J.M. (Jan) Haacker

Profile

I studied physics at the HU Berlin for the B.Sc. and at the University of Potsdam in collaboration with the Potsdam Institute for Climate Impact Research (PIK).

Since 2020, I do research in the context of my PhD project at the TU Delft.
 

Research

For my M.Sc. thesis at PIK, I studied negative feedbacks important to ice sheet dynamics on a millennial timescale using the Parallel Ice Sheet Model (PISM). Those are driven by isostatic adjustments of the upper earth mantle and characteristics of the sediment.

In the first year of my PhD, I used space-born interferometric synthetic aperture radar (SARIn) altimetry to derive ice mass changes of Iceland's glaciers. Specifically, my expertise is swath processing ESA's CryoSat-2 L1b product.

Since then, I am interested in combining the swath SARIn elevation data with data from NASA's space-born laser altimeter ICESat-2. The research revealed problems that still need to be solved.

Currently, I research uncertainties in swath-processed CryoSat-2 data. I found that over mountain glaciers, two method-intrinsic effects cause issues in the interpretation of the data.
