Some Temperature Effects on the Supersaturation in a Thermal Diffusion Chamber.

Abstract

The report contains experimental information on the temperature characteristics and their effect upon the supersaturation in the thermal diffusion chamber (TDC) of the Cloud Condensation Nuclei (CCN) Collection Detection Recording Instrument used at the Atmospheric Sciences Laboratory, White Sands Missile Range, New Mexico. Four experiments were conducted to determine the extent to which the supersaturation was being influenced by changes in top and bottom plate temperatures and the temperature difference. It was shown that the greater the temperature difference between the plates, the greater the effect of the top plate temperature change on the supersaturation. It was concluded that the sampling flow rate of air through the chamber that had the least effect on the temperature change was 400 cc/min. The overall effect on the supersaturation in the chamber was negligible. (Author)
