Abstract: The standard practice of using moderate resolution satellite imagery for carbon flux studies at Ameriflux sites is called into question. In this study, a flux footprint model was implemented for modelling the carbon source areas for an Ameriflux site in Oklahoma using one year of carbon flux and meteorological measurements. A sensitivity analysis was conducted using cell sizes from 1 m to 30 m for the study site. The results indicate that over 95% of the source locations are within 93 m of the carbon flux receptor. Knowing the spatial accuracy is typically no better than ½ cell size, suggests that cell sizes of less than 45 m introduces far greater uncertainty than is appropriate.

The Journal for Geographic Information Science issue 1-2015 presents peer-reviewed papers
presented at the Geoinformatics
Forum (www.gi-forum.org), held in Salzburg from July 7-10,
2015. The annual GI_Forum symposium provides a platform for dialogue among geospatial minds
in an ongoing effort to support the creation of an informed GISociety.
