摘要
利用GPS/GLONASS组合精密单点定位(ppp)技术监测近年来北京地区雾霾天气对天顶对流层延迟的影响。研究表明,在雾霾发生时间段,天顶对流层延迟明显上升,天顶对流层延迟的变化趋势与雾霾严重程度整体体现一致性。结合北京雾霾天气特性,单日雾霾变化与天顶对流层延迟变化走势呈一致性。可以利用GPS/GLONASS组合精密单点定位估计的天顶对流层延迟来监测雾霾发生时间段雾霾程度的变化趋势。
Combined GPS / GLONASS PPP method is used to monitor how haze weather affect zenith tropospheric delay in recent years in the Beijing area. Studies have shown that during the haze weather, zenith tropospheric delay increased obviously, the change trend of zenith tropospheric delay is consistent with the change trend of haze weather. Conbined with the characteristics of Beijing ′ s haze weather, daily movements of haze is consistent with changes of zenith tropospheric delay. Using combined GPS /GLONASS PPP method to monior the impact of haze weather on zenith tropospheric delay is possible.
