Abstract content

Extensive air shower (EAS) observation has been performed by the compact and synchronized EAS arrays by LAAS experiments. The zenith angle distribution and atmospheric effects were examined in order to obtain EAS absorption coefficients in the air and the relation between them and spectral index. The atmospheric effects are going to be analyzed as function of local solar time in harmonic analysis. The emperature and barometric pressure effects are clearly reproduced in the meterological diurnal variation. We are going to discuss on these effects and corrections.
