Polarimetric phase-sensitive Radio Echo Sounder (PpRES) measurements at EastGRIP drill site on the Northeast Greenland Ice Stream. PpRES_CL are measurements from the science trench next to the core location (CL) roughly 8 m below the surface. The other measurements (PpRES_GRID_C, PpRES_GRID_N, PpRES_GRID_E, PpRES_GRID_S and PpRES_GRID_W) were performed within a 20x20 m^2 grid (named GRID) approximately 360 m from the drill site. The transmitting and the receiving antenna of PpRES_CL were aligned with vertical polarisation (VV) at an azimuthal angle of roughly 258° clockwise to magnetic North (283° true North). The antennas of GRID-measurements were aligned at an azimuthal angle of roughly 168° clockwise to magnetic North (193° true North). The file names include the degree of the measurement representing the orientation of the antennas (clockwise rotation) to the originally pointed angle. The referenzed figure visualises all antenna orientations along with two types of notation.
