msc projects 2020 - vmp
TRANSCRIPT
Three MSc projects are available in 2020,
to be based at Physikalisch-Meteorologisches Observatorium Davos /
World Radiation Center (PMOD/WRC). https://www.pmodwrc.ch/
PMOD/WRC has been studying the influence of the Sun’s irradiance on the Earth’s climate since 1907. In order to do this, ground-based instruments and space-based instruments are designed, built, calibrated and operated. Three projects are available this year for MSc students at ETH. These range from working hands-on with space instruments to analysis of long-term ozone data, to climate modelling. Since 2019, the director of PMOD/WRC is also an affiliated professor at ETH, opening new opportunities for MSc projects. Come and join us in Davos!
Topic: Aerosol modeling
Raikoke eruption modeling
Key questions: • How well does our model simulate volcanic plume? • What are the atmospheric impacts of eruption?
Key tasks: Perform model experiments, compare results with ground- and satellite-based observations. Methods: Data analysis and statistics. And you will learn how to operate global climate models and related necessary tools.
Topic: Volcanic eruptions represent some of the most climatically important and societally disruptive short-term events in human history. Even though recent eruptions were not very strong, they are better observed than big eruptions of the past, which allows to learn more about related physics and to improve our models.

Topic: Solar Radiometry
Electric characterization of space hardware
Key questions: • How accurate are the measurement circuits of the DARA
radiometers to fly on FY-3E and PROBA3? Both these missions will be launched in 2020-2021.
• Which are the largest contributions to the measurement uncertainty and how can they be reduced?
Key tasks: Perform pre-flight electric measurements with the DARA solar radiometers and compile a detailed uncertainty budget of the measurement chain. Methods: Data analysis and statistics. And you will learn how to manipulate and operate space hardware.
Topic: Solar irradiance is the only significant energy source for the Earth’s climate system. The solar irradiance is measured with radiometers on spacecraft. In order to measure in absolute units (Wm-2) the on board measurement circuits need to be characterized and tested before launch.

Topic: Ozone study Does total ozone over Arosa/Davos station represent the global ozone field? How representative is Arosa/Davos for monitoring the global ozone recovery?
Key questions: • What is the correlation of TOC over Arosa/Davos with
other locations over the globe? • How does the correlation depend on season and future
ozone evolution? • How many stations and in which locations are necessary
to estimate global TOC? Key tasks: Analysis of the available results of model experiments and ground-based and satellite observations. Methods: Correlation analysis and other statistical methods.
Topic: The monitoring of Total Ozone Content (TOC) is required to trace expected future ozone recovery as well as to understand the ozone behaviour in the past. Long term time series of ozone measurements from Arosa/Davos station are available. Can this provide the necessary information to judge about the global ozone layer recovery.
