Fine-Resolution Mapping Of Soil Organic Carbon Based On Multivariate Secondary Data
Simbahan, G. C., Dobermann, A., Goovaerts, P., Ping, J., Haddix, M. L.

Our objective was to quantify the improvement in fine-resolution maps of soil organic carbon stock (CS, Mg C ha− 1) resulting from utilizing multivariate sources of secondary information. Different geostatistical techniques for mapping CS in the top 0.3 m of …

Upscaling Fluxes From Tower To Landscape: Overlaying Flux Footprints On High-Resolution (IKONOS) Images Of Vegetation Cover
Kim, J., Guo, Q., Baldocchi, D., Leclerc, M., Xu, L., Schmid, H.

In this paper, we describe the process of assessing tower footprint climatology, spatial variability of site vegetation density based on satellite image analysis, and sensor location bias in scaling up to 1 km × 1 km patch. Three flat sites with different vegetation …

Surface Energy And Carbon Dioxide Fluxes Above Different Vegetation Types Within ABLE
Coulter, R., Pekour, M., Cook, D., Klazura, G., Martin, T., Lucas, J.

Nineteen months of continuous data from two sites within the atmospheric boundary layer experiments (ABLE) facility are used to compare surface energy fluxes, carbon dioxide fluxes and controlling parameters. One site, which has been monitored continuously since 1997, is …

Turner, D. P., Ritts, W. D., Styles, J. M., Yang, Z., Cohen, W. B., Law, B. E., Thornton, P. E.

Net ecosystem production (NEP) was estimated over a 10.9 × 104 km2 forested region in western Oregon USA for 2 yr (2002–2003) using a combination of remote sensing, distributed meteorological data, and a carbon cycle model (CFLUX). High spatial resolution satellite data (Landsat, 30 m) provided information …
