And I Iike to emphasize a key technical issue. Generally ecosystem studies start from very local and regional objects so that how to scale-up from local to global is a very important aspect in global ecosystem modeling. As Dr. Manabe talked yesterday observational models are important. In our field observational data are very much lacking so we have to integrate observation data first. So this is the scheme (not shown) to integrate data; the ground level observation, tower level observation, closed biosphere observation, aircraft observation and satellite observation. All these data are needed and the data should be fed to models and simulators. So we have to clarify the flow from this.
In order to do these we need collaboration with many other organizations. The first is NASDA. It is already highlighted how important satellite observation is. It is particularly true in our ecosystem research field both for land and ocean ecosystems. Without remote sensing data we cannot have a good model. Thus we need collaborations with NASDA and other space agencies in the CEOS framework. And also need collaboration with in situ observation group, Asiaflux, Euroflux and also long term ecological research sites. Well this is my personal idea that we need to establish some center for dealing with Asian issues; Asian center for ecosystem research or something; we need that kind of organization. We have here in the FRSGC ecosystem modeling and simulation, so we need observation; I hope that ecosystem program is established in the Frontier Observational Research System.
Dr. Motoyoshi Ikeda (FRSGC'S Program for IARC):
My way of presenting research strategies or the road maps at the International Arctic Research Center at Fairbanks is like this. I show on the left (not shown) important processes: stratus clouds, dense water formation and so on. Then simultaneously we look into the Arctic oscillation, decadal variability and so on. We then investigate these in atmospheric model, sea ice-ocean model and so on by using existing models or developing those models. From here we go toward a coupled model and feeding it in the global model, which includes important processes such as the dense water formation in the Greenland Sea. This is the entire strategy at the IARC.
In addition to this IARC strategy I like to make a suggestion for modeling study at the entire Frontier. That is, 3 core projects in modeling study: Modeling of climate variability from seasonal, decadal to centennial scales using a coupled model.
