The following proposal has been submitted to COSPAR Bureau in March 23rd, 2005:
It is now clear to everybody that the current standard AE8/AP8 model for ionising
particle specification in the radiation belts must be updated. But such an objective
is quite difficult to reach, just as a reminder, to develop AE8/AP8 model in the seventies
was 10 persons full time for ten years. On the other hand a meeting was held at NASA/GSFC
last October and one conclusion was that world-wide efforts must be combined because
not any individual group has the human resource to perform these new models by themselves.
At the NASA meeting, both NASA and ESA agreed to proceed under the COSPAR/PRBEM (Panel
on Radiation Belt Environment Model previously PSRB) umbrella. The idea is to create
an international group of expert well distributed around the world to set up a common
framework for everybody involved in this field. The idea is to have a maximum of two
experts per country (assuming Europe is one country) known to be active in radiation
Planned activities of the international group of experts:
- Set up guidelines to process in-situ data on a common basis.
- Decide in which form the new models will have to be.
- Centralise all progress done world-wide to advise the community.
- Try to organise world-wide activities as a project to ensure complementarities and
more efficiencies between all efforts done.
- A web site will be set up at ONERA to gather all information.
COSPAR Bureau decision on March 24, 2005:
The Bureau accepted the proposal to have PRBEM serve
as an umbrella for the creation of an international group of experts as described
above (in the form it has been submitted during the Program Committee meeting of March
2005). The Bureau views the request to conduct this activity under the COSPAR/PRBEM
umbrella as positive for an activity which should be conducted internationally.
Working group composition and planned activities:
It is planned to put the progress on new radiation belt models in two phases:
A first working has been set up for phase one. It is composed of experts in radiation
belt studies located in different countries where space research is active. The working
group for phase two will be set up later and in this phase it is expected to involve
user's such as space industries and space agencies. This two phases program will allow
to separate model development and model evaluation (it is always better and fair to
have a group to evaluate models independently of those who produce the model itself).
- Define user needs, produce guidelines to process and analyse in-situ data, produce
guidelines to develop new models.
- New models evaluation and dissemination
Current working group for phase one:
The following area of expertise are covered:
Radiation effects (4)
Data base (4)
Data acquisition (5)
Instrument response (3)
Data analysis (5)
Radiation belt models (empirical & theoretical) (4)
Links with other body:
ISO WG4 (1)
Working group progress:
Right now two documents are available:
and one document is in progress:
- User's needs
- Standard file format guidelines
- Data analysis procedure
If one has any inputs, please do not hesitate to provide them to your representative
listed above. The working group will compile all those inputs and integrate them in
the documents if they are judged relevent.
- Standard file format guidelines for raw data (counts)
