A study of the effect of molecular and aerosol conditions in the atmosphere on air fluorescence measurements at the Pierre Auger Observatory

Mostrar todas las versiones(2)

The air fluorescence detector of the Pierre Auger Observatory is designed to perform calorimetric measurements of extensive air showers created by cosmic rays of above 10 18 eV. To correct these measurements for the effects introduced by atmospheric fluctuations, the Observatory contains a group of...
