In this paper, microwave scattering was utilized to measure the electron number density produced in a nanosecond-long high-voltage breakdown of air between two electrodes in a pin-to-pin configuration. The approach allows tracing the absolute electron number in the plasma volume during the high-voltage pulse and the plasma decay for wide range of plasma and discharge parameters. Lastly, electron number density decayed on the timescale of about several μs governed by plasma-chemical processes including dissociative recombination, three-body attachment and formation of cluster ions.
