Application Research of Meteorological Observation system for analyze relationships between terrestrial vegetation and atmosphere

为了在热带偏远地区进行长期的气象观测，同时进行感热和潜热通量的观测，对自动气象站系统进行了比较。自动气象站的通量观测系统已有商业化供应，但这些系统往往会使数据缺乏周期，特别是在高湿度条件下运行在热带地区。应用一传感器一数据记录仪系统对泰国北部丘陵常绿森林进行了连续观测。对于偏远地区的长期观测，建议采用并联系统。本文给出了利用并行系统连续观测的气象资料的几个结果，如“局部季风气候下森林坡面夜间排水流量的季节变化趋势”，以及该系统两年的气象要素记录。

In order to conduct a long-term meteorological observation together with sensible and latent heat flux in remote area in tropical region, automatic weather station systems are compared. Automatic weather station systems with flux observation have been commercially supplied, these systems often made data lacking period especially operated in tropical region because of high moisture condition. One sensor by one data logger system for meteorological measurement is applied to continuous observation in hill evergreen forest in northern Thailand. Parallel system is recommended for long term observation in remote site. Several result using continuous observed meteorological data by parallel system is presented in this report, such as "Seasonal trend in the occurrence of nocturnal drainage flow on a forested slope under a topical monsoon climate" together with two years records of meteorological factors by this system.
