Taking the pulse of Earth’s ecosystems

Taking the pulse of Earth’s ecosystems

Susan Steele-Dunne has been awarded a NWO Vici grant. She will explore how to monitor the pulse of the Earth’s ecosystems using radar observations. Variations in radar observations from a forest during a day can reveal early warning signs of declining health conditions of a forest. An improved understanding of these processes will allow us to make better predictions of how ecosystems will respond to respond to climate change. In the long term, it may even offer opportunities for early interventions.

Clouds disappear quickly during solar eclipse

Clouds disappear quickly during solar eclipse

Cumulus clouds over land start to disappear almost instantly during a partial solar eclipse. Until recently, satellite measurements during the eclipse resulted in dark spots in the cloud map, but researchers from TU Delft and KNMI were able to recover the satellite measurements by using a new method. The results may have implications for proposed climate engineering ideas, because disappearing clouds can partly oppose the cooling effect of artificial solar eclipses. The results were published today in Nature Communications Earth and Environment.

Unique permanent coastal observation detects minimal changes

Unique permanent coastal observation detects minimal changes

A team of researchers from TU Delft has succeeded in long-term mapping of beach topography to within a few centimetres. The unique dataset provides insights into coastal changes for every hour, for three years. This data is important for dune maintenance and to keep the hinterland well protected. The methodology is also being used to monitor other coastlines and even glaciers. The data are open source and published in Nature, and the new methodology was also recently published.

Ruisdael Observatory maps atmosphere of the Netherlands

Ruisdael Observatory maps atmosphere of the Netherlands

What was just a dream five years ago is now starting to become reality. Thanks to hundreds of sensors and several measurement towers, the Ruisdael Observatory continuously provides a clear picture of the atmosphere above the Netherlands. The oldest measurement tower in Cabauw has been in place for 50 years.
