Minutes of the mid-term review, MTR
SAAPS-MTR-99/00
Held at
ESTEC
28 February 2000
Lars Eliasson opened the meeting and the agenda was agreed.
Lars Eliasson presented the general status of the project. Work has continued according to the agreed time schedule.
Peter Wintoft presented the main activities since the last progress meeting.
Data collection and implementation has continued. LANL data on CD-rom have been received for the three years 1996-98. GOES electron data have been downloaded for the years 1995-99. The OMNI data set from 1980-99 is now also available. A bug in the OMNI data set was found when comparing OMNI data with ACE data. The OMNI data set provider has corrected the error. Anomaly data (more than 5000 anomalies) from TDRS-1 for the years 1983-1993 have been included with help from Wilkinson at NSSDC. Wilkinson expressed interested in the progress of our work.
Contacts with operators have continued and some more input data have been given that are useful for testing the prediction module. The response has been fairly weak from the operator side but potential interest in the project has been expressed.
Updates of the three technical notes were presented. Some analysis has been made, e.g., comparing the different anomaly data sets. This shows that there is a good correlation between some spacecraft but not between others. This must, however be further investigated before firm conclusions can be made. The approach to use different electron energies has been tested with the addition of 20 keV data.
Preliminary analysis of predictions with the model on web using a balanced input data set together with daily sum of Kp-values has been performed. Other parameters shall be included. Higher time resolution will improve the results in the further studies.
The Java code has been updated. Network and utility packages have been included.
Eight Action Items (listed below with comments as 4.1-4.8) were defined during the PM2 held in Kiruna 12-14 October:
4.1. Scheme for coding sensitive information shall be sent to Alain Hilgers for approval in the end of November 1999.
Each user will be given a user name and password. The user will not have direct access to the anomaly data or other data. It was decided to use a code with three digits and only for internal use within the project and the system. The database tools must be able to handle groups of anomaly data.
4.2. Alain Hilgers shall investigate the availability of other anomaly data sets at ESTEC. Information shall be sent to by end of October.
No systematic reports exit but larger anomalies are being recorded from ESOC. In case we would like to use them the operators need to be contacted directly. Alain Hilgers has one more data set that can be used for the project.
4.3. Peter Wintoft will send email remainder to those that have not responded and send the questionnaire to ESOC before the end of October.
Letter and questions were sent by email on 16 November 1999 and will be complemented by letters to ESOC first week of March.
4.4. Alain Hilgers will give names to contact at ESOC before end of October.
Names have been given by Alain Hilgers.
4.5. Peter Wintoft shall send information and questionnaire to SWEN before end of October
A description of SAAPS was emailed to SWEN on 27 October 1999.
4.6. Peter Wintoft shall investigate usefulness of environment data from polar orbits (at least DMSP and TIROS) before the end of November.
Availability of DMSP data has been investigated. It is found to be too expensive to include DMSP data. Decision was to investigate other sources of LEO particle data.
4.7. Peter Wintoft shall submit the URD for WP110 to Alain Hilgers before 31 October in pdf-format. Alain Hilgers shall notify in a couple of days if critical problems exist in the URD.
The URD was delivered on 28 October 1999. Response from Alain Hilgers was received on 5 November.
4.8. A draft version of the URD for WP310 shall be sent to Alain Hilgers by mid-November.
Draft version was delivered on 17 November 1999.
Six of action items are closed. The remaining ones are letters to ESOC (will be sent during March) and the investigation of LEO data.
The URD was discussed. The section on coding scheme, organization of anomaly data and user access (page 10 in the URD) will be modified in accordance with the agreement made in point 4.1 above.
The availability of other solar magnetograms especially European ones will be investigated.
A table of the meta-data will be included.
Apart from the above the URD was found to be acceptable. An updated version will be sent to Alain Hilgers week 10.
The approach made in the technical note is satisfactory.
Peter Wintoft gave a short report on the status of data in the database and the developed tools.
The work on WP130 will start in March.
Peter Wintoft presented the status of the work on the satellite anomaly analysis module. Work so far is satisfying.
Some more modules will be implemented before it can be put on web for public testing.
The module for the user to enter the list of events for analysis and to plot the data, e.g., as time series plot and to perform superposed epoch analysis shall be implemented.
Description and help information shall be implemented.
The work on WP230 will start in March.
Peter Wintoft presented the status of the satellite anomaly prediction module. More models shall be added, at least one to predict single event upsets, e.g., based on high-energy solar protons.
More information on what is plotted and help information shall be added and the plots will be made so it is easier to determine times with increased risk for anomalies.
Environment data shall be included in the prediction plots.
The work on WP330 will start in April.
Some available analysis and prediction modules as well as software were demonstrated.
No changes were proposed regarding the schedule and deliverables.
It was decided to deliver the SRD at the end of March. After verified delivery the contractor can send the invoice for progress payment.
Peter Wintoft will send questionnaires to ESOC during March.
Peter Wintoft will continue the investigation of the availability of LEO data. Report will be given at the next progress meeting.
Peter Wintoft will investigate the availability of other solar magnetograms especially European ones. Information will be included in the updated version of the URD for WP110.
Peter Wintoft will send an updated version of the URD for WP110 to Alain Hilgers during week 10.
Alain Hilgers will, during week 9, provide a new anomaly data set for which confidentiality will be kept.
No other matters were discussed.
The date of the next progress meeting was discussed. June in Lund was proposed.
