(4)Ecosystem Change Research Program

The objective of this Research Program is to investigate the structures and the functions of terrestrial and marine ecosystems with respect to climatic and environmental changes on a global scale. In particular, it focuses on the observation of the spatial distributions of the biome-characteristic species, biomass, NPP, etc., and on the modeling of material flows and interactions within ecosystems and between the ecosystems, and the atmosphere in wide climatic zones in the Asian-Pacific region and also modeling of material cycles in the oceans involving marine ecosystem.

We are facing the scientifically new problem of how the ecosystem responds to the rapid environmental changes such as CO2 increase or global warming, and at the moment we do not know how it can be predicted or assessed. The Framework Convention on the Climate Change aims to predict, assess and prevent the negative effect of climate change to the terrestrial ecosystem. However, the modeling of ecosystem structures and functions has been behind the atmosphere and ocean circulation modeling.

The final goal of this research program is to develop models of terrestrial and marine ecosystems and to simulate them. However, like other research programs, it starts from the collection and the integration of the basic data and knowledge in the relevant fields.

Qualifications
Candidates having an interest in modeling of ecosystem structures and functions.In particular, candidates having an interest in modeling of material cycles in the oceans involving marine ecosystem, modeling of interactions between terrestrial ecosystem and atmosphere, in modeling of ecosystem changes responding climate change, and in modeling and observation of spatial and temporal dynamics of ecosystem parameters.

1)Ecosystem - Atmosphere interaction modeling group

2)Ecosystem geographical distribution modeling group
Candidates having an interest in observation and modeling of ecosystem structures and functions, and having basic knowledge for remote sensing and GIS.

3) Marine biological process modeling group

4)Individual researchers who are interested in ecosystem dynamics in general, from perspective viewpoint. Interests on item 1 to 3 are also required.



(5)Global Warming Research Program

This research program explores the physical and chemical mechanism responsible for global warming and attempt to make quantitative projection of future climate change. It covers three research subjects, i. e., global warming, coupled model development, and paleoclimate.

1)Global Warming Research
Using a hierarchy of climate models with various complexities and computational resolutions, the future changes of climate and the physical mechanisms, which are responsible for these changes are studied. For example, using general circulation model of the atmosphere with very high computational resolution, we will explore how those phenomena which are important for climate such as tropical and extra-tropical cyclones and El Nino-Southern Oscillation, are affected by global warming.

2)Coupled Model Development
Coupled atmosphere-ocean-land model is an extremely important tool used for studying the highly complex climate system. This program will conduct various numerical experiments using the existing coupled model running on the Earth Simulator. The results will be analyzed and compared with the observational data in order to improve understanding the mechanism of the climate and climate variability. Also, the performance of the model, especially its weaknesses will be evaluated in order to improve the model.

3) Paleoclimate Research
Using a hierarchy of climate models with various complexities, the mechanisms which are responsible for past climate changes, in particular, the glacial-interglacial transition of climate are studied. For example, we will explore how the massive continental ice sheets were maintained during the last glacial maximum and why they have been reduced to the modern ice sheets of Greenland and Antarctic Continents. Based on this study we will also attempt to determine the future of these ice sheets.

Qualifications
The major objective of this program is the predictive understanding of global climate. It seeks those candidates who are interested in modeling study of the research topics identified above. It is desirable that they have basic knowledge of mathematics, physics, and chemistry, and the ability to apply the‚ to the study of climate. In particular, the program looks for those who are interested in developing climate models and using them for the study of climate.



(6)Global Environment Modeling Research Program

The mission of the Program is to develop "new" climate models, global environmental models and ocean data assimilation systems to be run on the world's fastest "Earth Simulator" which was completed in March 2002. The following are the present targets of development:

1. Atmosphere model with a horizontal mesh size of 5 km or less by which tropical cloud clusters and other meso-scale atmospheric systems can be represented explicitly. Similarly, eddy resolving world ocean model are being developed. As the coordinate system to cover the globe cubic-grid and incosahedral-grid (quasi-uniform grids) are adopted.

2. Development of models to include new elements such as aerosols effects on clouds, or global carbon cycle, on the basis of currently existing climate models cooperating with other research programs.
Development toward this "Integrated Earth System Model" starts from FY2002 as apart of the MEXT new project described in (7).

Modeling experts now being sought are expected to be engaged in
-Development of higher resolution atmosphere models on the basis of existing models by improving treatments of various physical processes, especially the atmospheric boundary layer and cumulus convection
-Development of high-resolution world ocean circulation models
-Development of non-hydrostatic atmosphere models
Computer experts having experiences in climate models’ coding for parallel machines are also being sought.

In addition to the above described model development, ocean data assimilation systems are also developed in this program. Four-dimensional variational data assimilation systems, which incorporate satellite and in-situ observational data into numerical models, are the subject of increasing interest. These can provide realistic initial conditions for adequate prediction and also useful re-analysis datasets for accurate estimation of ocean circulation processes. A variational data assimilation system using the adjoint method is the most promising approach in view of the fact that the spatio-temporal coverage of the present measurements for mass and velocity fields is far from complete. We have therefore constructed a global ocean data assimilation system and are now in the process of pursuing the following research subjects:
1) Improvement of the global ocean data assimilation system by using the adjoint method and Kalman filter
2) Research and development of high resolution data assimilation system utilizing satellite data and in situ data (TRITON/TAO, ARGO), together with development, processing and analysis of high-quality data set, which enable us to trace the time evolution of El Nino and other phenomena.

We invite applications from specialists for the above work.


(7)MEXT Project for sustainable coexistence of human, nature and the earth

From FY2002, three projects started under "MEXT Project for sustainable coexistence of human, nature and the earth". In the coming fiscal year, we invite applicants for the following project.

<<Development of Integrated Earth System Models>>
In recent years, with the increase of societal need for global warming prediction, projection of the future of the CO2 sequestration by land ecosystem under changed climate conditions is much concerned about and coupled carbon cycle-climate models are now being developed at some research centers.

At FRCGC we have initiated a new research project to develop "integrated earth system model" in response to the AO of the MEXT project. The basic strategy of development is to couple component models already existing in respective research programs through collaboration of members of the new project with research scientist of existing programs and then improve the coupled model through investigation of dynamics of the coupled system to complete the model mostly by the new project members. We plan to carry out global warming experiment by developing coupled carbon cycle-climate models within 1-2 years. We also plan to include more components such as atmospheric chemistry, ecosystem dynamics and so on step by step.
