PEM Tropics Video Tapes VHS video tapes have been placed in the GTE archive for the PEM Tropics mission. The following table indicates the tapes available. Video cameras were placed aboard each aircraft to monitor surrounding clouds. A camera was placed in the cockpit and was aimed about 45 deg. upward to view clouds in the forward direction. Likewise, cameras were aimed upward and downward from the aircraft to view clouds in the zenith and nadir directions. The zenith view was often of limited value because of sun glint in the wide angle lens. Video cameras were also placed aboard the aircraft to record the scope display of the Weather Radar(DC-8) and the Storm Scope. Appendix B of the PEM Tropics Expedition Plan provides descriptions of all the video camera installations and the Storm Scope and Weather Radar.

N. Krishnamurti since the mission based upon his modeling efforts. The video provides wind field and rainfall animation over the Pacific at 1000 mb, 850 mb, 500 mb, and 200 mb. Also included are air parcel trajectories for flights 10P at 850 mb, 12P at 500 mb, 13P at 500 mb, 9D at 200 mb, 14D at 300 mb, and 17D at 850 mb. The tapes are available on loan by contacting Jim Raper at j.l.raper@larc.nasa.gov. Copies may also be requested for retention.
