Abstract:
"Tne of the main components of the Large High Altitude Air Shower Observatoryxa0(LHAASO) located in Daocheng, China. WFCTA detects cosmic rays by detecting photons generated by secondary particles of atmospheric showers. Changes in atmospheric depth in WFCTA's field of view will lead to changes in the number of photons in WFCTA. Therefore, the variation of atmospheric depth in the WFCTA is of great significance for the quantitative study of the variation of cosmic ray observation by WFCTA. In this paper, the temporal variation of atmospheric depth at LHAASO is studied based on the MSISE-90 atmospheric model, and the comparison of MSISE-90 atmospheric model with the American standard atmospheric model, satellite experimental data, and meteo data at LHAASO station. We fitted MSISE model data in the operation period of WFCTA to develop a new LHAASO Atmospheric depth model."
