DESCRIPTION:Speakers: Dr. MISHEV\, alexander (Institute for Nuclear Resear
 ch and Nuclear Energy\, Bulgarian Academy of Sciences)\nThe transparency i
 s one of the primary measures of the atmospheric state. The precise\nlong 
 term series of atmospheric transparency measurements gives the possibility
  for\nquantitative estimate of the variability of air circulation and to m
 ake climatologic\nconclusions with regard to contamination\, cloud formati
 on\, humidity and radiative\nexchange. It seems to be possible to estimate
  the atmospheric transparency on the\nbasis of atmospheric Cherenkov light
  registration and corresponding Monte Carlo\nsimulations. Measuring the Ch
 erenkov light flux produced in extensive air shower in\ndifferent atmosphe
 ric conditions one obtains different amplitude spectra. This\nreflects on 
 the slope of the reconstructed spectrum. The different slopes of the\nreco
 nstructed spectra correspond obviously to different atmospheric conditions
 . In\nthis work are presented several CORSIKA simulations of the expected 
 density spectra\nat sea level and high mountain altitude observation level
 s. Several preliminary\nmeasurements with atmospheric Cherenkov telescope 
 and estimates are shown. The\npossibility to study different atmospheric p
 rofiles is discussed.\n\nhttps://indico.nucleares.unam.mx/event/4/session/
