The following lists contains active research questions in my personal research and that of my group members. This is the state of 2015/2016.
Original and reconstruction by direct sampling with volume Bessel potential inversion from a far field pattern of uniform sources located in the rectangle, here using 7 different frequencies (left), using four frequencies between wavenumber 1.5 and 2.5, one incident field only (right). This is work in progress.
Radar Data Assimilation based on an Ensemble Kalman Filter in a Convection Permitting Model with Rapid Update Cycle. We show the influence on the cycling frequency on the fractional skill score. Here, for the 4d-Version of the LETKF, lower update rates lead to better fractional skill skores after one hour of forecast.(left) Further, we compare latent heat nudging with full Volume Radar assimilation (right) - they were of comparable quality in these experiments. The experiments have been carried out by Bick et al.
