Abstract:

Reentry weather encountered by Minuteman test PVM-5 is described. Documentation was accomplished by WB-57F aircraft, by satellite, by radar, and by lidar. All RVs passed through a cloud layer with maximum ice water content of 0.03 to 0.08 gmcu m. Weather Severity Indices were 0.8, 0.6, and 0.3 for RV1, 2, and 3. Precise definition of the reentry weather was made possible by correlation of simultaneous weather measurements by aircraft and radar after the reentry. These measurements were performed by means of the link-offset mode, in which the radar weather data were recorded at a fixed distance ahead of the aircraft.
