Measuring Alaska’s carbon cycle

A study of carbon dioxide exchange between the Alaskan landscape and the atmosphere finds that current airborne and satellite observation strategies adequately detect shifts in vegetative uptake of carbon dioxide during the summer but cannot sufficiently quantify carbon dioxide release from soil respiration during the cold season, and suggests that year-round sampling across the continental interior is needed to detect the potentially large carbon dioxide release from future permafrost thaw. - Read at
