University of Michigan Biological Station Weather Observations 1980 to Present

This data set includes daily year-round weather measurements and observations recorded at the University of Michigan Biological Station (UMBS) from 1980-present. Data primarily serves the purpose of benefitting UMBS researchers needing access to weather data as a confounding variable. Parameters include maximum and minimum temperatures, precipitation, snowfall, snowpack, and estimated cloud cover and type recorded daily at approximately 08:00. Maximum and minimum temperatures were measured at the Biological Station campus with National Weather Service liquid-in-glass thermometers housed in a Weather Service (a.k.a., Cotton Region) shelter located on State Road. Precipitation was measured with either a Belfort Rainfall Transmitter 5915 or an ETI NOAH IV Total Precipitation Gauge in the “UV Field” located immediately northwest of the Biological Station campus. Snowfall and snowpack were also measured in the UV Field on snowboards using National Weather Service according to National Weather Service snow measurement guidelines. Cloud cover was estimated in oktas and classified into one of the ten basic cloud types.本数据集收录了1980年至今于密歇根大学生物站（University of Michigan Biological Station, UMBS）获取的全年每日气象测量与观测数据。本数据集主要用于为密歇根大学生物站的研究者提供可作为混杂变量的气象数据支持。观测参数涵盖每日约08:00记录的最高气温、最低气温、降水量、降雪量、积雪深度，以及估算得到的云量与云型。其中，最高、最低气温的测量采用国家气象局（National Weather Service）的玻璃液体温度计，传感器安置于州道旁的国家气象局气象防护箱（亦称科顿区域防护箱）内，监测点位位于生物站园区内部。降水量的测量使用Belfort Rainfall Transmitter 5915型雨量变送器或ETI NOAH IV型总降水量计，监测点位设置在生物站园区西北侧紧邻的"UV Field"区域。降雪量与积雪深度的测量同样在"UV Field"区域的雪板上开展，测量流程严格遵循国家气象局的积雪观测规范。云量以八分制（oktas）为单位进行估算，云型则被划分为十种基本云型之一。
