The problem of allowing for the influence of the Earth's magnetic field on brightness temperatures in retrieving mesospheric information by use of microwave radiometric measurements is considered. A physically based method for incorporating magnetic field effects within an otherwise linear regression procedure is developed. The resulting algorithm is fast enough to be used operationally for a satellite-borne scanning radiometer system. Error statistics obtained for a small database indicate that considerable improvement over climatological estimates of the state of the mesosphere will be possible up to at least the 0.03-mb level (roughly 73-km altitude)
