机载数字大气数据系统(DADS)如何记录和呈现飞机的高度、俯仰角和滚转角信息?
CARVE: L1 Daily Flight Path Geolocation and Aircraft Position Data, Alaska, 2012-2015
简介
该数据集为 C-23“夏尔巴”运输机在阿拉斯加和加拿大北极地区上空执行空中任务期间提供高频地理定位、时间、高度、俯仰角、滚转角和航向信息,该任务是北极碳储层脆弱性实验(CARVE)的一部分。数据使用机载数字大气数据系统(DADS)现场收集,并在每次飞行中以 1 秒的间隔呈现。飞行任务于 2012 年至 2015 年 3 月至 11 月期间进行,旨在研究大气气体含量的季节性和年际变化。该数据集中包含的测量值可用于将飞机位置与其他 CARVE 机载仪器收集的科学数据进行匹配。
