Figure Caption:

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.

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

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)...

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...

The baseline 20 km run of the Peterson et al. (2015) electric field retrieval algorithm on the Tropical Rainfall Measuring Mission (TRMM) dataset is used to rank the three tropical chimney regions. Unlike previous studies that have looked only at land-based thunderstorms, we consider...

A database of Radar Precipitation Features (RPFs) is constructed for electrified clouds. This Electrified Cloud Features (ECF) database includes only those RPFs with pixels that the Tropical Rainfall Measuring Mission (TRMM) passive microwave electric field algorithm considers to be electrified...
