North Alabama Lightning Mapping Array Data for Storm Studies

December 17, 2019 to present, this dataset contains lightning mapping array data from North Alabama. It is used to validate space-based lightning sensors like the ISS LIS and GOES GLM and for convective storm process research. The data is provided by the Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) and is ongoing.

Use Cases

• Validating lightning detection from the International Space Station Lightning Imaging Sensor (ISS LIS).
• Calibrating and assessing data from the Geostationary Lightning Mapper (GLM) instrument.
• Studying convective storm processes and electrification.
• Providing ground-truth data for convection-resolving weather models that predict lightning.

Strengths

• Provides continuous temporal coverage from December 2019 to the present, supporting longitudinal studies.
• Serves as a critical validation source for multiple current and future satellite lightning measurement systems.
• Data is hosted and maintained by the authoritative NASA GHRC DAAC.

Limitations

• Specific column names, row counts, and file sizes are not disclosed in the available metadata.
• License information is inconsistently reported as 'other-license-specified' or null across sources.
