明年，芬兰的维萨拉传感器及Pegasor颗粒物传感器将被安装于补充空气质量网络中，届时赫尔辛基地区的空气质量测量站点数量将至少增加一倍。新系统将使芬兰首都地区的空气质量信息收集工作变得更加灵活、经济。

“新数据和预测模型将改善首都地区的监测和通信方式。赫尔辛基地区环境服务局（HSY）将在官网和电车及地铁的信息显示屏幕上推出全新的空气质量地图。“我们也计划在为其两年的项目中开始使用预测空气质量的模型，” HSY的空气保护组负责人塔里.克斯肯塔罗如是说。

芬兰气象研究所推出的建模工具ENFUSER将对区域空气质量进行预测，辅助市民规避空气污染物。该模型结合了空气质量数据的气象数据、拓扑图、建筑数据和污染源信息。

空气质量数据和预测模型对空气质量测量措施进行了改良。例如，关于是否需要利用浇水或清洁街道等手段避免有害灰尘污染的预测效果，比以前有很大改观。

该项目的重要部分是开放数据

这是在赫尔辛基都市智慧清洁项目中的一个新型公共主体商业合作模式，为解决城市发展过程中区域内空气污染问题提供解决方案奠定了基础。开放数据是该项目中非常重要的一部分内容，从而使企业不必直接参与项目，就可在此基础上生成解决方案。

“空气质量项目的合作伙伴是该领域在世界上的佼佼者。将他们汇聚在一起，提出的解决方案可以应对世界各地其他城市的不同需求。空气质量数据可用来开发解决方案，从而改善数以百万计人口的生活。我们邀请了所有感兴趣的机构与我们共同开发这些解决方案”，赫尔辛基都市智慧清洁基金会的执行主任蒂娜.卡藿解释说。

“综合性网络能生成比现在我们所能得到的更加详细的空气质量图景。鉴于现在世界各地监测站所用到的我们最新的创新空气质量传感器价格都很低廉，所以创建补充网络不会花费太大成本，”维萨拉公司负责气象业务的执行副总裁雅克.赛兰宁说道。

参与赫尔辛基都市智慧及清洁项目的合作伙伴包括传感器技术提供商维萨拉和Pegasor，负责监测赫尔辛基地区空气质量的赫尔辛基地区环境服务局，项目倡议方、负责预测模型和管理芬兰空气质量检测人员的芬兰气象局，以及负责验证系统的赫尔辛基大学。

空气质量项目是一个例证，表明赫尔辛基都市智慧和清洁基金会可以通过一种全新的合作模式汇集市政、企业、国家机关和研究机构等多方力量，实现多赢的效果。

•世界上首个综合城市空气质量系统将于芬兰的赫尔辛基建成，为当前的测量站提供补充措施。

•更多综合数据可被用来进一步研发空气质量改善措施。

•数据将是开放式的，每个人都可获取，也可用来告知市民当地的空气质量及其发展情况。

•在赫尔辛基都市智慧和清洁项目中汇聚了世界各国在该领域的佼佼者，生成的解决方案可被用于各类正在遭受严重空气质量问题的城市。(本文由中国环保网www.chinaenvironment.com高晶 编译，如需转载，请注明出处）

原文：World’s first comprehensive city-wide air quality system will be built to Helsinki Region in Finland

World’s best experts to build a unique air quality IoT system to Helsinki.

The amount of measurement points will at least double in the Helsinki region as a new supplementary air quality network of Vaisala and Pegasor sensors will be installed during the next year. The new system will enable agile and economical way to gather new information about the air quality of the Finnish capital city region.

"The new data and a predictive model will improve the monitoring and communications in the capital city region. The Helsinki Region Environmental Services Authority HSY will bring new air quality maps to its web site as well as to information screens on trams and the metro. We also plan to start using a predictive air quality model during the two-year project", Head of HSY air protection unit Tarja Koskentalo says.

The ENFUSER modelling tool by the acclaimed Finnish Meteorological Institute will create predictions on the region’s air quality, which will help the citizens to avoid air pollutants. The model combines the air quality data to weather data, topological maps, building data and pollution source information.

The air quality data and predictive model enable air quality improving measures. For example, the need to water or clean the streets to avoid harmful dust can be predicted better than before.

Vital part of the project is open data

A new cooperation model of businesses and public bodies in the Helsinki Metropolitan Smart & Clean project creates the foundation to export the solutions developed in the region to cities, where air quality is a significant problem. Vital part of the project is open data. This enables businesses not directly involved in the project to build solutions based on it.

"The partners in the air quality project have the best know-how on the field in the world. When they come together the solutions created can answer the needs of other cities around the world. The air quality date can be used to develop solutions tha improve the lives of millions of people. We invite all interested parties to develop these solutions with us", Executive Director of Helsinki Metropolitan Smart & Clean Foundation Tiina Kähö explains.

"Comprehensive network will produce a much more detailed picture of the air quality than is possible at the moment. The supplementary network can be built very economically as our new, innovative, air quality sensors cost a fraction of the stations currently used around the world", Vaisala Weather Business Executive Vice President Jarkko Sairanen says.

The partners in the initiative nurtured in the Helsinki Metropolitan Smart & Clean project are the sensor technology providers Vaisala and Pegasor; HSY, who is responsible for the air quality monitoring the Helsinki region; Finnish Meteorological Institute who is the initiative lead as well as responsible for the predictive model and Finland’s air quality official; Helsinki university, who will validate the system.

The air quality project is an example of how the new cooperation model Helsinki Metropolitan Smart & Clean Foundation can bring together the cities, businesses as well as state and research organizations. The cooperation enables everyone to achieve more than they could individually.

•World’s first comprehensive city-wide air quality system will be built to Helsinki Region in Finland. It supplements the current measurement stations.

•The more comprehensive data can be used to further develop air quality improving measures.

•The data will be open and available to everyone and can be used to inform the citizens on about local air quality and its development.

•The cooperation of world leaders in the field in the Helsinki Metropolitan Smart & Clean project enables the solutions to be exported to cities suffering from severe air quality issues.
