Roger Carter has been investigating some of the newer halocarbons that are becoming available for their suitability as possible atmospheric tracers. These halocarbons are starting to be used as refrigerants and foam blowing agents, and they have relatively low global warming potentials.Cost, reactivity, and compatibility with existing equipment are some of the factors being investigated.

The manuscript “Mechanisms for Wind Direction Changes in the Very Stable Boundary Layer” by D. Finn, R. M. Eckman, Z. Gao, and H. Liu received overall favorable reviews after its submission to the Journal of Applied Meteorology and Climatology. It is undergoing minor revisions and will soon be returned to the editors.
