Wind fields from WRF can now be used directly in the Airviro integration of the US/EPA CALPUFF model by using the CALPUFF ready format. This makes it possible to simulate Air Quality with CALPUFF in Airviro without having access to meteorological measurements. It also makes dispersion modelling in Airviro with CALPUFF available for larger scales.

Apertum has developed and integrated a large number of protocols in the Campbell data logger that enables communication with Air Quality instruments. These protocols in the Campbell data logger are configurable from a user interface in the Airviro system. This makes it possible to use Campbell data loggers in Air Quality stations.

In cooperation with Winsys Technology, the current Airviro system at Meteorological Services Singapore (MSS) will be replaced by another enhanced Airviro system. The system will collect data from the current meteorological network that will be extended.

Airviro v6.00 has been released. With a completely new graphical design of the user interface, it will improve the user experience and make better use of the available screen size. The rollout to customers has already started.

In cooperation with Elite Technology and Environment, an Airviro system has been installed for the Ministry of Environment and Climate Change (MECC) in Qatar. The system will collect data from Air Quality Monitoring stations all over Qatar.

In cooperation with Winsys Technology, an Airviro system has been installed for the Ministry of Defense in Singapore. The system will collect data from meteorological stations in Singapore.

Due to an increased awareness of IT security threats, there is an ongoing work to improve the security in Airviro and we will release a government security edition of Airviro in mid 2023 (with version 6.00). The edition will include:

• The possibility to deploy in a 3-tier architecture setup: A web tier, an application tier and a database tier.
• Main & Reserve system combined with 3-tier architecture setup, i.e. on six servers instead of two, for high security and availability.
• Encrypted data in the database tier, which means that all data stored in the database as well as the transport to/from the application layer is encrypted at all times.
• Improved authentication and session handling in Airviro to minimize the risk of intrusion.
• The data collection module in Airviro is built using plug-ins for communicating with various instruments and loggers and enables developments of protocols with channel/link encryption. Examples of such protocols are HTTPS, MQTT and OPC UA.
• Deployment of Airviro in a cloud environment such as Azure, AWS, or GCP is possible and already used by some of our customers.

The work with the next major version of Airviro is in full progress. The main features will be a new framework that makes better use of the users screen, a new graphical design and it will be completely HTML-frameless. This new version is expected to be released in the beginning of 2023.

Airviro v5.10 has been released. This release will be the last in the v5.x series and is more of a consolidated version with focus on security improvements and the removal of HTML-frames from the application. It also contains a new Heatmap graph and a function to see more information about dispersion results.

Due to an increased awareness of IT security threats, there is an ongoing work to improve the security in Airviro and we expect to release a government security edition of Airviro during 2022. The edition will include:

• Deployment of Airviro in a 3-tier architecture setup: A web tier, an application tier and a database tier.
• Main & Reserve system combined with 3-tier architecture setup, i.e. on six servers instead of two, for high security and availability.
• Encrypted data in the database tier, which means that all data stored in the database as well as the transport to/from the application layer is encrypted at all times.
• Improved authentication mechanism in Airviro to minimize the risk of intrusion.
• The data collection module in Airviro enables developments of protocols with channel encryption. Examples of such protocols are HTTPS and OPC UA.
• Deployment of Airviro in a cloud environment such as Azure, AWS, or GCP is possible and already used by some of our customers.

Apertum and The National Institute of Metrology in China, NIM, are developing an Urban Receptor system. The aim is to detect unknown emission sources that are not included in the emission database. The system is run in real time and will also be used to detect transient emission sources.

We can now offer a new or updated physiography and topography data set to a low cost by using public sources on the web. Please contact us for more information.

Apertum will deliver a full Airviro system to Belhydromet in Minsk, Belarus. The project “ENI/20I9/407-833 Modernisation of Air Quality and Radiation Monitoring Infrastructure” is financed by EU under the EuropeAid program.

Airviro v5.01 has been released. The most important news are better user interface for Dispersion, improved import functionality for EDB sources and re-designed handling of dispersion simulations. This version v5.01 will be followed by v5.02 with even more functionality. When upgrading to v5.01, v5.02 will be free of charge.

APERTUM is participating in a EU Horizon 2020 project (CLARA) that is aimed at making innovations by using climate services. The CLARA project received funding from the European Unions Horizon 2020 programme (GRANT AGREEMENT No 730482). A meeting for all participants has been held in Norrköping the 24:th of June to the 26:th.

Airviro v5.0 is now released. The most important new functionality in Airviro is the possibility to use Open Street Map (OSM) as an internet source for maps. The NORTRIP re-suspension emission model has also been integrated into the Airviro EDB. v5.00 will be followed by v5.01 with more new functionality. When upgrading to v5.00, v5.01 is free of charge.

Apertum and EERC in collaboration with Birmingham City Council invites you to the 2019 Airviro UK user group meeting. Share experiences with other Airviro users, get the latest news on Airviro 5.00, get your questions answered and give us your input on further developments of Airviro. Please contact info@apertum.se if you are interested in participating.

The Chinese National Institute of Metrology has bought an Airviro system aimed at making air quality simulations around industrial sites in the China. They will use the Receptor model to locate dominating sources and estimate the emissions from the sources as well as making Gaussian dispersion calculations.

The UK National Physical Laboratory has bought an Airviro system aimed at making air quality simulations around industrial sites in the UK. They will also use the Receptor model to locate dominating sources and estimate the emissions from the sources.

We are happy to announce that the Excel plug-ins Waved and Wedbed are now available for 64-bit MS Office. You can download them from:

APERTUM is participating in a EU Horizon 2020 project that is aimed at making innovations by using climate services. The project has been ongoing for one and a half year now and the second Multi-User Forum was held in Cordoba, Spain 13-14 Nov. The purpose of this workshop was to get feedback from a group of potential users to the services developed under this project.

The Java applet-free version v4.01 of Airviro has now been released. This means that all Java applets has been replaced with more modern solutions.

APERTUM and EERC in collaboration with Leicester City Council held the 2018 Airviro UK user group meeting on May 10 in Leicester. The upcoming Airviro version v4.01 that is Java-applet free was demonstrated and there were also discussions about emission databases. Erik Teinemaa representing the new Airviro partner EERC gave a presentation about EERC.

The Airviro System has up to now been owned in equal shares between the Swedish Meteorological and Hydrological Institute (SMHI) and Apertum IT AB. SMHI have now decided to transfer it's half of the ownership to the Estonian Environmental Research Centre (EERC, Eesti Keskkonnauuringute Keskus OU).
