Left-Looking Digital Camera Imagery. Version 1.0

During CONTRAST (CONvective TRansport of Active Species in the Tropics), the NSF/NCAR GV HIAPER (Gulfstream-V High-performance Instrumented Airborne Platform for Environmental Research) flew a left-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. Note: Forward, Downward, and Right-looking images can be found in the companion datasets.

在‘热带活性物种对流输运（CONvective TRansport of Active Species in the Tropics，CONTRAST）’科考项目期间，美国国家科学基金会（NSF）与国家大气研究中心（NCAR）联合运营的湾流V型高性能机载环境研究探测平台（Gulfstream-V High-performance Instrumented Airborne Platform for Environmental Research，HIAPER）搭载了一台左视数码相机，用于机载视频采集。飞行过程中，该相机以每秒1帧的速率采集单张JPEG格式照片。本数据集归档已剔除夜间拍摄的所有影像，剩余影像被整合为按小时划分的tar归档文件，每个归档文件的时间范围为每小时的0分0秒（或首个归档文件的起始时刻）至23分59秒（或末个归档文件的结束时刻）。需注意，每次飞行任务的首个与末个tar归档文件所包含的影像时长不足1小时。随每份订单返回的目录文件可列明对应tar归档文件的具体内容。注：正向、向下及右视相机拍摄的影像可在配套数据集中获取。
