Mid-Atlantic Lightning Mapping Array (MALMA) Raw Data
Listed in NASA Earthdata CMR
The Mid-Atlantic Lightning Mapping Array (MALMA) dataset collection is used to validate the Lightning Imaging Sensor (LIS) on the International Space Station (ISS), the Geostationary Lightning Mapper (GLM) instrument, and other current and future lightning measurements.
Description
These data are also used in convective storm process studies, including but not limited to the validation of convection-resolving models that predict lightning.
The MALMA network is obtained through the combined processing of two separate lightning mapping arrays. These are the Washington D.C. lightning mapping array (DCLMA) and the Wallops Flight Facility lightning mapping array (WFFLMA). The individual output for these networks are available as separate products and are listed in the Related Data section.

The raw files provide the output from the individual sensors. The MALMA data files are available from January 1, 2020 through April 4, 2026 and are ongoing in ASCII format.
