We will introduce the results of our latest technology,which is used in measuring change in the atmosphere and ocean.

The Okinawa Electromagnetic Technology Center observes the movement of atmosphere and ocean and engages in research and development in the area of weather forecasting. In this exhibition booth our activities as well as our research and development will be explained. Take a moment to learn about the world's foremost global environment remote-sensing technology.

 Long-Range Ocean Radar

Long-Range Ocean Radar Observation of the ocean has traditionally been conducted by a buoy or a seagoing vessel. Long-Range Ocean Radar enables continuous long-term observation of a current situated approximately 200 kilometers offshore and demonstrates the connection between climactic changes and the ocean current.

The radar transmits high-frequency radio waves toward the ocean surface and receives backscattered signals from ocean waves. The device measures the frequency difference between the transmitted and received signals and the intensity of the received signal to determine surface current velocity, ocean surface wind direction, and the ocean wave conditions.

 Okinawa Bistatic Polarimetric Radar (COBRA)

NICT Okinawa Bistatic Polarimetric Radar (COBRA) This radar makes it possible to observe precipitation over a 300-kilometer-wide radius from a fixed point at a specific moment in time. Through our efforts this is the next generation of weather radar for observing precipitation and wind distribution in a rainfall area by means of six types of polarizations.

 400-MHz Wind Profiler Radar (WPR)

400-MHz Wind Profiler Radar (WPR) This is a remote-sensing device for measuring wind direction and velocity, and temperature in the atmosphere though observing changes in a high-altitude air current using radio and sound waves. It is possible to predict weather changes in a short period of time and to observe the development of a typhoon as well as climactic changes.

 Message Bottle Game

メッセージボトルゲーム You can play a radar game, the goal of which is to send a message bottle to a friend by releasing it into the ocean after checking the tide.
