Downward and Forward-Looking Digital Camera Movies with data [. Version 1.0

During NOMADSS, the NCAR C-130 flew both forward and downward looking digital cameras 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. Remaining forward and downward images for each second were combined into a single image and processed to include production data along the right side of the image and converted to Quicktime movie files. The movies are h.264 codec playable with Quicktime (Mac and Windows), xine, (linux) and mplayer (many platforms). The original images are 1024x768 pixels and were recorded at 1 frame/second. The multi-frame movies are set to play back at 712x768 pixels and 15 fps.

在NOMADSS项目执行期间，NCAR的C-130航空器搭载了前视与下视数码相机，用于飞行中视频采集。飞行过程中，每秒采集一张单张JPEG（Joint Photographic Experts Group）图像。本数据集已剔除夜间拍摄的图像。将每一秒留存的前视与下视图像合成为单张图像，经处理后在图像右侧附加生产数据，并转换为Quicktime影片文件。该系列影片采用h.264编码格式，可通过Quicktime（适配Mac与Windows系统）、xine（适配Linux系统）及mplayer（适配多平台）播放。原始图像分辨率为1024×768像素，采集帧率为1帧/秒。多帧影片的播放分辨率设定为712×768像素，播放帧率为15帧/秒。
