high-altitude nuclear electromagnetic pulse (HA-NEMP)

High-Alitude Nuclear Electromagnetic Pulse(HA- NEMP) is a nuclear electromagnetic pulse detonated outside the atmosphere.

Such a HA-NEMP pulse has a blast height between 30 km and 40 km above the ground and a continental effect. The use of HA-NEMP pulses can thus affect the electronics of entire continents. TREE, Transient Radiation Effects on Electronics, addresses the impact and effect on electronic components and devices.

Nuclear pulses near the ground are referred to as Low-Altitude Nuclear Electromagnetic Pulses (LAEMP).
