DESCRIPTION:Speakers: Prof. CHIKAWA\, Michiyuki (Kinki University)\nAn atm
 ospheric monitoring system has installed at Black Rock Mesa in the Utah\nd
 esert to study the properties of atmosphere using a LIDAR(Light Detection 
 And\nRanging) system and an infra-red(IR) camera for cosmic rays experimen
 t. The aims of\natmospheric monitoring are to calibrate observed cosmic ra
 y's energy and to determine\ndetectable region of the fluorescence detecto
 rs. For these reasons\, the atmospheric\nextinction coefficient and  the c
 loudiness should be determined precisely as possible. \n  The LIDAR system
  consisits of a laser device and a light receiver with a photo\nmultiplier
  tube(PMT) mounting on a steerable base. The laser emits pulse lights\nsuc
 cessively into the atmoshere and the receiver detects scattered faint ligh
 ts by\nthe PMT. To determine the atmospheric extinction coefficient\, a la
 rge amount of data\nhas been\nacquired using LIDAR system at Black Rock Me
 sa commencing from July 2005.A lot of\ndata is analized by means of so-cal
 led the slope method and/or the Klett's method\nafter due consideration of
  atmospheric pressure effect. \nA result consistent with a calculation of 
 the Rayleigh scattering is obtained for the\nvertical extinction coefficie
 nt above an altitude of several kilometres in a calm\nweather. It is also 
 found that the one-dimentional atmospheric density model is\nreasonable as
 sumption on a limitative condition in the Utah desert. \n  The current res
 ults from the atmospheric monitoring with the LIDAR and the IR\ncamera wil
 l be presented in full detail.\n\nhttps://indico.nucleares.unam.mx/event/4
