Despite great efforts by governments worldwide, particulate pollution in the cities is growing. While car-free zones in Europe are supposed to minimize pollution and avoid traffic jams, more than ten million new cars a year in China have the opposite effect. Although the Chinese government is also trying to fight the inevitable stop-and-go traffic in cities such as Beijing or Shanghai, the growing prosperity creates an increasing demand for cars.

Learning from mistakes

The result of an uncontrolled traffic concept could be seen in the capitals of the Four Asian Tigers or Thailand. Centers like Bangkok were suffering from severe air pollution during the booming years of the 1990′s. It was nearly impossible to leave the house without a breathing aid or protection. Grey clouds of fine dust were covering the city like a cheese bell. It made breathing a torment and showed that, next to the positive effects of growing prosperity, this was a very harmful side effect.

The cosy fire, the poor air

But not only cars and trucks pollute the environment with fine dust particles. Danger also comes from a very cosy heat source: the fireplace. While one has made oneself comfortable in front of the fire, smallest pieces of particulate matter fly up the chimney and pollute the air we breathe. Particulate matter and other harmful substances are released from incomplete combustion – especially when too little oxygen for the combustion process is available. Even newer furnaces do not necessarily guarantee enough oxygen for a fluent buoyancy.

LUFFT measures what is invisible to the naked eye

The first step in improving the air quality is to identify the damage and the source of damage accurately. So what is the impact of particulate matter and where do they come from? Lufft thus has developed the compact weather station WS600-UMB. This is used by the Federal Environment Agency to measure lengths of ultra-fine dust. In the town of Langen near Frankfurt different metrics of particulate matter (number, number of surface particle size spectra) were examined and assigned to different groups. The distribution of particle sizes provides important clues to the sources of ultra-fine particles. Therefore Lufft actively helps to find ways to improve air quality.

There is no bad weather, there’s only inappropriate clothing. So says the North German, meaning that you can enjoy all kinds of weather, provided you are properly dressed.

Die Sonne hat für den Menschen seit jeher eine herausragende Bedeutung. Einmal davon abgesehen, dass die Sonne für die Photosynthese und damit für das Leben auf dem Planeten Erde im Ganzen eine herausragende Rolle spielt, wurde sie schon früh von den Menschen als Grundlage für Bemessungen genutzt.

Die Sonne hat für den Menschen seit jeher eine herausragende Bedeutung. Einmal davon abgesehen, dass die Sonne für die Photosynthese und damit für das Leben auf dem Planeten Erde im Ganzen eine herausragende Rolle spielt, wurde sie schon früh von den Menschen als Grundlage für Bemessungen genutzt.

Bereits 2500 v. Chr. tauchten die ersten Sonnenuhren in China auf. Dabei handelte es sich im Grunde nur um Stäbe, die senkrecht in den Boden gesteckt wurden und deren Schattenlänge grobe Rückschlüsse auf die Zeit zuließ. Knapp zweitausend Jahre später erreichten diese frühen Sonnenuhren dann Griechenland. Der „Schattenstab“ wurde dort Gnomon genannt, was übersetzt „Erkenner der Zeit“ bedeutet. Die Gnomonik steht im Übrigen noch heute für die Lehre von den Sonnenuhren.

Die Zeit in „Füßen“ messen

Die erste mobile Uhr war der eigene Körper. Man nutze den selbsterzeugten Schattenwurf, um die Zeit zu ermitteln. Die Länge des eigenen Schattens wurde mit den Füßen gemessen. Zur Bemessung der Zeit wurden dann sogenannte Stundentafeln herangezogen, die auf einer Körperlänge von sieben Fuß basierten. Zum Essen wurde man also auf eine bestimmte Fußlänge eingeladen. Abhängig davon, wie groß die Füße des Messenden waren, konnte die Zeit allerdings deutlich variieren. Dennoch, diese „Genauigkeit“ reichte damals vollkommen aus.

Die ersten „genauen“ Sonnenuhren

Im Mittelalter setzten sich in Europa die Gebetsuhren durch. Geistliche in Kirchen und Klöstern brauchten für den geregelten Gang ihrer Offizien ein Zeitmaß. Hierbei spielte die genaue Uhrzeit keine Rolle, dafür aber die Gleichmäßigkeit der Zeitabschnitte. Einen großen Schritt machte die Sonnenuhr zur Zeit der Renaissance. Man begann den Schattenwerfer parallel zur Erdachse in Richtung des Himmelspols auszurichten. Dieser sogenannte Polstab bildete mit der Horizontebene des Aufstellungsortes einen Winkel, der der geografischen Breite entsprach. Das besondere daran: Nun hing die Zeitanzeige nur von der Richtung des Schattens ab und wurde nicht mehr durch die jahreszeitlich veränderliche Höhe der Sonne beeinflusst. So konnte man fortan eine Zeitskala verwenden, die das ganze Jahr über galt.

Die Intensität der Sonne

Heute nutzen wir Sonnenuhren nur noch als dekorative Accessoires in repräsentativen Räumen oder Gärten. Aber immer noch messen wir die Sonne. Doch weit wichtiger als der bloße Verlauf ist die Intensität ihrer Strahlung. Dies gilt insbesondere für Photovoltaikanlagen, die entweder von Privatpersonen auf Dächern von Wohnhäusern oder landwirtschaftlichen Gebäuden aufgestellt werden, oder aber in Form von Solarkraftwerken überall entstehen. Denn auch, wenn die Sonne immer da ist, so ist ihre Strahlung nicht immer gleich intensiv und nicht jeder Winkel auf unserem Planeten profitiert gleichermaßen stark von ihrer Strahlkraft.

Die Sonne als Kraftwerk

Wer gerade eine Photovoltaikanlage plant, ist gut beraten, im Vorfeld zu prüfen, ob der geplante Standort auch geeignet ist, um dort die gewünschte Menge Strom zu erzeugen. Ist die Anlage installiert, muss zudem sichergestellt werden, dass sie extremen Wetterbedingungen standhalten kann. Lufft kann hier Planer und Betreiber von Solaranlagen mit entsprechenden Messinstrumenten unterstützen. Umweltsensorik hilft die Panels im Betrieb zu schützen. So werden diese bei der Gefahr von Stürmen flachgelegt, oder mittels Trackern jeweils der Sonne nach ausgerichtet. Das Gute dabei: Lufft Messgeräte sind um ein Vielfaches genauer, als es die besten Sonnenuhren je waren.

Wind turbines are growing up. Environmental conditions for new locations are becoming more and more extreme, colder, and more salt-ridden due to offshore placement. At the same time, the turbines are getting bigger and bigger. This means that they need better reliability over longer periods of use. It takes 8-10 years to amortize the cost of the turbines, followed by several years of operation for the investment to turn profits.

More than almost any other outdoor sport, ski jumping and ski flying are determined by the weather. It is not just that the wind conditions have a decisive influence on the results of jumping competitions. It already starts weeks before the event as the hills are being prepared. Nowadays, snow cannons can make up for lacking snowfall, but these too require certain weather conditions for optimal operation—mostly at night and outside of business hours.

You are not in the mood for grey weather anymore? You are fed up with snow, sleet and roads slippery with black ice? You still have some leftover leave from last year? Lucky you! You could take the next flight to someplace nice and warm. Where the sea sparkles in the sunlight in shades of blue, where you walk barefoot in the warm sand and enjoy colourful sunsets and mild evenings at the hotel bar. At least, that is how it should be. If luck turns bad on you, the winter weather might be following you and your spontaneous trip might be drowned in thunderstorms and rain. That would be a shame, but still not a matter of life and death. Of course.
