Carbon, water, and energy flux were measured in a complex urban environment with relatively high vegetation cover. Analysis using wind direction from different land uses shows that higher vegetation cover having more C uptake, less C emissions, and lower land surface temperatures, providing beneficial ecological services. Investigations into partitioning of carbon emissions and carbon uptake dynamics shows interaction of anthropogenic emissions with land use, existing tree cover and lawns. Maintained vegetation may have a large impact during the summer growing season. Repeat measurements of established tree plots around the tower for carbon gain were found to be highly variable due to tree removals. Non-destructive methods for volume and biomass estimates using 3D terrestrial scanning lidar on individual trees were initiated.
