Opportunities for Observing and Sensing Atmospheric Electromagnetic Anomalies RFI

Excerpt:  “The Intelligence Advanced Research Projects Activity (IARPA) seeks information regarding innovative signal processing algorithms and sensing approaches used to characterize the D-region of the ionosphere (60–90 km). IARPA seeks to characterize and better understand the D-region and the interaction of this region of the ionosphere with electromagnetic (EM) anomalies caused by space weather events, lightning, manmade sources, etc. and whether the resulting D-region characterization can be used to identify, map, and track these EM anomalies”
