Micrometeorology Research at ASRC

Researchers:  Scott Miller

Researchers at the ASRC are using micrometeorology to address outstanding questions of exchange between the atmosphere and land or water surfaces. Four projects, both continuing and new, demonstrate the use of direct flux measurements to address important science questions: 1) the flux of dimethylsulfide, acetone and carbon dioxide over the open ocean and the relative importance of air- and water-side resistance to gas exchange; 2) the effect of selective logging on carbon dioxide, water vapor and energy exchange above a tropical rainforest; 3) the physics of momentum and energy exchange above deep ocean waves; and 4) the role of carbon dioxide evasion from rivers in the Amazon basin in the regional carbon budget. This broad range of topics has required collaborations with physical and chemical oceanographers, ecologists, hydrologists, and meteorologists. The measurements have been made using commercially available instruments in novel configurations, and, more recently, incorporating new trace gas measurements.
