摘要

大气中二氧化硫是火山活动的重要指标。MetOp上的GOME-2和EOS-Aura上的OMI等空间大气传感器使探测火山二氧化硫排放和监测全球范围内的火山活动和喷发成为可能。利用GOME-2,可以近实时地探测和跟踪火山喷发羽流和被动脱气产生的二氧化硫。这对早期预警服务尤其重要,因为二氧化硫通量的增加是火山动荡新发作的一个指标。来自太空的二氧化硫每日测量用于与火山风险相关的几个预警服务(Exupery, GlobVolcano)和航空预警目的(GSE-PROMOTE)。

Monitoring of volcanic SO2 emissions using the GOME-2 satellite instrument
Atmospheric sulfur dioxide is an important indicator of volcanic activity. Space based atmospheric sensors like GOME-2 on MetOp and OMI on EOS-Aura make it possible to detect the emissions of volcanic SO2 and monitor volcanic activity and eruptions on a global scale. With GOME-2, it is possible to detect and track volcanic eruption plumes and SO2 from passive degassing in near-real time (NRT). This is particularly important for early warning services, as increases in SO2 fluxes are an indicator for new episodes of volcanic unrest. The SO2 daily measurements from space are used for several early warning services related volcanic risk (Exupery, GlobVolcano) and for aviation warning purposes (GSE-PROMOTE).
