Recent imaging observations with the Interface Region Imaging Spectrograp ( IRIS ) have revealed prevalent intermittent jets with apparent speeds of 80–250 km s ^ { -1 } from the network lanes in the solar transition region ( TR ) . On the other hand , spectroscopic observations of the TR lines have revealed the frequent presence of highly non-Gaussian line profiles with enhanced emission at the line wings , often referred as explosive events ( EEs ) . Using simultaneous imaging and spectroscopic observations from IRIS , we investigate the relationship between EEs and network jets . We first identify EEs from the Si iv 1393.755 Å line profiles in our observations , then examine related features in the 1330 Å slit-jaw images . Our analysis suggests that EEs with double peaks or enhancements in both wings appear to be located at either the footpoints of network jets , or transient compact brightenings . These EEs are most likely produced by magnetic reconnection . We also find that EEs with enhancements only at the blue wing are mainly located on network jets , away from the footpoints . These EEs clearly result from the superposition of the high-speed network jets on the TR background . In addition , EEs showing enhancement only at the red wing of the line are often located around the jet footpoints , possibly caused by the superposition of reconnection downflows on the background emission . Moreover , we find some network jets that are not associated with any detectable EEs . Our analysis suggests that some EEs are related to the birth or propagation of network jets , and that others are not connected to network jets .
