Abstract

A transmissometer has been installed at the H.E.S.S. site to supplement information on atmospheric absorption obtained by a LIDAR operating at 905 nm. The transmissometer monitors the absorption at this LIDAR wavelength and at 3 shorter wavelengths for the lowest 550 m of the atmosphere. The relationship between the absorption measurements and the triggering rate due to air showers produced by hadronic cosmic rays is investigated with the aim of refining the measurements of flux and energy spectra of gamma ray sources. In particular when searching for source variability, the detection of any changes in Cherenkov light extinction is of crucial importance.
