Assimilation of Long-Range Lightning Data Over the Pacific
Abstract
A Pacific Lightning Detection Network (PacNet) has been constructed with support from ONR and NASA. PacNet currently consists of four hybrid receivers, two sited in Hawaii, one in the Marshall Islands, and one in the Aleutian Islands (Fig. 1). Together the PacNet sensors continuously monitor sferics over the central Pacific Ocean and adjacent land areas. The long term goals of this and a follow-on project are to expand PacNet to cover the western Pacific Ocean with 8 additional sensors to be installed in 2008. In addition the project aims 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 COAMPS 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.
