Description:
In this paper, we describe a new experiment with a SF6 tracer to determine the mixing history of a small region of cloud-base air. n situ measurements of the SF6 are made to follow the egion and simultaneous measurements of natural trace gases are used to determine the dilution of the tagged region as it is affected by the cloud. fter describing the experimental method, the results from an experiment with a small cumulus, which was ideally suited for this experiment, are described. his paper is intended to demonstrate the usefulness of this approach and to lay the groundwork for future experiments. he goal is to better understand how convective clouds redistribute trace constituents (e.g. moisture, trace gases) in the vertical.
