GLD360 Performance relative to TRMM/LIS

16 October 2017

Vaisala GLD360 lightning observations are compared with total lightnign measurements made by LIS on the TRMM satellite.

Lightning Imaging Sensor flash counts during (a) 2012, (b) 2013, (c) 2014, and (d) 2012–14, along with the GLD360 stroke counts during (e) 2012, (f) 2013, (g) 2014, and (h) 2012–14. The color scale differs for (d) and (h), with colors representing 3 times the values depicted in (a)–(c) and (e)–(g). The limited LIS view time accounts for the much smaller LIS flash counts.

DCLMA Augmented Reality Viewer

One should never leave the safety of indoors during a lightning storm. This web-based project uses Augmented Reality methods to let users explore hazardous thunderstorms in the Washington, DC metro area without ever leaving the safety and comfort of home.

It uses a Python fork of the MINDEngine geoinformatics framework to create custom views of Lightning Mapping Array data on demand in real time so users can see the lightning developing all around them.

Mapping Lightning Flashes from Orbit

16 March 2017

Lightning imagers on satellites are useful for measuring total lightning production with a high detection efficiency. They can also be used to document the evolution of individual lightning flashes and probe their structure in some cases. This study uses Lightning Imaging Sensor (LIS) measurements to identify what level of spatial and temporal development that can be detected by lightning imagers.

The Evolution and Structure of Exceptional LIS Lightning Flashes

16 March 2017

The World Meteorological Organization (WMO) recently accepted new records for the longest length and longest duration of a single lightning flash. These record flashes were observed by Lightning Mapping Array (LMA) systems that monitor the VHF radio band for atmospheric sources. Lightning imagers provide a differing view on the properties and evolution of the flash. What are the flash extremes in the properties of optical lightning flashes?
