Don: This letter is to voice my strong support for NCAR's acquisition of video projectors for the seminar rooms at the Mesa and Foothills Labs. The use of video animations is an increasingly important tool for time-dependent studies of our model results. We have developed a series of animations on video tape which will be shown at the CEDAR science meeting later this month, and for which we are renting a video projector. We would use video projectors in the NCAR auditoriums to show time sequences of model results at seminars and science discussions. Ray Roble ncar/hao
