VTT Technical Research Centre of Finland is coordinating the 5G-Safe project, which aims to reduce traffic accidents. This involves the development of new vehicular network solutions and the local road weather and safety services they enable in support of drivers, road operators and autonomous vehicle management systems. The new services will require no action from motorists while driving—data will be gathered and warnings will be sent to users automatically. "The wide introduction of real-time services, based on sensor and video data collected from vehicles, is made possible by next-generation 5G mobile network technology and new solutions supporting optimal data collection and exchange," says Tiia Ojanperä, a project manager from VTT. "5G will form the cornerstone of interaction between robot cars, for example. Finnish ICT firms have major export potential in this area. Contemporary driver support systems are mainly vision-based, relying on signals generated by the vehicle's sensors. 5G and short-range radios will also bring the power of speech and hearing to vehicles, taking their capabilities to a new level," states Ojanperä. The services currently being developed require no action during driving in order to send data or warnings. Instead, the prevailing local weather and road conditions are automatically identified based on data collected from vehicles. Warnings and other useful information are sent in real-time to road users, road operators and autonomous vehicle control systems. The new network and cloud computing technologies being researched under the project will reduce delays in data exchange and be more scalable than current services. The 5G-Safe project, which is part of Tekes' Challenge Finland competition, is focused on the identification of local weather and road conditions on the basis of data collected from vehicles, and the sending of warnings to road users. In addition, real-time video and radar data will be exchanged between passing vehicles. Other issues being investigated include the use of data on local road weather conditions to improve the situational awareness of autonomous vehicles and the enhancement of autonomous operation in harsh weather. New business is being sought for the participating companies via this project, which began recently and will end in 2018. The private-sector partners have been actively involved in defining the project's content from the beginning, which improves the prospects of commercialising the results. In addition to VTT, the research partners include Destia, the Finnish Meteorological Institute and its commercial services, Kaltio Technologies Oy, SITO, Tieto and Unikie. Nokia, Sunit and VR Transpoint are participating as sponsors. Support is also being provided by a technical expert group including Bittium, Dynniq (the Netherlands), the Finnish Transport Agency, Telia and the Finnish Transport Safety Agency (Trafi).

Vaisala Press Release May 16, 2017 at 8.00 a.m. Vaisala Measures Air Quality in the First City-Wide System in the World Vaisala instruments will measure the air quality in the Helsinki region in a new measurement network to be built by the Smart & Clean project parties -Vaisala, Finnish Meteorological Institute, Helsinki Region Environmental Services Authority HSY, University of Helsinki, Pegasor, and Helsinki Metropolitan Smart & Clean Foundation - during 2017 and 2018. The network will be the first air quality monitoring system of such accuracy in the world to cover the whole city. The new monitoring network will help compile much more comprehensive information about the air quality in different parts of the Helsinki metropolitan region. The Smart & Clean project aims at improving air quality in the Helsinki region as well as creating new, innovative applications, and piloting solutions suitable for export. Reference measurement stations utilizing traditional methods are very expensive, so their number and regional coverage is highly limited. The measurement instruments launched by Vaisala in the fall of 2016 are based on new technology and can be used to significantly improve local coverage of the measurements at a very reasonable cost. "Actions taken to improve air quality can only be successful when based on measured data which again gives rise to insights. Air quality varies significantly even in very small areas due to e.g. weather, emissions, and traffic flows, so we need local information to improve people's quality of life and to achieve a deep understanding of metropolitan air quality," says Jarkko Sairanen, Vaisala EVP for the Weather Business Area. Air quality is a growing health problem around the world. More than 80% of people living in urban areas are exposed to air pollution levels that exceed WHO limits. According to WHO estimates, approximately 7 million people died prematurely because of air pollution in 2012. While all regions of the world are affected, populations in low-income and densely populated cities are the most impacted. Major cities in Europe, such as Paris or London, also suffer from this problem. In Finland, air quality is generally good, but even here 40% of city dwellers get symptoms from street dust, and air pollution is estimated to cause about 1,600 premature deaths per year. The increase in health problems and premature deaths have a direct impact on the economy through higher medical expenses and loss of productivity. The new air quality monitoring system uses Vaisala's innovative AQT400 series transmitters. They are a low-cost solution to measuring reliably the most important air pollutants: particles, nitrogen dioxide, sulfur dioxide, ozone and carbon monoxide. The instruments are easy to install and deploy as well as to maintain. They can also be connected to Vaisala's weather measurement equipment as well as different air quality modeling systems. The combination can significantly improve the reliability of real-time air quality measurements in diverse terrain and city environments. The project uses the latest technology and cutting-edge air quality knowhow from Finland. Vaisala Vaisala is a global leader in environmental and industrial measurement. Building on 80 years of experience, Vaisala contributes to a better quality of life by providing a comprehensive range of innovative observation and measurement products and services for chosen weather-related and industrial markets. Headquartered in Finland, Vaisala employs approximately 1,600 professionals worldwide and is listed on the NASDAQ OMX Helsinki stock exchange. www.vaisala.fi

The areal extent, concentration and thickness of sea ice in the Arctic Ocean and adjacent seas have strongly decreased during the recent decades, but cold, snow-rich winters have been common over mid-latitude land areas since 2005. A review is presented on studies addressing the local and remote effects of the sea ice decline on weather and climate. It is evident that the reduction in sea ice cover has increased the heat flux from the ocean to atmosphere in autumn and early winter. This has locally increased air temperature, moisture, and cloud cover and reduced the static stability in the lower troposphere. Several studies based on observations, atmospheric reanalyses, and model experiments suggest that the sea ice decline, together with increased snow cover in Eurasia, favours circulation patterns resembling the negative phase of the North Atlantic Oscillation and Arctic Oscillation. The suggested large-scale pressure patterns include a high over Eurasia, which favours cold winters in Europe and northeastern Eurasia. A high over the western and a low over the eastern North America have also been suggested, favouring advection of Arctic air masses to North America. Mid-latitude winter weather is, however, affected by several other factors, which generate a large inter-annual variability and often mask the effects of sea ice decline. In addition, the small sample of years with a large sea ice loss makes it difficult to distinguish the effects directly attributable to sea ice conditions. Several studies suggest that, with advancing global warming, cold winters in mid-latitude continents will no longer be common during the second half of the twenty-first century. Recent studies have also suggested causal links between the sea ice decline and summer precipitation in Europe, the Mediterranean, and East Asia. © 2014, The Author(s).

The PyTMatrix package was designed with the objective of providing a simple, extensible interface to T-Matrix electromagnetic scattering calculations performed using an extensively validated numerical core. The interface, implemented in the Python programming language, facilitates automation of the calculations and further analysis of the results through direct integration of both the inputs and the outputs of the calculations to numerical analysis software. This article describes the architecture and design of the package, illustrating how the concepts in the physics of electromagnetic scattering are mapped into data and code models in the computer software. The resulting capabilities and their consequences for the usability and performance of the package are explored.©2014 Optical Society of America.
