16 Air Monitoring New weather confi dence platform improves short-term forecast accuracy by up to 50 percent


Vaisala recently announced the launch of the Vaisala Xweather Insight weather confi dence platform at CES 2024 in Las Vegas, United States. Xweather Insight combines Vaisala’s measurement technology and expertise, proprietary Xweather data sets, and novel AI and machine learning into a software and sensors solution to help businesses maximise safety, optimise operations, analyse risk, plan proactively, and make informed decisions—ultimately transforming weather from a challenge into an advantage.


For weather-dependent and weather-sensitive industries, like aviation, renewable energy, utilities, mining, and maritime, Xweather Insight provides the measurements, forecasts, analysis, and alerts needed to optimize daily operations, improve preparedness and resilience against severe weather, and enhance safety, effi ciency, and sustainability.


“Only Vaisala offers the combination of instruments and intelligence to solve businesses’ environmental challenges. With Xweather Insight, we have created a weather confi dence platform that delivers actionable weather intelligence and insights for every business and organization affected by the weather,” says Indrajit Chaudhuri, Chief Platform Offi cer for Vaisala Xweather.


Underpinning the Xweather Insight service is Xcast, a machine learning-based weather prediction technology (MLWP) that enhances short-term forecast accuracy and produces unique actionable insights by using local measurements and observations. Xcast-powered forecasts are up to 50% more accurate than the short-term forecasts generated by traditional numerical weather prediction (NWP) models. What’s more, Xcast also reduces the number of large errors (greater than 2.5 °C) in 24-hour temperature forecasts by up to 59%.


The Xweather Insight platform launches with a set of three modules. With a fl exible subscription model, companies can mix and match modules as needed to meet their business requirements.


The Protect module provides the world’s most accurate severe weather monitoring and alerting solution, giving industries like aviation, energy production, energy transmission, ports, and construction companies the ability to set up thunderstorm warning systems for their locations and keep people and assets safe from lightning. Fully confi gurable for the user, Xweather Protect gives early warnings of approaching storms and notifi es when it is safe to resume work.


For businesses requiring both macro and micro views of the weather and its impact, the Explore module provides an intuitive global map powered by the world’s most accurate forecast and measurement data. It includes more than 40 confi gurable weather and environmental data layers that show real-time weather impacts, as well as a forecast that helps companies take preventative measures against future disruptions.


The Observe module connects the Xweather Insight platform to local sensors. Companies can monitor and analyse real-time observations and historical data, manage devices remotely, and integrate data into business applications and services. The Observe module uses Xcast to produce hyperlocal observation-enhanced forecasts that cannot be achieved with traditional numerical weather prediction (NWP) models.


Xweather Insight is offered as a subscription service that enables companies of any size to confi gure the service to their needs and is available as an API and as a web-based application. Future modules will introduce new capabilities such as alert integration and triggers from the platform into business processes and applications.


“With this launch, Xweather Insight offers a comprehensive set of solutions for protecting and optimizing operations, analyzing risk, planning ahead, and making informed decisions. Weather is complex and ever-changing, but with Xweather Insight, every weather-sensitive industry can turn the weather to their advantage for confi dent operational decision making,” Chaudhuri concludes.

Aero-Laser will be presenting their cutting-edge, AL4021 formaldehyde analyser at the upcoming analytica Exhibition, taking place in Munich this coming April. The AL4021 provides end users with a highly effi cient, continuous, and automated analyser capable of measuring formaldehyde levels down to ppbV for gaseous samples and µg/L for liquid samples. This analyser operates based on a fl uorimetric detection method, which enables it to achieve outstanding selectivity while avoiding interferences with other chemical substances within the sample gas or liquid.


The AL4021 is easy to operate and there is minimal time spent on tiresome, maintenance procedures. This highly sophisticated device is simple to operate via a clear 7” touch screen positioned on the front panel. The AL4021 does all the work, from complete integrated chemical processing, including gas stripping, semi-automated calibration and data storage. This device effi ciently carries out the whole procedure and the operator has more time for other tasks, assured that Aero-Laser’s AL4021 will provide extraordinary levels of precision and great results.


Aero-Laser originally developed the AL4021 for environmental and climate research, it is highly acclaimed in both demanding sectors, and since its launch, it has become widely used for formaldehyde emission monitoring of wood, plastic, or fi bre-based products. The AL4021 has proven to be an invaluable tool for manufacturers needing to conform to the ever-more stringent formaldehyde emission legislation across the globe. Visitors to their stand (A1. 533) will have the opportunity to discuss their specifi c needs with the experts from Aero-Laser, and to see the AL4021 live in action.


Aero-Laser will also present the brand new AL8023 H2 monitor.


Hydrogen plays a key role in the energy supply of a greener future. Therefore a high quality of hydrogen is needed. Impurities can cause serious problems, like damaging the membrane of fuel cells.


The AL8023 allows the online monitoring of organic residues in hydrogen in ppm range. A low need for maintenance, automatic operation, ruggedness and reliability are key features of this unique instrument.


Aero-Laser also offers solutions for monitoring of CO, H2

A global packaging company is monitoring VOC emissions (volatile organic compounds) continuously at its facility in Ireland - primarily to manage and improve the plant’s environmental performance and to demonstrate regulatory compliance. Due to a changeover in equipment, a short-term requirement arose for VOC monitoring with a fl ame ionisation detector (FID) that was hired from Signal Group in the UK.


Feedback from the project indicated that the Signal analyser proved to be accurate and reliable, and provided the packaging manufacturer with a problem-free transition as it updated its monitoring regime. However, there was a delay in the work, and the rental of the Signal analyser was extended for several months.


The plant’s VOC emissions arise from printing and laminating processes, and are treated by an oxidiser, after which an FID analyser measures the total organic hydrocarbon content post-oxidation. By monitoring the emissions continuously, the plant’s operators are able to refi ne their processes to improve effi ciency, and to minimise emissions.


The hired Signal equipment included a heated FID analyser, a heated line with controller, and a fi lter. “We manufacture all of these items, whihc means that the complete system is delivered ready-to-go, so that clients can be assured of compatibility, accuracy and reliability,” explains Signal MD, James Clements. We have hundreds of these systems in operation all over the world, so our staff are highly skilled and experienced in delivering support.


“As the world strives to meet the COP28 goals, manufacturers are looking to reduce their carbon footprint, as well as the carbon footprint of their supply chains. Lowering VOC emissions is one of the ways in which companies can help achieve these critically important objectives.”
