Dutch satellite images of air quality visible in Google Earth

17.10.2007
Everyone can now follow the emission and spread of atmospheric pollutants and greenhouse gasses using Google Earth. SRON Netherlands Institute for Space Research and the Netherlands Meteorological Institute KNMI have made available the images from the space instruments SCIAMACHY and the Ozone Monitoring Instrument OMI via Internet.

Using Google Earth these images can be projected onto the globe and shown as short films. For example, according to Ilse Aben, head of atmospheric research at SRON, everyone can now see the relationship between the emission of methane and rice fields at a single glance.

The current interest in climate change amongst the press, the general public and politicians is greater than ever before. Google Earth enables interested parties, but also scientists, to quickly and simply gain an initial idea of what is happening in the atmosphere. Within just a few days satellites can gain an impression of the composition of the atmosphere over the entire world. They consequently play a vital role in research into the atmosphere and climate.

While the signs for climate change are unmistakable, the complexity of the climate system is also becoming increasingly apparent. Climate researchers are continuously searching for associations between different data sets, says Ilse Aben. For example, with the help of Google Earth, the SCIAMACHY measurements of the air pollutant carbon monoxide and the greenhouse gas methane can now be easily correlated with forest fires and rice fields. According to Pieternel Levelt of the KNMI, principal investigator of OMI, Google Earth is also highly suitable for the presentation of the intricate measurements of OMI. Now we can see which cities or valleys are hot spots for nitrogen dioxide. It turns out that large volumes of pollutants continue to hang above the Po plain in Italy. Nitrogen dioxide is an air pollutant but also plays a role in the formation of greenhouse gasses. The big advantage of Google Earth is that everyone can now access the information in an easy to use manner and compare different types of information with just a single mouse click.

Geography lesson
In future, an increasing number of images from Earth observation satellites will be used in Google Earth. Apart from being useful for scientists, it also opens up options for many educational applications, in geography lessons for example.

With the space instruments SCIAMACHY, on the ESA satellite Envisat, and OMI, on the NASA satellite EOS-AURA, the Netherlands plays a leading role in atmospheric space research. KNMI and SRON are currently working with the Dutch space industry on the preparations for a new space instrument, TROPOMI, which will combine the best of SCIAMACHY and OMI.

SCIAMACHY data for use in Google Earth are prepared for SRON by Matthijs Krijger. They can be downloaded from: http://www.sron.nl/google_earth.

OMI data for use in Google Earth can be downloaded from: http://www.temis.nl.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
