2003Announcement of Research Positions
for The Frontier Research System for Global Change (FRSGC)
Please mind that following information is run as a reference. Applications for those positions have been closed.
Global changes, such as global warming and climatic anomalies, are serious problems which affect the ecosystem of nature and the future of human beings. The prediction and better understanding of these problems are pressing issues. FRSGC attempts to understand the complicated interactions among the atmosphere, ocean and land surface. Regarding the earth as one system, we develop an integrated model 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. The research period is 20 years starting from 1997, (divided into two 10-year periods), and the results of the research will be evaluated by outside experts every 5 years.
FRSGC is a project conducted at the Japan Marine Science and Technology Center (JAMSTEC).
The objective of this project is to elucidate the various processes contributing to global change through data analysis and model experiments. It is one of the three sister projects which includes observations of earth by satellite and ship (FORSGC), and the development of the “Earth Simulator”, which was completed in March 2002. FRSGC also works a channel to send research scientists to IPRC (International Pacific Research Center) and the IARC (International Arctic Research Center) which was established for the cooperation in global change research between Japan and the US under the Common Agenda. The research scientist of FRSGC work during the contract period under supervision of our distinguished leaders.
In the coming fiscal year, we invite applicants for six research programs (Climate Variations, Hydrological Cycle, Global Warming, Atmospheric Composition, Ecosystem Change and Integrated Modeling).
In addition, under the Ministry of Education, Culture, Sports, Science and Technology (MEXT)’s launched a new research initiative named “Project for Sustainable Coexistence of Human, Nature and the Earth” FRSGC has three subprojects ;
The period of the project is FY 2002?FY 2006 (from April 2002 to March 2007).
We also invite applicants for these subprojects of the “Project for Sustainable Coexistence of Human, Nature and the Earth”.
(1) Climate Variations Research Program
1) For Ocean and/or Atmosphere Climate Modeling and Predictability
2) For developing J-COPE (Japan Coastal Ocean Predictability Experiment)
In addition to existing meteorological, hydrological and land-use data, we will fully utilize intensively observed data obtained through international projects such as GEWEX Asian Monsoon Experiment program (GAME), as well as the data (to be) observed by the Frontier Observation Research System for Global Change (FORSGC), remote sensing data (TRMM, SSM/I, GMS etc.) and others.
As for the modeling, we basically utilize GCMs and some regional models, such as RAMS, MM5 and ARPS. In addition, with the intention of developing models covering the points below, we are trying to elucidate mechanisms of changes in precipitation and the hydrological cycle (diurnal, seasonal, annual and interannual) in Asia. We are also trying to develop prediction methods for those mechanisms.
Research Scientist who have expertise and sufficient background on the following fields are highly appreciated:
(3) Global Warming Research Program
1) Global Warming Research
2) Carbon Cycle Research
3) Paleoclimate Research
(4) Atmospheric Composition Research Program
2) Atmospheric composition data analysis research
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.
1) Ecosystem - Atmosphere interaction modeling group
2) Ecosystem architecture modeling group
3) Ecosystem geographical distribution modeling group
4) Marine biological process modeling group
1. Spectral atmosphere model with a horizontal resolution T213 and
50 layers in the vertical, world ocean model with 0.1 horizontal resolution
and 50 layers in the vertical, and a coupled A-O GCM consisting of the
two. An objective is to carry out long-term global warming experiments
with eddy containing oceans.
Modeling experts now being sought are expected to be engaged in
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:
We invite applications from specialists for the above work.
«Development of Integrated Earth System Models»
«Research development of a new four-dimensional variational (4D-VAR) data assimilation system using an adaptive filter approach and assessment of the products»
In order to better describe the dynamic state of a climate system and contribute to improving predictability skills for seasonal variations, Data Assimilation Research Project aims at developing an adaptive filter and thereby constructing a new advanced 4D-VAR data assimilation system for climate variations. An adaptive filter method exploited here is a combination of the adjoint and the ensemble Kalman filter method with an aim at utilizing the advantages of both assimilation methods. The adaptive filter is planned to be incorporated into a dynamically coupled climate model that will be constructed and tuned up by a research group at the Earth Simulator Center (ESC). Firstly, data assimilation systems for each component model will be constructed using the adaptive filter approach, respectively, which are used to seek the optimal ensemble number and parameter values for seasonal variations. Secondly, these models will be integrated to make the comprehensive reanalysis dataset with dynamical consistency in the coupled system from a variety of observational data. Lastly, after a close examination of the effectiveness of the product in enhancing predictability and state estimation of seasonal variations, the new advanced data assimilation system is assessed and improved towards a better assimilation system.
A computer system with a multi-purpose server as well as a high performance server capable of vector calculations has been set up at FRSGC. In addition, a network system with access to super computers at Japan Marine Science and Technology Center has been constructed. All FRSGC research scientists are eligible for applying for using Earth Simulator.
