Abstract: We studied data from the global AWDANet plasmasphere monitoring network for whistlers detected locally, distorting the general statistics of whistlers. Our preliminary results show that apart from the geomagnetically conjugate hemisphere as a potential source region, local lightning generated in the vicinity of the whistler detector stations should also be considered. Our results can improve on the daily and seasonal statistics of whistler occurrence, and locally generated whistlers can contribute to a more complete monitoring of the plasmasphere.
