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.

Paco Lopez Dekker: Bij NASA zijn ze jaloers op wat wij in Europa doen

Paco Lopez Dekker: Bij NASA zijn ze jaloers op wat wij in Europa doen

In 2029 gaan twee Europese satellieten voor aardobservatie de ruimte in. Paco López-Dekker is hoofdonderzoeker van de missie. López-Dekker is aan de TU Delft hoofdonderzoeker van een satellietmissie die de Europese ruimtevaartorganisatie ESA afgelopen september selecteerde als de 10de Earth Explorer. Dat zijn missies met als doel te monitoren hoe processen op aarde veranderen door mensen. López-Dekker is de eerste Nederlandse hoofdonderzoeker van een Earth Explorer. Samen met zijn team bedacht hij de Harmony-missie en nu begeleidt hij de ontwikkeling ervan.

Modern life now often depends on GPS (short for Global Positioning System), but it can err by several meters in cities. Now a new study from a team of Dutch researchers reveals a terrestrial positioning system based on existing telecommunications networks that can deliver geolocation info accurate to within 10 centimeters in metropolitan areas.

Christian Tiberius in het AD: Nooit meer de weg kwijtraken

Wie kan er nog navigeren zonder gps? In grote steden met veel hoogbouw verdwaal je makkelijk doordat gps niet altijd vlekkeloos werkt. Door satellieten te vervangen voor een speciaal mobiel netwerk is de weg kwijtraken bijna niet meer mogelijk

Christian Tiberius in het NRC: Plaatsbepaling tot op 10 cm precies

Plaatsbepaling met gps is in de praktijk niet heel nauwkeurig. Het kan beter, door geen satellieten maar 5G-masten te gebruiken.

Roderik Lindenbergh & Mieke Kuschnerus laser scan data set of Kijkduin

Nature Portfolio’s Scientific Data Journal published an article written by Sander Vos, Katharina Anders, Mieke Kuschnerus, Roderik Lindenbergh, Bernhard Höfle, Stefan Aarninkhof and Sierd de Vries, that describes a 6 month long hourly laser scan survey of the beach-dune system at Kijkduin, The Netherlands. The Netherlands is protected by about 250 kilometers of natural beach-dune systems and understanding the natural variability and resilience is of key importance to protect the Netherlands with the future climate change and sea level rise. The dataset provides information about storm responses and shoreward sand transport which is important for the resilience determination.
