2 200/2017 President’s Column Doing Good is Good Business

At Vaisala we are very fortunate to work for a company that really makes a difference in the world. At best, we can say without any hesitation that we help save lives. Our work is also instrumental in improving people’s living and working conditions, ensuring products are manufactured as efficiently and safely as possible, resulting in dependable and high-quality products, and saving energy or producing energy more efficiently. In short, we try to be net positive: in our vision that means doing business in a way which puts back more into society, the environment, and the global economy than it takes out – having a bigger handprint than footprint. The impact can be seen in many articles in this magazine. Improv- ing water reservoir management is essential in drought-riddled California, lightning data helps decrease fatalities and injuries caused by lightning in U.S. agriculture, and a new observation network in the Helsinki area in Finland will monitor air quality and hence provide information essential for assessing the environment. Being net positive is in no way in contrast with doing business, quite The idea of improving the world the opposite.

Global Dataset Available for Research

Vaisala was also the first to map the world’s solar energy resource potential through a high-resolution dataset that continues to be used today by developers, project owners, policymakers and governments to make high-level financial, infrastructure and operational decisions. Recently Vaisala partnered with IRENA, the International Renewable Energy Agency, to make portions of this dataset publicly available through its Global Atlas platform. The aim is to increase access to high-

200/2017 7 Using Lightning Education and Data to Reduce Injuries and Fatalities in Agriculture

The agriculture industry shares an obvious connection with weather – rain helps irrigate crops, severe storms can damage crops, and temperatures can be helpful for growth or too extreme. Agriculture workers experience all types of weather, including thunderstorms and lightning. Because of the outdoor work environment, their exposure to lightning is higher and this increases their risk of injury or death. In addition, they are more at risk because of their proximity to a safe shelter. If we consider the United States alone, according to the National Weather Service, 34% of work-related lightning fatalities are associated to farming or ranching. Outside of the United States, there have been 445 events recorded since 1993, where information about thunderstorms. lighting injuries and fatalities. Many injury or death of an agricultural Information such as, what types of times workers do move to safety worker occurred because of light- clouds produce thunderstorms and during storms; however, sometimes ning.

Lightning Data

Finally, one of the most effective ways to protect against lightning strikes in agriculture is to be ahead of the storm and invest in an alerting system. Farmers are typically aware of approaching storms, but having the ability to know how close storms are, or which way they are moving can also help reduce the risk of the threat of lightning. Technology, such as Vaisala’s Thunderstorm Manager tracking and alert system, allows workers to monitor conditions, and make decisions about if or when workers should leave their positions, and move to safety. Thunderstorm Manager uses lightning data from time, and reduce their risk of being implement an educational program, Vaisala’s global lightning network, injured or killed by lightning. build or provide safe structures, and the GLD360 Global Lightning Dataset.

Observations were taken at regular intervals, based on weather forecasts and model data – every three hours during storm events, and more frequently during peak times, which may last anywhere from 10 hours to 100 hours. Wilson shared that collecting observations was exciting and sometimes stressful because lead times were often short. “Quick deployment was key to successful data collection, so the portability of the RS-41 was a definite benefit. Also, it was great to be able to see the radiosonde data in real-time, which

The net output of its two nuclear plant units currently in operation is 880 megawatts. Together, these units produce one sixth of all the electricity consumed in Finland.

For its own electricity needs, the utility has high-voltage transformers for stepping down the energy from a 400 or 110 kV network. One of these is a stand-by transformer, which turns on automatically, if any of the other transformers suddenly stop operating.

Installation in Two Hours Vaisala has recently launched its new Optimus DGA Monitor for Transformers. As a result of its careful design and the patented technology, the monitor measures reliably without giving any false alarms.

This is possible, firstly, because the monitor carries an IR sensor based on Vaisala core measurement technology and components manufactured in the Vaisala in-house cleanroom. Secondly, the monitor uses vacuum gas extraction, which gives a fully representative sample and means no data fluctuation due to oil temperature, pressure, or type.

The monitor stays reliable over time, as hermetically sealed and protected optics prevent sensor contamination, and long-term drift is eliminated with an unique autocalibration functionality.

The Vaisala Optimus™ DGA Monitor is designed to be installed in less than two hours – the users need only to connect the oil, power, and data connections. The user interface is browser-based, and no additional software is needed.

Traditionally, air quality is measured using reference measurement stations that are very expensive, so their number and regional coverage is highly limited. The network uses Vaisala instruments, launched in the fall of 2016, that can be used to significantly improve local coverage of the measurements at a very reasonable cost. The AQT400-series transmitters are a low-cost solution to measuring reliably the most important air pol- lutants: 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.

It can measure not only the hydrogen peroxide content (ppm) of bio-decontamination but also temperature, relative humidity (RH, only water vapor), and relative saturation (RS, whole gas mixture). “The repeatability of measurements is extremely important to achieve reliable verification of the bio-decontamination process cycle after cycle,” says Vaisala Product Manager Sanna Lehtinen. The main factors in the probe’s repeatability are its new PEROXCAP® sensor, intelligent algorithm, and heating function.
