Abstract: The Arecibo Observatory recently began a regular program of coordinated tidal observations. Arecibo directly measures the ion velocity vector, the electron and ion temperatures, and the electron density over the 100–500 km region for this program. In addition, the ion neutral collision frequency can be inferred below 120 km. From these measurements neutral temperatures, the southward component of the neutral wind, and the eastward wind component below 130 km can be inferred. The height resolution is 2.3 km below 200 km, and 35 km above, while the time resolution is about 112 h for velocities and 30 min for temperatures. This paper describes the Arecibo measurements, and the method of analysis of the inferred neutral winds and temperatures for tidal components. Results for the initial observing period in August 1974 are presented.
