Comparison & characterisation of ATDnet versus LIS
This study evaluated the performance of the UK Met Office lightning location system ATDnet against the Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensor (LIS) for the period 2008 to 2014.

The detection efficiency (DE) of the Met Office long-range Very Low Frequency lightning location system ATDnet was evaluated against the Tropical Rainfall Measuring Mission Lightning Imaging Sensor (LIS) during 2008-2014, within the LIS data domain (38°N-38°S; 180°W-180°E).
ATDnet detected 20-30% of LIS flashes over the Mediterranean and the east Atlantic, 10-15% of LIS flashes over the west Atlantic and 5-10% in northern and western Africa. ATDnet DE was notably higher over salty water compared to land. The average number of ATDnet strokes/pulses per detected LIS flash was 1.23 and 15% of the detected LIS flashes had more than one ATDnet observation. ATDnet detected stronger LIS flashes more efficiently, with a high number of events per group and large area.

ATDnet network redesign feasibility study
This study examined the Met Office lightning location network (ATDnet) with respect to requirements for the forthcoming Meteosat Third Generation (MTG) Lightning Imager (LI) instrument.
Comparison of ground-based LLS network data to ISS-LIS in MTG LI domain
This study compares data from the Lightning Imaging Sensor flown on the International Space Station (ISS-LIS) with various ground based lightning detection systems, in preparation for the Lightning Imager (LI) onboard the Meteosat Third Generation Imaging satellite (MTG-I).
