摘要
气象资料业务系统MDOS2.0自2016年12月1日正式运行以来,自动气象站(国家级台站除外)海平面气压疑误信息频发,经过对比分析发现,海平面气压疑误信息的根源是观测设备端的气压传感器海拔高度设置有误,与实际海拔高度有很大的差别。通过修正气压传感器的海拔高度后,海平面气压疑误信息不再发生。
Since Meteorological Data Operation System （MDOS） version 2.0 has officially run from December 1 st 2016, the automatic weather station＇s （except national station） sea level pressure suspicious information occurred frequently. Through the comparative analysis, we found that the source of sea level pressure suspicious information comes from difference between the setting of air pressure sensor height and the actual height. By using the sea level pressure calculation formula, substituting the station＇s temperature, pressure, sea - level pressure into the formula, and calculating inversly the station＇s altitude, and correct pressure sensor height. At last, similar sea level pressure suspicious information no longer occurs.
