New publications

The global climate model CESM simulates contemporary Antarctic surface climate quite right, and suggests a more intense hydrological cycle in the future over the coldest continent on Earth. Read all about it here (open access)..

[Nov. 2016] New website

This website will not be updated anymore, since I have transferred it to University of Colorado webspace. Click here to access my new website

[Jul. 2016] Prepare to move

I will start a tenure-track faculty position at the Department of Atmospheric and Oceanic Sciences (ATOC) of the University of Colorado, Boulder (USA) next year (summer 2017). In the meantime, we are preparing for new CESM2 simulations (including most recent snow and atmospheric physics) that will (hopefully) allow for a realistic ice sheet mass balance. Exciting times!

[Oct. 2014] InBev-Latour Antarctica Fellowship - Melting of East Antarctic ice shelves

In September, I was awarded the InBev-Latour Antarctica Fellowship. This grant allows me and my colleagues to perform fieldwork during two consecutive seasons, close to the Belgian Princess Elisabeth base in East Antarctica. For a more complete description of the project, and the latest news, please visit this blog.

[Jul. 2014] Veni award: improved modelling of the current and future polar snow cover

I am happy to be one of the Veni awardees: I receive a 250 000 euro grant that enables me to do three years of independent research. I will focus on improving the snow representation in a fully-coupled, high-resolution Earth System Model (CESM), and analyze the interactions between polar snow and the remainder of the climate system. I will remain based at Utrecht University (IMAU) and collaborate with climate scientists from all over the world.

[Feb. 2014] Drifting snow observations on Greenland

The drifting snow observations performed on the Greenland Ice Sheet are now analyzed, and a paper summarizing the first results is now published (open access) in The Cryosphere Discussions. The movies below show the animated autonomous camera snapshots from the period under study (September 2012). Several drifting snow events were detected during this period.

[Jul. 2013] Ice mass loss acceleration undetectable

Led by Bert Wouters, we have published a new study on the detection of ice mass loss (Paper: acrobat logo). The main conclusion is that, due to the limited time period of Earths gravity changes and large temporal climate variability, it remains uncertain that ice mass loss is accelerating. We need at least 10-20 years of additional GRACE measurements before the observational time period is long enough to detect accelerations with sufficient certainty.

A newspaper article on this topic (in Dutch) was published in NRC Handelsblad (20 July 2013): acrobat logo
