Colorado Lightning Mapping Array Data for GOES-R Satellite Validation

Three-dimensional total lightning activity data captured by the Colorado Lightning Mapping Array (COLMA) network during the GOES-R Post Launch Test airborne campaign. The dataset was produced by NASA to validate the Geostationary Lightning Mapper and Advanced Baseline Imager instruments on the GOES-R satellite. It covers a three-month period from March to May 2017.

Use Cases

• Validating Geostationary Lightning Mapper (GLM) detection algorithms by comparing satellite observations with ground-based 3D lightning source locations.
• Analyzing the spatial and temporal structure of lightning flashes within storms using mapped radiation source points.
• Studying the relationship between lightning activity and storm intensity or microphysics for meteorological research.
• Calibrating the Advanced Baseline Imager (ABI) cloud and precipitation products using co-located lightning activity as a physical indicator.

Strengths

• Data provides three-dimensional mapping of lightning radiation sources, offering detailed spatial structure.
• Dataset was collected during a dedicated field campaign (GOES-R PLT) for satellite instrument validation, ensuring focused scientific purpose.
• Covers a continuous three-month time range (March 1 to May 31, 2017) for seasonal analysis.

Limitations

• Exact data volume, row count, and column schema are unknown from available metadata.
• License information is unclear, with one source citing 'other-license-specified' and another providing no license.
