Figure: The International Space Station Lightning Imaging Sensors 128 X 128-pixel array of (a) event count, (b) total event energy density, (c) mean event energy density, (d) pixel minimum energy density, (e) pixel maximum energy density, and (f) pixelwise 95% quantile energy density during March 2017–September 2020, computed separately for each pixel, indexed by CCD pixel numbers.

Evaluating Lightning Observations from Space

ESSIC/CISESS Scientists Daile Zhang, Scott Rudlosky (NOAA), and colleagues published a study that uses the well-documented Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensors (LIS) performance to determine if the International Space Station (ISS) LIS performs well enough to bridge the gap between TRMM LIS and the new generation of Geostationary Lightning Mappers (GLMs).

Building & Deploying Tools to Better Observe Lightning in the Washington D.C. Region & Beyond

In January 2022, ESSIC/CISESS Scientist Daile Zhang won a CISESS Seed Grant to evaluate NOAA’s Geostationary Lightning Mappers (GLMs) on the GOES-16 and -17 Satellites and the upgraded Mid-Atlantic Lightning Mapping Array (MALMA) using a network of low-cost and innovative atmospheric electricity and lightning measurement tools to take lightning videos. Recently, the initial Seeds Grant period ended and Zhang reported her results.

Daile Zhang Speaks at the International Conference on Lightning Protection

ESSIC/CISESS Scientist Daile Zhang is a coauthor of a presentation that was given at the 36th International Conference on Lightning Protection in Cape Town, South Africa during October 2-7, 2022. She has published a conference paper, which was presented by the co-author Ron Holle, a former meteorologist for Vaisala as well as NOAA. The paper is titled “The Epidemiology of Lightning in Mainland China – A Review of Two Datasets from the 1950s to 2018.”

Lightning as an Indicator of Climate

ESSIC/CISESS scientist Daile Zhang attended and presented at the National Climate Assessment (NCA) “Lightning as an Indicator of Climate” Annual Science Meeting that was held on June 6-7 at the UMD Department of Atmospheric and Oceanic Science (AOSC) Atlantic Building. The meeting is an annual working group get-together for people from NASA, University of Arizona, City College of New York, University of Alabama in Huntsville, and University of Maryland on various lightning tasks/projects, including lightning climatology, lightning NOx observations, dry lightning, wildfires, and this year’s NASA Marshall Space Flight Center CubeSpark project.
