Oklahoma Lightning Mapping Array Data from GOES-R Post-Launch Test

This dataset provides a three-dimensional map of total lightning activity captured by the Oklahoma Lightning Mapping Array (OKLMA) network during the GOES-R Post Launch Test airborne field campaign. The data was collected to support validation of the Geostationary Lightning Mapper and Advanced Baseline Imager instruments on the GOES-R satellite. It consists of compressed ASCII files containing source location and timing data from March 1 to June 1, 2017.

Use Cases

• Validating Geostationary Lightning Mapper (GLM) satellite observations against ground-based 3D lightning source locations.
• Analyzing the spatial and temporal evolution of lightning discharges within storm systems over Oklahoma.
• Studying the relationship between total lightning activity and severe weather phenomena during the spring season.
• Correlating lightning source data with other airborne or ground-based meteorological measurements from the field campaign.

Strengths

• Provides 3D source location data for total lightning, enabling detailed spatial analysis of discharges.
• Covers a focused 3-month time period (March-June 2017) during a dedicated satellite validation campaign.
• Data is hosted on multiple authoritative platforms (NASA Earthdata and Data.gov), indicating recognized importance.

Limitations

• Column names and specific data structure are not documented in the provided metadata.
• Sources conflict on license information (other-license-specified vs. None) and last updated date (2026 vs. 2017).
• Exact file size and row count are unknown, limiting assessment of dataset scale.
