格尔木站陆上蒸发场迁移前后资料一致性分析

Analysis of data consistency before and after relocation of Germu evaporation field

2003年7月前,格尔木站陆上水面蒸发观测场设在测站院墙外,为宽阔平坦无遮挡的戈壁滩;2003年8月因测站设施改造,将观测场由院外迁至院内。受遮挡率、风力等因素的影响,迁移后的院内观测资料与历年资料对比成果偏小,为使资料与历年资料保持一致性,具有代表性和可靠性,对该站蒸发观测场迁移时的平行观测资料进行对比分析。

Before July 2003, the evaporation observation field of Germu station is located on fiat stone desert without any shelter. In August 2003, the observation field was relocated into the station yard due to reconstruction of the station facilities. After relocation, affected by screening rate and wind force, the observation data obtained in the yard are less compared to the data over the years. Therefore, the parallel observation data during relocation of the evaporation observation field are compared and analyzed so as to keep them consistent with the data over the years, and be representative and reliable.
