The continuous DITF acts as a very complementary instrument to the Langmuir lightning mapping array (LMA). The LMA locates lightning in 3D by measuring the arrival time of VHF lightning emissions in 10 microsecond windows at several locations around Langmuir Laboratory. The LMA and interferometer data can be combined such that the 2D interferometric image is projected onto the 3D LMA locations. The resulting 3D image improves upon the data provided by either system alone. Ambiguities in the interferometer data arising from sources moving towards or away from the interferometer are removed. The timing resolution of the LMA is improved to that of the interferometer. Continuously radiating emissions such as K-changes and dart leaders can be mapped in 3D. The combined continuous DITF and LMA system is proving to be a very powerful tool for the study of lightning electrical breakdown processes.
To demonstrate the capabilities of the continuous DITF, results from a handful of classic bilevel intra-cloud and cloud-to-ground flashes are presented.
