A CONDENSATION PARTICLE COUNTER FOR LONG-TERM CONTINUOUS USE IN THE REMOTE MARINE-ENVIRONMENT

In order to measure condensation particles of geophysical significance and to detect locally produced airborne combustion products, we modif ied commercial clean room condensation particle counters and deployed these instruments on atmospheric sampling towers in remote marine regi ons. The modified instruments accurately counted condensation particle s in continuous mode both initially and after more than a year of depl oyment with only minor on-site maintenance.
