optical reflecting telescope used for space optical communication
that makes the high-speed communication possible. This telescope can observe
with 4 focuses including Nasmyth and Coude focus in addition to Cassegrain
reflector, and tracks LEO satellite with a high degree of accuracy.
The Okinawa Bistatic Polarimetric Radar is being developed to perform high-precision measurements of meteorological phenomena in the subtropical region, such as the three-dimensional structure of precipitation and winds accompanying typhoons. The results of this development will be used to verify the practicability of next-generation precipitation radar technologies.
This is a computer network for the automatic acquisition, accumulation, and distribution of atmospheric and oceanic observation data collected at the Ogimi Wind Profiler Facility (NICT Ogimi), the Nago Precipitation Radar Facility (NICT Nago), the Ishigaki Ocean Radar Facility (NICT Ishigaki), the Yonaguni Ocean Radar Facility (NICT Yonaguni), and the Okinawa Electromagnetic Technology Center (NICT Okinawa).
The ground-based meteorological observation system consists of three observation stations ( which are located in Ogimi, Nago, and Onna) and one monitoring station for surveillance and control of the observation stations. The system permits continuous ground-based observations of meteorological characteristics such as temperature, humidity, atmospheric pressure, wind direction, wind speed, solar radiation, and precipitation.
