Temperature Effect of Spatial Distribution of EAS’s Electron Component of the Tunka-Grande Scintillation Array

The paper discusses the technology for temperature correction of the Tunka-Grande scintillation array data. The temperature correction of the density spatial distribution function (SDF) of extensive air shower (EAS) electrons is performed using the data obtained from solving two following problems. The first one is the continuous monitoring of the atmosphere temperature profile in the area where the array is located. It is solved using the AIRS/AMSU-ATMS hyperspectral data from the Aqua and NOAA satellites, along with the calculated predictions of the WRF regional weather model. The second one is the computer complex created and developed by the authors to adjust the Tunka-Grande array readings of the registered EAS to the readings of the standard undisturbed atmosphere. The solution to this problem comes from the sensitivity theory (developed at the Altai State University) of cosmic ray fluxes to variations in atmospheric characteristics. Atmosphere temperature profile variations at the TAIGA observatory location during winter are obtained. It is shown that changes of electron SDFs caused by these variations can exceed ~10 %. The proposed method of temperature correction helps adjust the Tunka-Grande array readings to the readings of the standard undisturbed atmosphere.
