IceCube Neutrino Meteorology: Correlation Between Atmospheric Neutrinos and Atmospheric Temperature — •Philipp Fürst, Pascal Backes, Jakob Böttcher, Christian Haack, Denise Hellwig, Jöran Stettner, and Christopher Wiebusch — III. Physikalisches Institut B, RWTH Aachen University

The IceCube Neutrino Observatory, located at the Geographic South Pole, measures an all-sky atmospheric neutrino flux. These neutrinos are created in cosmic-ray-induced air showers and their production rate depends on local atmospheric conditions, causing neutrino rate changes throughout the local seasons.

Five years of neutrino data from IceCube and temperature data from NASA's atmosphere-observing Aqua-Satellite are used to measure the correlation coefficient of relative neutrino rate change and relative temperature change.

This correlation coefficient can be used to constrain neutrino production yields of pions and kaons.

We present method and results of calculating the neutrino-temperature correlation coefficient and further outlooks.
