2006 Announcement of Research Positions for Frontier Research Center for Global Change (FRCGC)

Please mind that following information is run as a reference. Applications for those positions have been closed.

1. Objectives of FRCGC  
Global changes, such as global warming and climatic anomalies, are serious problems which affect the ecosystem of nature and the future of human beings. Predicting global change through better understanding of these global phenomena are pressing issues. At FRCGC we attempt to understand the complicated interactions among the atmosphere, ocean and land surface and to develop models capable of more accurate simulation of global scale phenomena. To accomplish these objectives, we propose the following research assignments, and invite excellent foreign as well as Japanese research scientists for an intensive period of research.

2. FRCGC and related organizations
FRCGC is a research center within the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) which was established April 2004 by transformation of the former FRSGC. It is one of the three sister Centers which includes Frontier Observational Research System for Global Change and the "Earth Simulator", Center which was completed in March 2002. Researchers at FRCGC can access the Earth Simulator, the world's fastest supercomputer.

3. Research Programs and applicantsrequired
In the coming fiscal year, we invite applicants for six research programs (Climate Variations, Hydrological Cycle, Atmospheric Composition, Ecosystem Change Global Warming, and Global Environment Modeling).

(3) Atmospheric Composition Research Program
 This program carries out model prediction research and observational research necessary for it on the variability of atmospheric composition including both long-lived greenhouse gases such as carbon dioxide and methane, and short-lived atmospheric constituents such as aerosols, ozone and their precursors, that cause climate and air quality change directly and indirectly. Future researches are directed toward improvement of precision of source/sink estimates of greenhouse gases and other atmospheric trace species by high resolution inverse modeling, chemistry-climate interaction by ozone and aerosols, inter- and intra-continental transport and hemispherical air pollution, development of chemical weather forecast system combining global, regional and urban scale models, satellite data analysis of tropospheric chemical species aiming at evaluation of climate and environmental impacts of anthropogenic activities in Asia.

Observational research focuses on continuous measurements and intensive campaigns of aerosols, ozone and their precursors in China, an intensive source area of regional air pollution, and in Russia and central Asia, necessary sites for the analysis of hemispherical air pollution. Observation of OH/HO2 radicals which are the ultra-trace species playing a central role in tropospheric photochemistry will also be conducted.

Qualification for application
In order to promote the above studies, we call for scientists who have fundamental knowledge on atmospheric chemistry and have experience or interests in global or regional scale modeling, observational data analysis of greenhouse gases, or atmospheric chemistry observation. We particularly call for scientists who will engage to the following type of research in this fiscal year.

1) Source-sink modeling research of greenhouse gases

2) Atmospheric chemistry observation research of aerosols and air pollutant gases
To obtain and analyze basic data for the evaluation of climate and environmental impact of air pollution in Asia through conducting the continuous measurements and participating intensive campaigns for aerosol, ozone and HOx radicals in Japan, China, Russia and central Asia.

3) Chemical-transport modeling research based on emission inventory in Asia
To prepare future emission inventory data of atmospheric trace species in Asia and to participate development chemical weather forecast system or process study of future air quality change in Asia.

(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 theecosystems.Toachieve these objections, further process is required in modeling of ecosystem structure andfunction, and in the integration of such models to 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 preparation and the integration of the basic data base and knowledge in the relevant fields.

Qualification for application
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.

(5) Global Warming Research Program
   This research program explores the physical, chemical and biological mechanism responsible for global warming and attempt to make quantitative projection of future climate change.It covers three research subjects, i. e., global warming, carbon cycle, 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 Modeling 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.

Qualification for application
   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, chemistry, and biology and the ability to apply them 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 Earth Simulator and study climate phenomena by using these models.

1) The development phase of atmospheric and ocean models have been almost completed.The atmospheric model using icosahedral (quasi-uniform) grid system with horizontal mesh size of 5 km or less can simulate tropical cloud clusters and other mesoscale atmospheric systems explicitly without parameterizations.The ocean model using cubic-grid system with horizontal mesh size of 10 km or less can simulate the mesoscale eddies explicitly without parameterizations.Currently, climate phenomena are analyzed by using these models and improvement of the models are also carrying out.

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.

3) 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 which is far from complete.

Qualification for application
Candidates should hold a Ph.D. (or equivalent) in such fields as meteorology, physical oceanography, geophysical fluid dynamics, climate dynamics or related fields in physics.They should have experiences for atmosphere/ocean modeling and will be in charge the following items.
