Development of a 400 MHz-band Wind Profiler Radar with RASS

摘要

Okinawa Subtropical Environment Remote-Sensing Center of the Communications Research Laboratory has developed a new 400 MHz-band Wind Profiler Radar (400M-WPR) since FY 1997 in a research and development project of remote-sensors for measuring subtropical environment. After construction of the Ogimi Wind Profiler Facility at Ogimi village in Okinawa, the 400M-WPR has continued wind velocity profiling with an altitude range from approximately 400 rn to typically 13 km, and with an interval of a few minutes. We were successful for the wind profiling up to 16 km near the center of a typhoon Nari approached in September 2001. Besides, a RASS attached to the 400M-WPR could obtain virtual temperature profiles up to about 3 km.
