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 Full Disk Data Quality | Performance variability, sources of false flashes, and additional data quality considerations when using full disk GLM products. |
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. |
GLM Minimum Flash Area (MFA) | This provides an overview of Minimum Flash Area (MFA), which reports the minimum size of any GLM flash spatially coincident with each 2×2 km grid cell during a specified time period. |
GLM Full Disk Gridded Products | This provides an overview of GLM Full Disk Gridded products and applications. |
