Wireless sensor network is important for precision farming to monitor the growth environment of crops in open field, but radio signals are susceptible to different types of interference such as weather and physical objects. This paper designs and implements an environmental monitoring and weather forecast acquisition systems for smart field irrigation based on LoRa(Long Range) and then applies it to a test bed. And we evaluate the network reliability in terms of packet transmission success rate by comparing its condition on two criteria; the existence of obstacle or rain. The results show that much rain falls can affect on packet loss in LoRa field networks with obstacles.

광양지역에 자주 발생하는 해풍에 의한 대기오염물질의 농도분포 특성을 알아보기 위해, 2003년부터 2005년까지 3년간의 기상자료와 대기질 관측자료를 분석하였다. 해풍이 발생한 날은 총 231일 이었으며, 해풍이 발생한 날의 $SO_2$와 $O_3$의 농도는 비해풍일 경우보다 높게 나타나고 있어 광양지역의 대기질의 분포에 해풍의 영향이 중요한 인자임을 알 수 있다.
