             abstract = "The Upward Lightning Triggering Study (UPLIGHTS) is a three-year 
                         National Science Foundation-funded field project that is taking 
                         place in Rapid City, South Dakota, from April 2012 to September 
                         2014. Three upward flashes that occurred within a 20-min period 
                         were all triggered by a preceding +CG (cloud-to-ground) flash. In 
                         each case, in-cloud brightening following the +CG propagated 
                         toward the towers prior to upward leader initiation. Supporting 
                         electric-field data suggested that the approaching in-cloud 
                         brightening was horizontally propagating negative-leader 
                         development occurring during the +CG continuing current, and that 
                         the electric-field change created by the approaching negative 
                         leaders caused the initiation of upward positive leaders from the 
                         towers. Although none of the 10 towers had current sensing 
                         instrumentation, it is likely that a large majority of the upward 
                         flashes were upward negative lightning. The research may result in 
                         improved detection of upward lightning by lightning location
