CAWSES Space Weather International Collaborative Research Database in Japan

Climate And Weather of the Sun-Earth System (CAWSES)

Outline of CAWSES Space Weather International Collaborative Research Database in Japan (Significance and Purpose of Construction).

The ICSU-SCOSTEP (International Council for Science-Scientific Committee on Solar-Terrestrial Physics) which carried out the STEP program (1990-1997) and the S-RAMP program (1998-2002), has determined to promote the CAWSES (Climate And Weather of the Sun-Earth System) program for 2004-2008 as an international collaborative research program of the beginning of 21st century to understand the short term (Space Weather) and long term (Space Climate) variability of the integrated solar-terrestrial environment, and for its societal applications.

The following items are carried out in CAWSES.

  1. Observations research of short term variability (Space Weather) and long term variability (Space Climate) of solar-terrestrial environment
  2. Integrated study among the observation, theory, and modeling/simulation
For the short term variability (Space Weather) of the CAWSES, "CAWSES Space Weather International Collaborative Research Database in Japan" is constructed as an infrastructure of national cooperative research as our country positively participates.

Concretely, database construction of the fiscal 2003 and S-RAMP periods develops. Then analysis software and the database which added the analytical results in the ground and satellite observations acquired in fiscal 2004-2008 as CAWSES Space Weather International Collaborative Research and the common database which added calculation result to the software of the modeling/simulation is made. That our country independently makes it and that it makes common use database of the Japan leaving as a common basis which the researcher of the world can utilize for the space weather research has the important significance as an international contribution.

Plans for CAWSES Program

In the STEP program (1990-1997) and the S-RAMP program (1998-2002), large data of sun image, solar radio emission, interplanetary space, magnetosphere, ionosphere and the atmosphere observations were acquired. The data of about 21TB was accumulated in the whole in today. In S-RAMP Database (1998-2002), analysis software, and the modeling/simulation data were added to observational data, and the following items were carried out. As continuation and development of these Japan solar-terrestrial physics database creation, the database used as the base of CAWSES Space Weather International Collaborative Research (2004-2008) is created.

First, the data from which comprehension of a data donor was obtained by data with high use demand and use frequency is exhibited as an online database. Extensive data with many users and fundamental analysis software are dedicated to CD-ROM together, and they are distributed to main CAWSES international collaborative researchers in and outside the country (domestic distribution 200 and foreign distribution 250). About a lot of data with which the user was restricted, and especially the data changed into digital one from analogs, such as plot paper and a photograph, the CD-RAM/DVD-RAM original version is made and the electronization of data is measured. A lot of data which are solar picture, geomagnetism 1 second and an atmosphere optical observations, etc. are kept as source data to DVD-RAM.

In the 2004 fiscal year, while employing the making achievement and experience efficiently with S-RAMP database and the space weather database in the 2003 fiscal year, the CAWSES Space Weather International Collaborative Research Database which aims at the effective combination between an observations of short term variability (Space Weather) of the solar terrestrial system of the CAWSES done in a plan from 2004 for five years, and the modeling/simulation is started. Specifically the space weather research data is chosen from CAWSES data, and newer cosmic-ray and the optical observational data of the upper atmosphere are added, and a database is made.

There are the following as item.

  1. Solar and Cosmic rays data (Solar pictures and Electric wave images): One image = 1000¡ß1000 pixel¡ß£±byte = 1MB
  2. Magnetosphere data (magnetic field, plasma, particles): One-day data¡á86400¡ß3¡ß2bytes¡á516KB
  3. Ionosphere data (observations each point, geomagnetism 3 ingredient, an Aurora image) : One-day data¡á864000¡ß4¡ß4byes¡ß80points¡á830MB
  4. Atmosphere optical observational data : One-day data¡á500¡ß500 pixel¡ß1000¡ß4¡ß1byte¡á1,000MB
  5. Modeling / simulation data (Magnetic field model, Electron current, Kinetic simulation. etc.) : Sampling data¡á400¡ß100¡ß100¡ß8¡ß4bytes¡á128MB

These databases can be used for promotion of the space weather research of Japan and international contributions.

Public Disclosure of CAWSES Space Weather International Collaborative Research Database in Japan

Public disclosure of the CAWSES Space Weather International Collaborative Research Database as well as the case of S-RAMP database is classified into four kinds of categories shown below according to a user's number and amount of data, and exhibits a database.

Category1:The data with many users at until middle-scale is offered and exhibited on-line.
Category2:About a lot of data with many users, it is CD-ROM (DVD-ROM) original edition creation/press distribution.
Category3:About a lot of data with which the user was restricted, it is CD-RAM (DVD-RAM) original edition creation (number-of-volumes limitation), and it is a press and offer if required.
Category4:A lot of data kept as source data is kept with DVD-RAM, and is lent out if required.

It appropriates for the use as mentioned above.

The S-RAMP database catalog (in English and Japanese) is exhibited on the Internet from June, 1999 (http://center.stelab.nagoya-u.ac.jp/web1/sramp/index.html). The facilities of an international collaborative researcher are considered and the CAWSES Space Weather Research Database is exhibited by Web (http://center.stelab.nagoya-u.ac.jp/cawses/index.html) with the Space Weather Database in the 2003 fiscal year. The CAWSES Space Weather Research Database offer and public disclosure on line will be started in 2004 fiscal year and moreover, the contents are enriched. CD-ROM (DVD-ROM) creation/press distribution of the CAWSES Space Weather Research Database is carried to both data of observations and simulation/modeling like S-RAMP.

About concrete method and use restrictions of data public presentation, it depens on a data donor's conditions. However, the open data in Web will not be restricted in particular, if used academically. CD-ROM is distributed to the Collaborative-Research person who represents a research consortium in principle, and is further distributed according to a demand.

About use of a CAWSES Space Weather International Collaborative Research Database in Japan.

The collaborative researcher in and outside the country which participates in the CAWSES (Climate And Weather of the Sun-Earth System, 2004-2008) which solves a short-term variability (the space weather) and long term variability (space climate) of a solar terrestrial system is a subject of use. The remarkable researcher has overlapped also with the S-RAMP International Collaborative Researcher. In Japan, various observational data from solar to a terrestrial, analysis data, and a modeling/simulation result are gathered as space weather research, and the study group meeting of the space weather prediction is held several times every year. The participant in those meetings and study groups turns into a main use candidate. Moreover, since the space weather research is common to human beings, U.S., Europe, and China are also advanced systematically. The space weather researchers in the world are candidate users.

About the contents of use, it is indispensable to put in a database the data which the researcher of Japan observed at home. On the data analysis, the software of modeling/simulation and the calculation result which are developed and expanded by the Japanese researcher there is no method, except that we makes the database ourselves. By sending the space weather database of such Japanese original from our country, when a researcher in and outside the country carries out mutual use of many data by both international data and research information exchange, space weather international collaborative research common to human beings can be carried out more rationally. Thus, the use from a CAWSES international collaborative researcher in and outside the country is main. In addition, the space weather is interested in wider and larger communities in the world, and many open data in Web is referred to also from public general.
