Correcting for Undercounting of Lightning Flashes by Space‐Based Optical Sensors

open access: yesJournal of Geophysical Research: Atmospheres, Volume 128, Issue 24, 27 December 2023., 2023
Abstract Accurate measurements of global lightning are essential for understanding present and future atmospheric electricity, composition, and climate. The latest space‐based lightning detector, the Geostationary Lightning Mapper (GLM), was the first to be placed in geostationary orbit, with a continuous view of most of the American continents.

Validation of the Geostationary Lightning Mapper With a Lightning Mapping Array in Argentina: Implications for Current and Future Spaceborne Lightning Observations

open access: yesEarth and Space Science, Volume 10, Issue 10, October 2023., 2023
Abstract A validation study of the Geostationary Lightning Mapper (GLM) on board the Geostationary Operational Environmental Satellite 16 (GOES‐16) was done using a ground‐based lightning mapping array (LMA) deployed as part of the Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations ...

Towards nowcasting in Europe in 2030

open access: yesMeteorological Applications, Volume 30, Issue 4, July/August 2023., 2023
An example for nowcast/very short‐range forecasting of rainfall using a combined observation and NWP‐based method by Météo‐France is provided, demonstrating the challenge of predicting convective‐scale system evolution in complex terrain (Cevennes region, South of France; panels (a–d) show nowcasts by this method for four timesteps within 3 h, (e–f ...

Day‐To‐Day Quantification of Changes in Global Lightning Activity Based on Schumann Resonances

open access: yesJournal of Geophysical Research: Atmospheres, Volume 128, Issue 11, 16 June 2023., 2023
Abstract The importance of lightning has long been recognized from the point of view of climate‐related phenomena. However, the detailed investigation of lightning on global scales is currently hindered by the incomplete and spatially uneven detection efficiency of ground‐based global lightning detection networks and by the restricted spatio‐temporal ...

Characteristics of Lightning Activities over the Tibetan Plateau Based on Satellite Detection and Its Circulation Background Analysis

open access: yesAtmosphere, 2023
Based on the detection data obtained by the LMI (Lightning Mapping Imager)—China’s first satellite-based lightning observation payload—from 2018–2022, combined with the ERA5 (ECMWF Reanalysis v5) reanalysis data of the same period, the temporal and ...

A Global LIS/OTD Climatology of Lightning Flash Extent Density

open access: yesJournal of Geophysical Research: Atmospheres, Volume 126, Issue 8, 27 April 2021., 2021
Abstract Previous lightning climatologies derived from Lightning Imaging Sensor (LIS) and Optical Transient Detector (OTD) total lightning measurements have quantified lightning frequency as a Flash Rate Density (FRD). This approach assumes that lightning flashes can be represented as points and quantifies the frequency of lightning centered in each ...

Preliminary Research on a Comparison and Evaluation of FY-4A LMI and ADTD Data through a Moving Amplification Matching Algorithm

open access: yesRemote Sensing, 2020
In this study, a new moving amplification matching algorithm was proposed, and then the temporal and spatial differences and correlation were analysed and evaluated by comparing the FengYun-4A Lightning Mapping Imager (FY-4A LMI) data and the China ...

Meteorological Satellite Operation Prediction Using a BiLSTM Deep Learning Model

open access: yesSecurity and Communication Networks, Volume 2021, Issue 1, 2021., 2021
The current satellite management system mainly relies on manual work. If small faults cannot be found in time, it may cause systematic fault problems and then affect the accuracy of satellite data and the service quality of meteorological satellite. If the operation trend of satellite will be predicted, the fault can be avoided.

Case Study of a Retrieval Method of 3D Proxy Reflectivity from FY-4A Lightning Data and Its Impact on the Assimilation and Forecasting for Severe Rainfall Storms

open access: yesRemote Sensing, 2020
As the first Geostationary Satellite with the LMI (Lightning Mapping Imager) instrument aboard running over the eastern hemisphere, FY-4A (Feng-Yun-4A) can better indicate severe convection and compensate for the limitations of radar observation in ...

Modeling the Transmission of Optical Lightning Signals Through Complex 3‐D Cloud Scenes

open access: yesJournal of Geophysical Research: Atmospheres, Volume 125, Issue 23, 16 December 2020., 2020
Abstract Space‐based lightning imagers have shown that complex cloud scenes consisting of multiple tall convective features, anvil clouds, and warm boundary cloud layers are illuminated by lightning in many different ways depending on where the lightning occurs and how energetic it is.
