MethaneAIR: Forward-Looking Digital Camera Imagery. Version 1.0

During MethaneAIR, the NSF/NCAR HIAPER GV (Tail Number 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. Forward-looking camera images are available for Phase 1 of MethaneAIR (RF01 and RF02).在甲烷空中观测项目（MethaneAIR）执行期间，NSF/NCAR的HIAPER GV型科研飞机（尾号N677F）搭载了用于机载视频采集的前视数码相机。飞行过程中，每秒采集一张JPEG格式的单张照片。夜间拍摄的图像已从本归档数据集中移除。剩余图像已被打包为每小时一档的tar归档文件，每档覆盖对应小时的0分0秒（或首个文件的起始时间）至23分59秒（或末个文件的结束时间）区间。请注意，每次飞行的首个和末个tar归档文件所包含的影像时长不足一小时。每份订单附带的目录文件会列出对应tar归档文件内的文件清单。该项目第一阶段（RF01与RF02）可提供前视相机图像。
