Artificial Cloud Formation in the Atmosphere

An artificial cloud in the cloudless atmosphere at a temperature below 0°C was formed by introducing pellets of Dry Ice into air containing more water vapor than would be present at the saturation point with respect to ice. Such clouds could be utilized to establish radiative equilibrium between gro...

Description
Summary:An artificial cloud in the cloudless atmosphere at a temperature below 0°C was formed by introducing pellets of Dry Ice into air containing more water vapor than would be present at the saturation point with respect to ice. Such clouds could be utilized to establish radiative equilibrium between ground and air so as to inhibit the cooling of selective arctic surface regions under clear skies.
