CEPEX: NASA ER-2 Digitized Cloud Video. Version 1.0

This dataset contains cloud videos. The files are mpeg video files digitized from VHS format video tapes which were recorded from a downward-looking video camera system mounted on the NASA ER-2 during the Central Equatorial Pacific Experiment (CEPEX). One video tape has been recorded per mission, for a total of 13 videos. The rf10 video (3/28) is not available due to problems with the original recording. On some of the videos the on-screen display reads the year 1992 when it should be 1993. All videos between (and including) dates 3/12/93 - 3/31/93 read one day ahead of what they should be on the on-screen dislplay, however, the actual dates can be read from the file names. F-stop varied per mission with shutter speed set at 1/2000 per sec. This includes cloud video.本数据集包含云视频素材。所有文件均为从VHS格式录像带数字化得到的MPEG视频文件，该录像带由搭载于NASA ER-2飞机的朝下式摄像系统录制，录制时段为赤道中太平洋实验（Central Equatorial Pacific Experiment, CEPEX）期间。每次任务对应一盘录制录像带，总计13段视频。其中rf10视频（对应日期3/28）因原始录制故障无法获取。部分视频的屏幕显示年份为1992年，但实际应为1993年；日期处于1993年3月12日至1993年3月31日（含首尾）的所有视频，屏幕显示的日期均比实际日期快1天，但实际日期可通过文件名直接读取。每次任务的光圈值（F-stop）存在差异，快门速度均设置为1/2000秒。本数据集收录的全部内容均为云视频素材。
