The ability to absorb, store and emit heat, water, greenhouse gases and pollutants are essential ecosystem services. However, observations and numerical simulations of these processes are often made at different spatial and temporal scales. This limits our ability to evaluate models, develop efficient data assimilation techniques, and ultimately to forecast the spatio-temporal distribution of corresponding stocks and exchanges. For example, what considerations are needed to link ecosystem exchange observations (10^−6–10^1 km^2) to gridded land-surface models (10^2–10^4 km^2) and how can we quantify the associated uncertainty? This session focusses on advances in upscaling and downscaling techniques that link surface-atmosphere exchange observations to models. We welcome contributions that quantify, map, or aggregate spatio-temporal patterns across scales, thus improving conceptual and quantitative understanding. Especially encouraged are studies that focus on spatio-temporal hierarchies of observations, combinations of mechanistic, data-driven, and other modeling approaches that explore the spatial patterning at model sub-grid scales. co-sponsor with: A, GC, H ------------------------------------------------- Ankur R Desai, Associate Professor on sabbatical leave (2013-2014) from University of Wisconsin - Madison, Atmospheric and Oceanic Sciences http://flux.aos.wisc.edu [email protected] +1-608-218-4208 -or- +49-152-36773296 Current address: KIT IMK-IFU, Kreuzeckbahnstraße 19, 82467 Garmisch-Partenkirchen, Germany
