Assimilation of Long-Range Lightning Data over the Pacific
Abstract
Pacific Lightning Detection Network (PacNet) has recently been constructed with support from ONR and NASA. PacNet consists of five hybrid receivers, two sited in Hawaii, one in the Marshall Islands, one in the Aleutian Islands, and one to be installed on Christmas Island (Fig. 1). Together the PacNet sensors continuously monitor sferics over the central Pacific Ocean and adjacent land areas. The long term goals of this project are to continue development of PacNet and to support 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 COAMP and NOGAPS. Technology transfer to NRL will be accomplished in close collaboration with NRL scientists, with data processing and analysis support from Vaisala and NASA scientists.
