Long Term Tree Growth Sites: Hourly Temperature and Hourly Relative Humidity at 150 cm from 1988 to Present

Data logger instrumentation was installed at several of the of the Long Term Tree Growth (LTTG) study sites to monitor air temperature and relative humidity in various forest types.研究团队在多个长期树木生长（Long Term Tree Growth, LTTG）研究样地中布设了数据记录仪（data logger）监测设备，用以监测不同林型下的空气温度与相对湿度。
