LTER Meteorological Stations at the Kellogg Biological Station, Hickory Corners, MI (1988 to 2020)

Meteorological data have been collected on the LTER main site since 1988. Originally, wind direction and speed, total solar radiation, net solar radiation, rainfall, air temperature, and relative humidity were recorded hourly in connection with measurements of evapotranspiration and deep percolation from a 6 m2 in-ground weighing lysimeter. The lysimeter and fetch area were planted to continuous alfalfa. Although the lysimeter is no longer in operation, weather data collection continues. Precipitation was measured with a tipping bucket rain gauge until fall of 1997, when it was replaced with a weighing bucket rain gauge. In 2007 the belford rain gauge was replaced by a NOAH IV weighing bucket gage. All other sensors are electronic, connected to a data logger that is polled remotely. Instruments to measure wind speed and direction are mounted on a tower at 10 m. Light sensors (net solar radiation and photosynthetically active radiation) a thermometer, and an RH probe (with a built-in thermometer) are mounted at about 3 m. Soil moisture and temperature are monitored near the base of the tower.

自1988年起，在LTER主要研究站开展了气象数据的收集工作。起初，与蒸发蒸腾量和深层渗透率测量相结合，每小时记录风向、风速、总太阳辐射、净太阳辐射、降雨量、空气温度和相对湿度。6平方米的地下称重蒸散仪被用于这些测量。蒸散仪及其取用区域种植了连续的紫花苜蓿。尽管蒸散仪现已停止运行，但气象数据的收集工作仍在继续。直至1997年秋季，降水量使用倾倒式雨量计进行测量，随后被称重式雨量计所替代。2007年，贝尔福德雨量计被NOAH IV称重式雨量计所替换。所有其他传感器均为电子式，并连接至远程轮询的数据记录器。测量风速和风向的仪器安装在10米高的塔架上。光传感器（净太阳辐射和光合有效辐射）、温度计以及内置温度计的相对湿度探头（RH探头）均安装在大约3米的位置。土壤湿度和温度在塔架底部附近进行监测。
