FASTEX soundings from Narssarssuaq. Version 1.0

This dataset consists of sounding data from Narssarssuaq in Greenland (WMO 04270) which was operated by the Danish Meteorological Institute. Soundings were taken four times per day (00, 06, 12, and 18 UTC) except during selected IOPs when it was up to eight times per day (also 03, 09, 15, and 21 UTC). These data were processed through automated and visual quality control. This dataset includes pressure, temperature, dew point, relative humidity, wind speed, wind direction, and altitude taken at 10 second vertical intervals. Refer to the station README for details.

本数据集包含格陵兰岛纳尔萨克（Narssarssuaq）站点（世界气象组织编号 WMO 04270）的探空数据，该站点由丹麦气象研究所（Danish Meteorological Institute）运营。探空观测通常每日进行4次（协调世界时 UTC 00:00、06:00、12:00、18:00），但在选定的强化观测期（Intensive Observation Period, IOPs）内，观测频次可提升至每日8次（新增 UTC 03:00、09:00、15:00、21:00）。所有数据均经过自动化与人工目视双重质量控制处理。数据集涵盖的变量包括气压、气温、露点温度、相对湿度、风速、风向及海拔高度，观测数据以10秒的垂直时间间隔采集。详细信息请查阅该站点的README文件。
