Climate, glaciers, and scientific programming.


My research interests are broad and varied, and I particularly like to mix and merge methods and models across disciplines. Here are some of the topics I am interested into:

Climate controls on glacier mass-balance

Figure: monthly mass-balance of the Shallap Glacier (Peru) at 4750 m a.s.l as computed by a statistical model linking the large scale atmospheric circulation to the local glacier surface energy and mass balance (Maussion et al., 2015)

Relevant publications: Maussion et al., 2015; Mölg et al., 2012; Mölg et al., 2014

Glaciological modeling at regional and global scales

Figure: Example of the OGGM pre-processing workflow applied to the Tasman glacier, New Zealand: (a) definition of a local map and computation of the center lines; (b) computation of the glacier geometrical widths; (c) inversion of the glacier thickness using a mass-conservation and ice-flow modelling approach; (d) spatial interpolation of the ice thickness.

Relevant publications: in preparation

Climate of the Tibetan Plateau

Middle: atmospheric water transport towards the Tibetan Plateau in July plotted along cross-sections of the Himalayas (Curio et al., 2015). Right: Wind vectors and geopotential height in July as computed by the HAR (Maussion et al., 2014).

Dynamical downscaling with the WRF model

Interdisciplinary approaches

Left: ice cover duration for several lakes on the TP obtained from remote sensing data (Kropáček et al., 2013). Middle: monthly lake Level changes as observed and as simulated by a modelling tool combining atmospheric and hydrological models (Biskop et al., 2016). Right: mean shear velocities (colour scale) and wind direction and speed over the Tibetan Plateau in summer illustrate the complex patterns of sediment transport into selected tibetan lakes (Dietze et al., 2014).

Open science

I am fascinated by the opportunities offered by sharing our data and methods more efficiently and more transparently. I am an enthusiast open-source programmer, and most of the research data and the publications I contributed to are open access.
