摘要
以漠河县2010年3种日照仪器对比观测数据为基础,使用阈值为120w/m2的直接日射表作为日照基准仪器进行分析,得出的结论为:在高纬度地区(纬度大于40°)暗筒式日照计记录相对偏少,聚焦式日照计更加接近真实日照时数。
Mohe County in 2010 compared three kinds of sunshine instrument based on observational data, using a thresh- old value of 120 w/m^2 direct sunlight insolation table as reference instruments for analysis. The conclusions were found that at high latitudes （ latitudes greater than 40 degrees） Sunshine hours was recorded few relatively by dark Cartridge sunshine, it was closer to reality focusing style sunshine.
