In November 1975, typhoon June formed in the Philippine Sea and was observed by the scanning microwave spectrometer on the Nimbus 6 satellite. This instrument measures thermal radiation emitted by the earth in the microwave band of oxygen, a water vapor line, and a transmittance window in between. The oxygen band measurements provide temperature maps, which show a single peak at the eye of the typhoon that changes in amplitude with time. The water line and window measurements are transformed into a coordinate system in which the atmospheric variables of column water vapor content and cloud liquid water content are mutually orthogonal. The vapor showed a broad maximum around the typhoon while it was intensifying. More structure developed in the vapor as the typhoon weakened. Inside the typhoon, surface roughness and white water induced by the wind are evident in the measurements. By assuming that the troposphere was saturated with respect to water vapor inside the typhoon, surface wind speed and cloud liquid water content are inferred. The temperature and the wind inferred from the microwave measurements show time and space correlations that are expected in light of the thermal wind equation. Comparisons are made with infrared cloud imagery and aircraft reconnaissance flight data. In the microwave-aircraft data comparison the corresponding parameters show somewhat different time variation, which we attribute to the fact that the eye of the typhoon was not resolved in the microwave images.
