AB: The World Wide Lightning Location (WWLL) system [Dowden et al., 2002] provides real time lightning locations globally by measuring the very low frequency (VLF) radiation emanating from lightning discharges. The location accuracy and efficiency of the WWLL have been estimated for certain regions of the globe [{\it Lay et al.}, 2004; {\it Rodger et al.}, 2004]. The FORTE satellite has monitored lightning within its field-of-view using radiofrequency and optical sensors [{\it Jacobson et al.}, 2000; {\it Kirkland et al.}, 2001; {\it Suszcynsky et al.}, 2000]. The signals recorded by FORTE have some capability to identify the lightning discharge process, e.g. ground stroke, intracloud stroke, or Narrow Bipolar Event [{\it Jacobson and Light}, 2003; {\it Jacobson and Shao}, 2002]. We will report on initial comparisons between WWLL and FORTE observations, conducted to gain more insights on the spatial and temporal accuracy of the WWLL as well as its ability to detect lightning discharges of various types.
