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: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
