Over the last 25 years, radiowave detection of neutrino-generated signals,
using cold polar ice as the neutrino target, has emerged as perhaps the most
promising technique for detection of extragalactic ultra-high energy neutrinos
(corresponding to neutrino energies in excess of 0.01 Joules, or $10^{17}$
electron volts). During the summer of 2021 and in tandem with the initial
deployment of the Radio Neutrino Observatory in Greenland (RNO-G), we conducted
radioglaciological measurements at Summit Station, Greenland to refine our
understanding of the ice target. We report the result of one such measurement,
the radio-frequency electric field attenuation length $L_alpha$. We find an
approximately linear dependence of $L_alpha$ on frequency with the best fit of
the average field attenuation for the upper 1500 m of ice: $langle L_alpha
rangle = big( (1154 pm 121) – (0.81 pm 0.14) (nu/$MHz$)big)$ m for
frequencies $nu in [145 – 350]$ MHz.
