Wind field characterization at lake Heideweiher

Since recently, atmospheric research is taking place at the lake Heideweiher near the village Hopsten in the very North of Northrine-Westphalia, Germany. Or should we say within the lake Heideweiher? In the surrounding natural reserve area numerous environmental research projects are carried out for many years. Also, one of our research groups at the Institute of Landscape Ecology, namely the Ecohydrology and Biogeochemistry Group, is involved. In cooperation with them and complementary to their methane flux measurements with chambers, we are interested in quantifications concerning the turbulent atmospheric fluxes of methane, one of the most important greenhouse gases besides CO2, using the eddy-covariance technique at the site. Therefore, an eddy-covariance tower has been installed at the bottom of the lake equipped with an ultrasonic anemometer. The installation process was plain and simple at the time since the lake was dried-out almost completely due to the drought in Germany this summer. With a preliminary study running, the expected to be complex wind field will be investigated during the next weeks.

Prof. Klemm no longer active in the climate council of the city of Münster

At the beginning of November 2018, Prof. Klemm told the Mayor of the city, Markus Lewe, that he had left the Climate Council. "In the seven years since the reorganization of the Climate Council, in which I chaired, I have not been able to develop the Climate Council into a body of importance in the city of Münster." Repeated suggestions from the Climate Council, for example, to the sustainable redesign of the Former barracks area "York" (Gremmendorf) and "Oxford" (Gievenbeck), where many hundreds of new apartments will emerge, found little echo. "After weighing public and private concerns against each other and with each other, the ... statements were not followed," was one example vile, written answer to detailed proposals of the Climate Council. Debate with the climate council on contents hardly took place.

  As early as the summer of 2018, Prof. Klemm announced internally that he would not continue to chair the Climate Council. However, the regular election in November 2018 went awry, as no candidate and no candidate for succession could be found. The vice-chairmanship also remained vacant. The Climate Council seemed paralyzed at this time. As a consequence, Prof. Klemm declared that he would leave the Climate Council. "I do not like doing that, but I have no choice. Maybe under other circumstances a successful reboot succeeds. "It requires a rethinking of some political representatives of the city and parts of the administration to help climate protection in Muenster to the importance that it needs.

  Münster wants to reduce its CO₂ emissions by 95% by 2050. The EU has committed to reduce it by 80% to 95%. The latest report of the IPCC (IPCC) to comply with the 1.5-degree target (Oct 2018) calls for a reduction in emissions to virtually 100% by 2050. Otherwise, dramatic further consequences for the world's population are expected. "Germany as an industrialized nation and especially those municipalities that have committed themselves to climate protection must make headway here," says Prof. Klemm. Against this background, there can be no other consideration than planning todays new buildings (keywords: York, Oxford) to emit no greenhouse gases in 2050! However, this does not seem to be considered. Prof. Klemm emphasizes that there is sufficient expertise in the politics and administration of Münster, and for many the willingness to consistently implement climate protection. Alone lack of consensus, the climate among other important aspects (social, financial, ...) grant the status of a guardrail of urban development. The role of the climate council has been marginal so far. Maybe a successful restart succeeds. Good luck!

New field trips

In the summer of 2019 an excursion to Taiwan will be offered. The excursion will take place from 20.07.2019 until 02.08.2019 and will focus on climatological aspects. Also the landscape, geology and culture are considered to get an unrestricted view of the country.
This semester a one-day excursion to Essen takes place. We will visit the German Weather Service (DWD) with the associated measuring field and the State Office for Nature, Environment and Consumer Protection NRW (LANUV). The excursion takes place on 07.02.2019 and there are no costs if a semester ticket is available. On 12.03.2019 there will be a one-day excursion to the German Weather Service in Offenbach and the EUMETSAT in Darmstadt. 20 Euro will be charged for the trip. For more information in english, please contact Prof. Klemm.

New investigations on air quality in Münster

A new measurement campaign to determine urban air quality started at the end of August at the Bült, a busy street in the city center of Münster. The project „LUFTHY“ founded by the DFG includes continuous measurements of carbon dioxide, ammonia, nitrogen oxides and tropospheric ozone as well as ultrafine particles in the range between 6 nm and 10 µm at a high temporal resolution. We also collect additional information about the passing vehicles using a microphone and special cameras.
The results will help to determine the relationship between traffic-related emissions of gaseous air pollutants and ultrafine particles and the characteristics of the vehicle fleet (e.g. emission classes). On the long run, this project should contribute to the enhancement of atmospheric model predictions and help to mitigate urban air pollution.

Bettina Breuer has been conducting fog measurements at the Lulin Atmospheric Background Station in Taiwan since mid-August. With the help of an active fog collector, fog water samples are taken automatically and with high temporal resolution, which are then analyzed for their ion composition. In addition, a new aerosol spectrometer is being used for the first time to measure the size distribution of mist droplets. Some exciting fog events have already been recorded.

Update for "MünsterWetter" App

The "MünsterWetter" App provides the data of the weather station on the roof of the institute building. Unfortunately, the app had some dropouts that have been fixed by an update. The update is available in the Google Play Store for Android operating systems.

field trip to Essen

On 22th of february a field trip to the German Weather Service (DWD) and the State Office for Nature, Environment and Consumer Protection (LANUV) in Essen took place. At the DWD, the students had the opportunity to get to know the regional weather consultants and to experience the launch of a radiosonde at the measuring field. The LANUV provided insights into its wide range of tasks and in particular explained the monitoring of air quality in NRW. In addition, insight into the vehicle of the "Sondereinsatz" was granted. The on-call service maintained by the LANUV examines hazardous emissions in the event of damage on site.
