The goal of the Boreal Ecosystem-Atmosphere Study (BOREAS) is to impro
ve our understanding of the interactions between the boreal forest bio
me and the atmosphere in order to clarify their roles in global change
. This overview paper describes the science background and motivations
for BOREAS and the experimental design and operations of the BOREAS 1
994 and BOREAS 1996 field years. The findings of the 83 papers in this
journal special issue are reviewed, In section 7, important scientifi
c results of the project to date are summarized and future research di
rections are identified.
