Our online course Observation Theory: Estimating the Unknown starts end of August. If you are interested to learn how to estimate parameters from observational data for real-world engineering applications and assess the quality of the results, this is the course for you.

GRS is back on Iceland for the yearly fieldwork! The equipment has already had a long journey as the devices were sent by boat. Students and staff travelled to Reykjalid as well to measure what is happening at the Krafla and Bjarnaflag areas in the middle north of Iceland. Via their blog you can read all about the activities and everything we do there, so keep posted!

Ice losses from Antarctica have increased global sea levels by 7.6 mm since 1992, with two fifths of this rise (3 mm) coming in the last five years alone.The findings are from a major climate assessment known as the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), to which TU Delft also contributed, and are published today in Nature.

Geo-engineering. The idea is cropping up increasingly often in answer to the question: what can we change on Earth to curb global warming? First and foremost, we must do everything we can to reduce emissions of greenhouse gases around the world. The Paris climate agreement is an important step in the right direction, but more and more studies are showing that the promises made by the signatory countries will have insufficient effect. So we need to find a quicker way to reduce greenhouse gas emissions but, unfortunately, the global community isn't prepared to do that just yet. At some point, we may need geo-engineering whether we like it or not. The sooner we carry out research into the practical aspects of geo-engineering, the possible pitfalls and the consequences, the better prepared we will be for the future.

‘Weather’ is the result of a combination of many diverse factors, such as solar radiation, the concentration of greenhouse gases, air quality and humidity, local building density or vegetation, wind direction and a whole host of underlying physical and chemical processes.

Research by Pieter Smets of TU Delft and the KNMI shows that infrasound can be used for weather and climate forecasts. These inaudible low sound waves can be used to gain a better picture of the stratosphere, which can barely be measured in any other way. On Wednesday 28 March, Smets will be awarded his PhD at TU Delft for his work on this subject.

Rising sea levels are affected by all kinds of different factors, most of which we can now effectively unravel and explain almost everywhere in the world. This is according to TU Delft researcher Thomas Frederikse, who has also established that the average rise in sea levels worldwide is accelerating. Moreover, the days on earth are becoming slightly longer... Frederikse will be awarded his doctorate on Monday, 19 March.

Be the first to see the highly anticipated results of TROPOMI! TROPOMI is a recently launched satellite instrument measuring worldwide air pollution in the most accurate way ever seen before.

Today is the day! TROPOMI heads for space on board the Sentinel-5P payload satellite at 11:27 CEST. It will be launched from the Plesetsk Cosmodrome in Northwestern Russia, with ESA mission control handling operations from Darmstadt, Germany.
