Abstract. The purpose of the EUNADICS prototype Early Warning System (EWS) is to proceed the combined use of harmonise data products from satellite, ground-based and in situ instruments to produce alerts of airborne hazard (volcanic, dust, smoke and radionuclide clouds), satisfying the requirement of ATM stakeholders (www.eunadics.eu). The alert products developed by EUNADICS EWS (i.e. NRT observations, email notifications and NetCDF Alert data Products, called NCAP) have shown shows the significant interest in using selective detection of natural airborne hazards from polar orbiting satellite. The combination of several sensors inside a single global system demonstrates the advantage of using a triggered approach to obtain selective detection from observations, which cannot initially discriminate the different aerosol types. Satellite products from hyperspectral UV and IR sensors (e.g. TROPOMI, IASI) and broadband geostationary imager (SEVIRI), and retrievals from ground-based networks (e.g. EARLINET, E-PROFILE and the regional network from volcanic observatories), are combined by our system to create tailored alert products (e.g. selective ash detection, SO2 column and plume height, dust cloud and smoke from wildfires). A total of 23 different alert products are implemented, using 1 geostationary and 12 polar orbiting satellite platforms, 3 external existing service, 2 EU and 2 regional ground-based networks. This allows the identification and the traceability of extreme events. EUNADICS EWS has also shown the interest to proceed a future relay of radiological data (gamma dose rate and radionuclides concentrations in ground-level air) in case of nuclear accident, highlighting the capability of operating early warnings with the use of homogenised dataset. For the four types of airborne hazard, EUNADICS EWS has demonstrated its capability to provide NRT alert data products to trigger data assimilation and dispersion modelling providing forecasts, and inverse modelling for source term estimate. All our alert data products (NCAP files) are not publicly disseminated. Access to our alert products is currently restricted to key users (i.e. Volcanic Ash Advisory Centres, National Meteorological Services, World Meteorological Organization, governments, volcanic observatories and research collaborators), as these are considered pre-decisional products. On the other hand, thanks to the SACS/EUNADICS web interface (https://sacs.aeronomie.be), the main part of the satellite observations used by EUNADICS EWS, are shown in NRT, with public email notification of volcanic emission and delivery of tailored images and NCAP files. All the ATM stakeholders (e.g. VAACs, NMSs, WMOs, Airlines and Pilots) can access and benefit of these alert products through this free channel.

EUNADICS预警系统专用于在自然空气传播危害和放射性核素云造成危机的情况下为航空提供支持

摘要。EUNADICS原型预警系统(EWS)的目的是继续结合使用来自卫星,地面和原地仪器的协调数据产品,以产生空中危险(火山,尘埃,烟雾和放射性核素云)的警报,从而满足ATM利益相关者的要求(www.eunadics.eu)。由EUNADICS EWS开发的警报产品(即NRT观测,电子邮件通知和称为NCAP的NetCDF警报数据产品)显示出,人们对使用选择性探测极地轨道卫星产生的自然空气传播的危害表现出极大的兴趣。单个全局系统中多个传感器的组合展示了使用触发方法从观测中获得选择性检测的优势,这些观测最初无法区分不同的气溶胶类型。2个柱和烟羽高度,尘云和野火产生的烟雾)。使用1个对地静止卫星和12个极地轨道卫星平台,3个外部现有服务,2个EU和2个区域性地面网络,共实施了23种不同的警报产品。这样可以识别和跟踪极端事件。EUNADICS EWS也显示出有兴趣在发生核事故的情况下继续进行放射数据(伽马剂量率和地面空气中放射性核素浓度)的中继,突出了使用均质化数据集进行预警的能力。对于四种类型的空气传播危害,EUNADICS EWS展示了提供NRT警报数据产品以触发数据同化和扩散建模(提供预测)以及对源项估算进行逆向建模的能力。我们的所有警报数据产品(NCAP文件)均未公开发布。目前,我们的警报产品仅限于主要用户使用(例如,火山灰咨询中心,国家气象局,世界气象组织,政府,火山观测站和研究合作者),因为这些产品被认为是预先确定的产品。另一方面,借助SACS / EUNADICS Web界面(https://sacs.aeronomie.be),在NRT中显示了EUNADICS EWS使用的卫星观测的主要部分,并通过公共电子邮件通知了火山的排放和提供量身定制的图像和NCAP文件。所有ATM利益相关者(例如VAAC,NMS,WMO,航空公司和飞行员)都可以通过此免费渠道访问并受益于这些警报产品。目前,我们的警报产品仅限于主要用户使用(例如,火山灰咨询中心,国家气象局,世界气象组织,政府,火山观测站和研究合作者),因为这些产品被认为是预先确定的产品。另一方面,借助SACS / EUNADICS Web界面(https://sacs.aeronomie.be),在NRT中显示了EUNADICS EWS使用的卫星观测的主要部分,并通过公共电子邮件通知了火山的排放和提供量身定制的图像和NCAP文件。所有ATM利益相关者(例如VAAC,NMS,WMO,航空公司和飞行员)都可以通过此免费渠道访问并受益于这些警报产品。目前,我们的警报产品仅限于主要用户使用(例如,火山灰咨询中心,国家气象局,世界气象组织,政府,火山观测站和研究合作者),因为这些产品被认为是预先确定的产品。另一方面,借助SACS / EUNADICS Web界面(https://sacs.aeronomie.be),在NRT中显示了EUNADICS EWS使用的卫星观测的主要部分,并通过公共电子邮件通知了火山的排放和提供量身定制的图像和NCAP文件。所有ATM利益相关者(例如VAAC,NMS,WMO,航空公司和飞行员)都可以通过此免费渠道访问并受益于这些警报产品。政府,火山观测站和研究合作伙伴),因为它们被认为是决策前产品。另一方面,借助SACS / EUNADICS Web界面(https://sacs.aeronomie.be),在NRT中显示了EUNADICS EWS使用的卫星观测的主要部分,并通过公共电子邮件通知了火山的排放和提供量身定制的图像和NCAP文件。所有ATM利益相关者(例如VAAC,NMS,WMO,航空公司和飞行员)都可以通过此免费渠道访问并受益于这些警报产品。政府,火山观测站和研究合作伙伴),因为它们被认为是决策前产品。另一方面,借助SACS / EUNADICS Web界面(https://sacs.aeronomie.be),在NRT中显示了EUNADICS EWS使用的卫星观测的主要部分,并通过公共电子邮件通知了火山的排放和提供量身定制的图像和NCAP文件。所有ATM利益相关者(例如VAAC,NMS,WMO,航空公司和飞行员)都可以通过此免费渠道访问并受益于这些警报产品。通过公共电子邮件通知火山喷发以及量身定制的图像和NCAP文件的交付。所有ATM利益相关者(例如VAAC,NMS,WMO,航空公司和飞行员)都可以通过此免费渠道访问并受益于这些警报产品。通过公共电子邮件通知火山喷发以及量身定制的图像和NCAP文件的交付。所有ATM利益相关者(例如VAAC,NMS,WMO,航空公司和飞行员)都可以通过此免费渠道访问并受益于这些警报产品。
