Introduction to special section: BOREAS in 1999: Experiment and science overview

The goal of BOREAS is to improve our understanding of the interactions between the boreal forest biome and the atmosphere in order to clarify their roles in global change. This overview briefly reviews the science background and motivations for the Boreal Ecosystem-Atmosphere Study (BOREAS). The findings of the 27 papers in this journal special issue are reviewed. Important scientific results of the project to date are summarized, and future research directions are identified.
