The primary objective of the Experimental Warning Program (EWP) is to evaluate the accuracy and the operational utility of new science, technology, and products in a testbed setting in order to gain feedback for improvements prior to their potential implementation into National Weather Service (NWS) operations (see Stumpf et al, this conference). A developmental product for the GOES-R Geostationary Lightning Mapper (GLM) was demonstrated during the Spring 2010 EWP as part of the GOES-R Proving Ground. This product was created using data from ground-based Lightning Mapping Array (LMA) networks sorted into flashes and displayed at the 8 km resolution expected with the GLM.

During the EWP, forecasters were able to examine the lightning data in AWIPS in conjunction with radar and other multi-sensor products as part of their warning-decision process for both real-time and archive events. Forecasters were then asked to provide feedback through both online surveys following the event and also through discussion with lead scientists. This feedback will help shape the design of the products and educational tools concerning lightning data ahead of the availability of GOES-R data in the local NWS offices. In addition to the individual forecaster feedback, all warnings issued by the forecasters during the EWP have been scored (POD, FAR) and compared with the official NWS warnings to determine what type of influence the GOES-R products may have had on the warning decision process as well as on warning polygon size and location.
