Okinawa Electromagnetic Technology CenterThe Okinawa Electromagnetic Technology Center is currently conducting research and development into 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 are also conducting additional atmospheric and oceanic observations, mainly in the maritime subtropical climate zone.

Long-Range Ocean Radar Ishigaki/Yonaguni Ocean Radar Facility

Long-Range Ocean Radar Ishigaki/Yonaguni Ocean Radar FacilityThe Long-Range Ocean Radar system, which is composed of two radars located on Ishigaki Island and Yonaguni Island in Okinawa, is a new ocean remote-sensor. We had continued not only the radar performance evaluations but also experimental observations of the Kuroshio current in the East China Sea. Because we completed our research and achieved our goals, we removed the Ishigaki radar in 2010 and currently obtain data only from Yonaguni radar.

Winds 400-MHz/1.3-GHz Wind Profiler Ogimi Wind Profiler Facility Ocean

Ogimi Wind Profiler FacilityThis is an experimental observation facility for the development of atmospheric remote sensors designed for practical use. To this end, various atmospheric sensors are currently being operated in combination to evaluate their performance and to further develop new methods of atmospheric observation.

NICT Okinawa Bistatic Polarimetric Radar (COBRA) Nago Precipitation Radar Facility and Bistatic Receiver Station

Nago Precipitation Radar Facility and Bistatic Receiver StationThe 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.

The Computer Network System for Subtropical Environment Monitoring Rain

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

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.
