Description
The ARIANNA detector array is a radio-based neutrino detector array consisting of autonomous, solar-powered stations separated by 1km. It is designed to detect neutrinos with energies above $10^{17}$eV that interact with the cold, transparent polar ice. An ARIANNA detector station located near the South Pole has been equipped with 4 downward-facing LPDAs, 2 upward-facing LPDAs, and 2 dipole antennas, and has been taking data from December 2018 to January 2021. We provide a preliminary report on the background characteristics and the improvement in analysis efficiency due to the addition of new hardware and advancement in analysis techniques. We also present a comparison to the results obtained from ARIANNA stations that operated at sea level at Moore's Bay, Antarctica.
