Open Top Experimental Chambers for Trees

A large, relatively light weight open top experimental chamber was designed, constructed, and tested at the University of California, Riverside. The chamber used the essential basic design principles incorporated into the National Crop Loss Assessment Network chambers. However, because of its unique application for trees, the chamber's structural characteristics are basically of original design. This report describes chamber design, construction, and performance characteristics based on 15 months of operation. The chambers are in use and will continue in operation until the fall of 1986. 5 references, 7 figures, 1 table.
