Forward-Looking Digital Camera Imagery. Version 1.0

During NOREASTER, the GV_N677F flew a forward looking digital camera for in-flight video capture. Individual photo jpeg images were captured once per second during flights. Images taken after dark have been stripped from this archive. The remaining images have been combined into hour long tarfiles running from zero minutes zero seconds (or the start time of the first file) to 23 minutes 59 seconds (or the end time of the last file) after each hour. Note that the first and last tarfile for each flight will contain less than a full hour of imagery. Directory files returned with each order give the contents of each corresponding tar file.

在NOREASTER任务期间，GV_N677F搭载了一台前视数码相机，用于飞行中的影像采集。飞行过程中，系统每秒捕获一张JPEG格式的单幅照片。本数据集已剔除所有夜间拍摄的图像。剩余图像被整合为按小时划分的tar打包文件，每个打包文件的时间覆盖范围为对应小时的0分0秒（或首个文件的起始时刻）至23分59秒（或最后一个文件的结束时刻）。需注意，每次飞行的首个和最后一个tar打包文件所包含的影像时长不足一小时。随每份订购交付的目录文件，将列明每个对应tar打包文件的具体内容。
