Lightning‐Produced Nitrogen Oxides Per Flash Length Obtained by Using TROPOMI Observations and the Ebro Lightning Mapping Array [PDF]
Geophysical Research Letters, 2023 Lightning is one of the main sources of NOx in the Earth's atmosphere. However, there is a large variability in NOx production during the lifetime of thunderstorms.

Spatio-temporal dimension of lightning flashes based on three-dimensional Lightning Mapping Array [PDF]
Atmospheric Research, 2017 3D mapping system like the LMA - Lightning Mapping Array - are a leap forward in lightning observation. LMA measurements has lead to an improvement on the analysis of the fine structure of lightning, allowing to characterize the duration and maximum extension of the cloud fraction of a lightning flash.

Imaging lightning intracloud initial stepped leaders by low‐frequency interferometric lightning mapping array [PDF]
Geophysical Research Letters, 2016 By comparing the source position of pulses during initial leaders and the paths of subsequent dart leaders from typical bilevel intracloud (IC) flashes, we demonstrate a new method to image the detailed three‐dimensional (3‐D) structure and stepping ...

High altitude leaders mapped by the Colombia lightning mapping array [PDF]
, 2016 On April 2015 a Lightning Mapping Array network (COL-LMA) was installed at the north of Colombia. This network provides 3D mapping of the development of lightning leaders. For the first time such network has been setup in the tropics. That allows us to investigate the high altitude development of lightning leaders.

Diurnal characteristics of lightning flashes detected over the São Paulo lightning mapping array [PDF]
Journal of Geophysical Research D: Atmospheres, 2015 AbstractThis study examines diurnal variations of lightning flash characteristics observed by the Lightning Mapping Array in São Paulo, Brazil. The diurnal flash counts exhibit the typical afternoon convective maximum. The mean source altitude demonstrates a discrete increase that is temporally coincident with the local sunrise. The mean horizontal and

Basic lightning flash properties derived from lightning mapping array data [PDF]
, 2016 The size and duration of lightning flashes are examined. Data from the Ebro Valley Laboratory Lightning Mapping Array is used as reference. Additional data from the VLF/LF LINET network is included. In the analysis, each flash is simplified by a confidence ellipse fitting most of the detected sources.
