Astronomy on Tap Leiden: Earth Edition!

April 24, 2023 @ 8:00 PM - 10:00 PM CEST


Our next event will take place on Monday 24 April at Grandcafé de Burcht at 20:00 CEST!

In honour of Earth Day this month, this edition of Astronomy on Tap will focus on observations of the Earth’s atmosphere. We will have two fantastic talks from Jochen Landgraf and Anton Leemhuis who will tell us about how satellites measure greenhouse gas emissions, highlighting the important Dutch contributions to the Twin Anthropogenic Greenhouse Gas Observers (TANGO) mission. As always, there will be fun games where you could win cool science prizes!

Anton Leemhuis – “How can we make a satellite measure greenhouse gas emissions?”

Anton leads the Earth observation activities of the Netherlands Organization for Applied Scientific Research (TNO). His work focuses on working with governments, scientists and companies to realize Earth observation innovations that contribute to a reduction of greenhouse gas emissions and air pollutants and the prevention of biodiversity loss. He is involved in various climate initiatives, such as the Twin Anthropogenic Greenhouse Gas Observers (TANGO) mission under development with Dutch partners. Anton is chairman of Clear Air, a Dutch research consortium for observation of the Earth atmosphere. Previously, Anton worked in various technical and commercial roles for TNO in the Energy sector and was the director of TNO’s Middle-East branch office.

Jochen Landgraf – “It Takes Two to Tango: The Twin Anthropogenic Greenhouse Gas Observers”

Jochen is a senior scientist at SRON Netherlands Institute for Space Research. He is the Primary Investigator of the Twin Anthropogenic Greenhouse Gas Observers (TANGO) mission. At SRON, he leads the trace gas retrieval activities of the Earth Science group with a focus on TROPOMI, S5 and CO2M and TANGO data interpretation. He is a member of the European Space Agency’s Copernicus Sentinel-4, Sentinel-5, and CO2M mission advisory groups and has led and contributed to many international projects, among them several projects for ESA and EUMETSAT. In the year 2021, he was visiting professor at the University Heidelberg. His scientific focus is on atmospheric radiative transfer and measurement inversion techniques. Moreover, his curiosity includes new measurement concepts. For the multi-angle polarimeter SPEXone on NASA’s PACE mission, he leads the development of the L1A-L1C processor, which makes him familiar with algorithms and processing architecture from raw instrument data up to high-level geophysical data products.

Logistical information: We start at 20:00 sharp, so please arrive earlier to enter the bar, save a seat, and grab a drink. We are not planning to stream the event live, but will be uploading a recording of the talks on our YouTube channel after the event.

Join us for an evening of astronomy and fun games where you could win cool science prizes!
