Abstract
Modification of the nighttime D region electron density (N-e) due to h eating by very-low-frequency (VLF) transmitters is investigated theore tically using a four-species model of the ion chemistry. The effects o f a 100 kW, a 265 kW, and a 1000 kW VLF transmitter are calculated for three ambient N-e profiles. Results indicate that N-e is reduced by u p to 26% at similar to 80 km altitude over a 1000 kW transmitter.
