DESCRIPTION:Speakers: FEDOROVA\, Yulia (University of Utah)\nThe monitorin
 g of atmospheric conditions is very important for \nfluorescence observati
 ons. Particularly\, the presence of clouds can \ndrastically distort the s
 ignal from the extensive air shower. Infra-red \n(IR) sensors\, measuring 
 sky temperature\, can help to distinguish clouds\, \nwhich are usually sig
 nificantly warmer than clear skies. An array of such \nsensors\, covering 
 the HiRes detector's field of view\, was installed\, and \nhas been collec
 ting data every minute of detector operation. Using this \ninformation\, a
  cloud database was created. This database is used to select \ncloud free 
 CR events.  In this paper we present a description of the array \nand the 
 method to analyze IR data.\n\nhttps://indico.nucleares.unam.mx/event/4/ses
