Assimilation of Long-Range Lightning Data Over the Pacific
Abstract
A Pacific Lightning Detection Network (PacNet) has been constructed and expanded with support from ONR. PacNet currently consists of seven hybrid receivers. The sensors are sited in Kauai, Island of Hawaii, Unalaska, Kwajalein, Guam, Papua New Guinea, and Okinawa. In addition, a sensor will be installed in the Philippines in November 2008 (Fig. 1). The sensor in Kwajalein currently has communications issues that will be resolved in the near future. These sensors work together with the North-American Lightning Detection Network sensors located in the U.S. and Canada to form a network called PacNet/Long-Range Lightning Detection Network (PacNet/LLDN). Together the PacNet/LLDN sensors continuously monitor sferics over the Pacific Ocean and adjacent land areas. In addition, the project supports operational utilization of the data stream at NRL for (i) nowcasting convective activity, (ii) convective rainfall analyses over the Pacific, and (iii) to improve marine prediction of cyclogenesis and squall-line motion through sferics data assimilation in COAMPS and NOGAPS. Technology transfer to NRL will be accomplished in close collaboration with NRL scientists, with data processing and analysis support from University of Hawaii (UH) and Vaisala scientists.
