GLM Quick Guides

Name Description
GLM and Ground-Based Networks              This is a quick guide highlighting the strengths and differences between the Geostationary Lightning Mapper and the ground-based lightning detection networks.
GLM Applications This provides an overview of the advantages, limitations, and potential uses of the Geostationary Lightning Mapper's flash extent density product.
GLM Detection Methods The GLM creates background images every 2.5 minutes, then images 500 frames per second to detect changes in brightness relative to the background image. Individual pixels that are illuminated above the background threshold during a 2 ms frame are termed GLM events, filters then determine the likelihood that these events are real lightning.
GLM Data Quality Issues described include geospatial considerations and false events.
GLM Gridded Products/FED Flash extent density (FED), the number of flashes that occur within a grid cell over a given period of time, is the first NWS gridded GLM product.
GLM Gridded Products/AFA and TOE Average flash area (AFA) is the average area of all GLM flashes spatially coincident with each 2×2 km grid cell during a specified time period. Total optical energy (TOE) is the sum of all optical energy that the GLM observes within each grid cell during a specified time period.

Cloud Top Pressure Baseline Cloud Top Pressure estimates the cloud top pressure (in hPa). Values are not assigned in clear skies.
Cloud Top Temperature The Baseline Cloud Top Height Temperature estimates the temperature of the cloud top in degrees Celsius; it is generally more accurate than individual channel Brightness Temperatures that can be affected by absorption by gases.
