Global Summary of Day (GSOD) from the National Climatic Data Center (NCDC)

The daily observation data are the gauge data from the Global Summary of Day (GSOD) from the National Climatic Data Center (NCDC). This dataset includes daily mean visibility (VIS), sea level pressure (SLP), temperature (TEMP), dew-point temperature (DEWP), wind speed (WS) and other meteorological phenomena as well as fog, rain or drizzle, snow or ice pellets, hail and other extreme weather.

本数据集所用的逐日观测数据，为美国国家气候数据中心（National Climatic Data Center, NCDC）全球每日摘要（Global Summary of Day, GSOD）中的地面实测资料。该数据集包含日平均能见度（daily mean visibility, VIS）、海平面气压（sea level pressure, SLP）、气温（temperature, TEMP）、露点温度（dew-point temperature, DEWP）、风速（wind speed, WS）等多种气象要素，同时涵盖雾、雨或毛毛雨、雪或冰丸、冰雹等极端天气现象的相关记录。
