Brasilien-Projekt

Bild zum Projekt Brasilien-Projekt

Supervisor:

Prof. Dr. Gunther Seckmeyer (IMUK), Dr. Fernando Ramos Martins (UNIFESP)

Researcher:

Angelika Niedzwiedz, Eduardo Weide Luiz, Marcelo Pizzuti Pes, Sonja Veith

Duration:

2016-2018

Brief description:

Solar energy production has a very high dependence by the varying solar elevation. The diurnal variation of solar power with all panels oriented southward/northwards (depending on the Earth’s hemisphere) does not match well with the daily electricity load curve. The project’s aim was to test different orientations in order to match the load and supply energy curves in both Germany and Brazil. Since electricity prices depend on demand, this new approach can be more economical, resulting in lower energy prices for consumers, improving energy security for a more sustainable progress.

Bild zum Projekt Model-based city planning and application in climate change (MOSAIK)

Supervisor:

Björn Maronga, Günter Groß, Siegfried Raasch, Gunther Seckmeyer

Researcher:

Tobias Gronemeier, Matthias Sühring, Farah Kanani-Sühring, Jungwha Lee, Robert von Tils, Michael Schrempf

Duration:

2016-2019

Funded by:

BMBF

Brief description:

The goal of the project is the development of a new innovative urban climat model that is able to simulate the microclimate in densely-populated cities like Berlin with a spatial resolution of less than 10 m. The model will be developed as a user-friendly tool, which can be applied by both scientists and urban planners..

Investigation on reflection properties of snow (IREPS )

Bild zum Projekt Investigation on reflection properties of snow (IREPS )

Researcher:

Ansgar Stührman, Michael Schrempf, Stefan Riechelmann, Gunther Seckmeyer

Duration:

03/2014 - 02/2016

Funded by:

Bundesministerium für Bildung und Forschung (BMBF)

Brief description:

In cooperation with our Chilean partners reflection properties of snow covered surfaces typical for the Alps, the Andes or Antarctica will be investigated. Therefore a new multispectral spectroradiometer shall be developed to measure the spectral sky radiance from about 120 directions within a wavelength range of 280 nm – 600 nm simultaneously.
