Modification of the nighttime D region electron density ( N e ) due to heating by very‐low‐frequency (VLF) transmitters is investigated theoretically using a four‐species model of the ion chemistry. The effects of 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 up to 26% at ∼80 km altitude over a 1000 kW transmitter.
